PSPDFConfiguration

Objective-C


@interface PSPDFConfiguration
    : PSPDFBaseConfiguration <PSPDFConfigurationBuilder *> <PSPDFOverridable>

Swift

class PDFConfiguration : BaseConfiguration<PDFConfigurationBuilder>, Overridable

A PDFConfiguration defines the behavior of a PDFViewController. It uses the builder pattern via PDFConfigurationBuilder to create an immutable copy via a block.

  • Set a page mode defined in the enum. Defaults to .automatic. Reloads the view, unless it is set while rotation is active. Thus, one can customize the size change behavior by setting this within a size transition animation block. Ignored when pageTransition is set to .scrollContinuous.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFPageMode pageMode;

    Swift

    var pageMode: PageMode { get }

  • Defines the page transition. Defaults to .scrollPerSpread.

    Warning

    If you change the property dynamically in viewWillTransitionToSize:withTransitionCoordinator:, wait for the transition to finish using the coordinator’s completion block, otherwise the controller will get in an invalid state. Child view controllers get rotation events AFTER the parent view controller, so if you’re changing this from a parent viewController, for PSPDFKit the rotation hasn’t been completed yet, and your app will eventually crash. In that case, dispatch the work async on the main queue. You might just want to set updateSettingsForBoundsChangeBlock and set your properties there.

    Note

    We enable the automaticallyAdjustsScrollViewInsets by default. If you don’t want this behavior, subclass reloadData and set this property to false.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFPageTransition pageTransition;

    Swift

    var pageTransition: PageTransition { get }

  • Shows first document page alone as “cover mode”. Defaults to true.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isFirstPageAlwaysSingle) BOOL firstPageAlwaysSingle;

    Swift

    var isFirstPageAlwaysSingle: Bool { get }

  • Controls whether spreads can grow larger than the actual view. Defaults to .adaptive. This can be helpful on smaller screens to make the content more readable.

    Note

    This property has no effect if the page transition is anything but PageTransition.scrollPerSpread or PageTransition.scrollContinuous.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFConfigurationSpreadFitting spreadFitting;

    Swift

    var spreadFitting: PDFConfiguration.SpreadFitting { get }

  • Only useful for PageTransition.curl. Clips the page to its boundaries, not showing a pageCurl on empty background. Defaults to true. Set to false if your document is variably sized.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL clipToPageBoundaries;

    Swift

    var clipToPageBoundaries: Bool { get }

  • Additional insets to apply to the document scroll view’s frame.

    See

    -[PSPDFDocumentViewLayout additionalScrollViewFrameInsets]

    Declaration

    Objective-C

    @property (nonatomic, readonly) UIEdgeInsets additionalScrollViewFrameInsets;

    Swift

    var additionalScrollViewFrameInsets: UIEdgeInsets { get }

  • Additional insets to apply to the layout’s content.

    Note

    This only has an effect if the page transition is either .scrollPerSpread or .scrollContinuous.

    See

    Declaration

    Objective-C

    @property (nonatomic, readonly) UIEdgeInsets additionalContentInsets;

    Swift

    var additionalContentInsets: UIEdgeInsets { get }

    Swift

    var isShadowEnabled: Bool { get }

  • Set default shadowOpacity. Defaults to 0.7.

    Declaration

    Objective-C

    @property (nonatomic, readonly) CGFloat shadowOpacity;

    Swift

    var shadowOpacity: CGFloat { get }

  • Background color behind the page view. Defaults to a dynamic color which matches the current UIUserInterfaceStyle.

    Declaration

    Objective-C

    @property (nonatomic, readonly) UIColor *_Nonnull backgroundColor;

    Swift

    var backgroundColor: UIColor { get }

  • Allowed appearance modes for BrightnessViewController. Defaults to .all. .default is always assumed to be available. Set to only .default to disable appearance mode picker UI. This needs to be set before BrightnessViewController is presented.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFAppearanceMode allowedAppearanceModes;

    Swift

    var allowedAppearanceModes: PDFAppearanceMode { get }

  • Page scrolling direction. Defaults to .horizontal. Only relevant for scrolling page transitions.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFScrollDirection scrollDirection;

    Swift

    var scrollDirection: ScrollDirection { get }

  • Deprecated

    Deprecated in PSPDFKit 11.5 for iOS. Using this property has no effect.

    Sets the scroll view inset adjustment mode. Defaults to ScrollInsetAdjustment.fixedElements. This is only evaluated for PageTransition.scrollContinuous & ScrollDirection.vertical.

    Note

    This is similar to automaticallyAdjustsScrollViewInsets but more tailored to PSPDFKit’s use case.

    Warning

    UIViewController’s automaticallyAdjustsScrollViewInsets will always be disabled. Don’t enable this property.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFScrollInsetAdjustment scrollViewInsetAdjustment;

    Swift

    var scrollViewInsetAdjustment: ScrollInsetAdjustment { get }

  • Minimum zoom scale. Defaults to 1.

    Declaration

    Objective-C

    @property (nonatomic, readonly) float minimumZoomScale;

    Swift

    var minimumZoomScale: Float { get }

  • Maximum zoom scale for the scrollview. Defaults to 20.

    Declaration

    Objective-C

    @property (nonatomic, readonly) float maximumZoomScale;

    Swift

    var maximumZoomScale: Float { get }

  • Determines whether the scrolling is locked in a certain direction when interacting with the document’s pages.

    The default value of this property is .adaptive, which means the directional lock on the underlying scroll view will be enabled or disabled depending on the context in which the document is being presented. Setting explicit true or false values will directly affect how the scroll view behaves, regardless of presentation context.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFAdaptiveConditional documentViewLayoutDirectionalLock;

    Swift

    var documentViewLayoutDirectionalLock: AdaptiveConditional { get }

  • If true, shows an UIActivityIndicatorView on the top right while page is rendering. Defaults to true.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isRenderAnimationEnabled) BOOL renderAnimationEnabled;

    Swift

    var isRenderAnimationEnabled: Bool { get }

  • Position of render status view. Defaults to .top.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFRenderStatusViewPosition renderStatusViewPosition;

    Swift

    var renderStatusViewPosition: RenderStatusViewPosition { get }

  • The action that happens when the user double taps somewhere in the document. Defaults to .smartZoom.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFTapAction doubleTapAction;

    Swift

    var doubleTapAction: TapAction { get }

  • If set to true, automatically focuses on selected form elements. Defaults to false.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isFormElementZoomEnabled) BOOL formElementZoomEnabled;

    Swift

    var isFormElementZoomEnabled: Bool { get }

  • Whether tapping on leading/trailing edges of the document view should trigger changing to the previous/next page. Defaults to true.

    Taps detected near the edge cancel the double-tap to zoom gesture so the default margin is quite narrow. This gesture allows fast tapping to quickly browse through a document.

    See

    animateScrollOnEdgeTaps and scrollOnEdgeTapMargin for related properties.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isScrollOnEdgeTapEnabled) BOOL scrollOnEdgeTapEnabled;

    Swift

    var isScrollOnEdgeTapEnabled: Bool { get }

  • Whether to animate scrolling to the previous or next page when tapping the edges of the view. Defaults to false to enable very fast browsing through a document.

    This is only effective if scrollOnEdgeTapEnabled is set to true.

    Note

    This property has no effect if you are using PageTransition.curl.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=animateScrollOnEdgeTaps) BOOL animateScrollOnEdgeTaps;

    Swift

    var animateScrollOnEdgeTaps: Bool { get }

  • The margin in points from the view’s sides in which tapping should trigger scrolling to the previous/next page. Defaults to 44.

    This is only effective if scrollOnEdgeTapEnabled is set to true.

    Note

    This property has no effect if you are using PageTransition.curl.

    Declaration

    Objective-C

    @property (nonatomic, readonly) CGFloat scrollOnEdgeTapMargin;

    Swift

    var scrollOnEdgeTapMargin: CGFloat { get }

  • Set the default link action for pressing on LinkAnnotations. Default is .openSafari.

    Note

    If modal is set in the link, this property has no effect.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFLinkAction linkAction;

    Swift

    var linkAction: LinkAction { get }

  • Deprecated

    Deprecated in PSPDFKit 12.3 for iOS. Use ‘contentMenuConfiguration’, ‘PDFViewControllerDelegate.pdfViewController(:menuForText:onPageView:appearance:suggestedMenu:)’ or ‘PDFViewControllerDelegate.pdfViewController(:menuForImage:onPageView:appearance:suggestedMenu:)’ instead.

    May be used to customize other displayed menu actions when text is selected. Defaults to [.search, .define, .speak, .share, .copy, .annotationCreation].

    An option set that controls which actions are displayed in the legacy menu for selected text and images. Default: [.search, .define, .speak, .share, .copy, .annotationCreation].

    Warning

    This configuration option is deprecated. To configure which annotation tools are avalable in the menu for selected text, use the contentMenuConfiguration configuration option instead. To customize menu for selected text directly, use the PSPDFViewControllerDelegate/pdfViewController:menuForText:onPageView:appearance:suggestedMenu: delegate method. To customize the menu for selected images, use the PSPDFViewControllerDelegate/pdfViewController:menuForImage:onPageView:appearance:suggestedMenu: delegate method.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFTextSelectionMenuAction allowedMenuActions;

    Swift

    var allowedMenuActions: TextSelectionMenuAction { get }

  • A boolean value that controls whether selecting text that is part of page content is possible in the view controller. Default: true.

    Note

    This implies that the document contains acutual text glyphs, which isn’t always the case. Sometimes text is represented by “baked in” vectors or bitmaps, in which case PSPDFKit can’t detect it and users won’t be able to select it.

    Important: Setting this property to false will also disable selecting images, and setting the imageSelectionEnabled configuration option to true will have no effect.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isTextSelectionEnabled) BOOL textSelectionEnabled;

    Swift

    var isTextSelectionEnabled: Bool { get }

  • A boolean value that controls whether selecting images that are part of page content is possible in the view controller. Default: true.

    Note

    This implies that the image is an actual bitmap, which isn’t always the case. Often images in PDF documents are vectors, in which case PSPDFKit can’t detect them and users won’t be able to select them.

    Important: Setting this property to true has no effect if selecting text has been disabled using the textSelectionEnabled configuration option.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isImageSelectionEnabled) BOOL imageSelectionEnabled;

    Swift

    var isImageSelectionEnabled: Bool { get }

  • Defines how the text is selected. Defaults to .automatic.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFTextSelectionMode textSelectionMode;

    Swift

    var textSelectionMode: TextSelectionMode { get }

  • Specifies whether the selection view snaps to word boundaries when selecting text.

    Setting this to true will:

    • adjust the text selection to word boundaries when resize handles are released,
    • ensure selection starts on a word boundary in .simple on Mac Catalyst.

    A new selection always first selects a full word in .regular. That’s also the case on iOS, regardless of the set selection mode.

    Defaults false.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL textSelectionShouldSnapToWord;

    Swift

    var textSelectionShouldSnapToWord: Bool { get }

  • Modify what annotations are editable and can be created. Set to nil to completely disable annotation editing/creation. Defaults to all available annotation strings.

    In the case of .widget, whether that type is included in editableAnnotationTypes determines whether users can interact with PDF forms to edit form field values rather than editing the form elements themselves. In other words, editing the properties like background color or the position of form elements on the page is not supported.

    Warning

    Some annotation types are only behaviorally different in PSPDFKit but are mapped to basic annotation types, so adding those will only change the creation of those types, not editing. Example: If you add .ink but not .signature, signatures added in previous session will still be editable (since they are ink annotations). On the other hand, if you set .signature but not .ink, then your newly created signatures will not be movable.

    See

    PSPDFAnnotation.h for additional comments.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSSet<PSPDFAnnotationString> *_Nonnull editableAnnotationTypes;

    Swift

    var editableAnnotationTypes: Set<Annotation.Tool> { get }

  • Shows a custom cell with configurable color presets for the provided annotation types. Defaults to PSPDFAnnotationTypeAll. Set to PSPDFAnnotationTypeNone to completely disable color presets.

    Note

    The presets are only displayed if the PSPDFStyleManager returns supported annotation types only.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFAnnotationType typesShowingColorPresets;

    Swift

    var typesShowingColorPresets: Annotation.Kind { get }

  • Customize the inspector items globally.

    This currently affects AnnotationStyleViewController and FreeTextAccessoryView.

    The dictionary is keyed by annotation type (PSPDFAnnotationString). The values are either:

    See AnnotationStyle.Key for a list of supported keys.

    The block option is especially useful to customize the available inspector properties based on some annotation attributes. (e.g., show callout options based on the free text annotation intentType).

    Note

    If you want to disable all color editing, be sure to also remove the relevant type from typesShowingColorPresets (also available in PDFConfiguration).

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSDictionary<PSPDFAnnotationString, id> *_Nonnull propertiesForAnnotations;

    Swift

    var propertiesForAnnotations: [Annotation.Tool : Any] { get }

  • Shows a toolbar with text editing options (FreeTextAccessoryView) above the keyboard, while editing free text annotations. Defaults to true. You need to set this property before the text annotation is edited.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isFreeTextAccessoryViewEnabled) BOOL freeTextAccessoryViewEnabled;

    Swift

    var isFreeTextAccessoryViewEnabled: Bool { get }

  • Controls how bookmarks are displayed and managed. While bookmarks have a custom order, the default is set to BookmarkManager.sortOrderPageBased.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFBookmarkManagerSortOrder bookmarkSortOrder;

    Swift

    var bookmarkSortOrder: BookmarkManager.SortOrder { get }

  • Sets the page’s bookmark indicator mode. Defaults to .off. Depending on this mode, a button indicating the current bookmark status of the page will be displayed on the page itself. Tapping the button will toggle the bookmark mode. For customizing the bookmark indicator, see PSPDFBookMarkIndicatorButton.h

    See

    bookmarkIndicatorInteractionEnabled

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFPageBookmarkIndicatorMode bookmarkIndicatorMode;

    Swift

    var bookmarkIndicatorMode: PageBookmarkIndicatorMode { get }

  • Enables/disables the bookmark indicator’s interaction. Defaults to true. If this is enabled, tapping the indicator will bookmark on un-bookmark the page it is displayed on. Use this in conjunction with bookmarkIndicatorMode to get the desired behavior

    See

    bookmarkIndicatorMode

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL bookmarkIndicatorInteractionEnabled;

    Swift

    var bookmarkIndicatorInteractionEnabled: Bool { get }

  • Defines whether it is possible to add multiple bookmarks on the same page via the UI. If this is enabled:

    • the bookmark list’s add button is always enabled.
    • the bookmark button item removes all bookmarks on a page, if there are any, if tapped.

    This property does not affect adding bookmarks via the bookmark manager, where adding multiple ones for a single page is always supported.

    Defaults to false.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL allowMultipleBookmarksPerPage;

    Swift

    var allowMultipleBookmarksPerPage: Bool { get }

  • Controls the behavior of the user interface view, defaults to .automaticNoFirstLastPage.

    PDFViewController can display additional information and interactive elements for the visible document as an overlay called the user interface view. While the elements in the user interface view are controlled by various other configuration properties, userInterfaceViewMode controls the initial visibility of the user interface view and whether the visibility is updated on user interaction.

    For immersive reading, the visibility of the navigation bar of the parent navigation controller can be tied to the user interface view by setting shouldHideNavigationBarWithUserInterface to true, except in UserInterfaceViewMode.never. In this mode, the visibility of the navigation bar is left untouched to prevent getting “trapped” inside a PDFViewController due to the lack of the back- or close button typically present in the navigation bar.

    Note

    Explicit, manual calls to setUserInterfaceVisible(_:animated:) on a PDFViewController always take precedence over the value of this property.

    Warning

    The visibility of the user interface view is not updated when changing this mode once a PDFViewController is on screen! To programmatically show/hide the user interface view, use setUserInterfaceVisible(_:animated:) instead.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFUserInterfaceViewMode userInterfaceViewMode;

    Swift

    var userInterfaceViewMode: UserInterfaceViewMode { get }

  • Sets the way the user interface view will be animated. Defaults to .fade.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFUserInterfaceViewAnimation userInterfaceViewAnimation;

    Swift

    var userInterfaceViewAnimation: UserInterfaceViewAnimation { get }

  • Changes the user interface style for the contents when displayed inside a half-modal or a popover. Defaults to .card.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFPresentationHalfModalStyle halfModalStyle;

    Swift

    var halfModalStyle: PresentationHalfModalStyle { get }

  • Note

    Requires a setNeedsLayout on PSPDFUserInterfaceView to update if there’s no full reload.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isPageLabelEnabled) BOOL pageLabelEnabled;

    Swift

    var isPageLabelEnabled: Bool { get }

  • Enable/disable the top document label overlay. Defaults to .adaptive: The document label is shown if there’s not enough space to set the navigation bar title instead.

    Note

    Requires a setNeedsLayout on the PDFViewController view to update if there’s no full reload.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFAdaptiveConditional documentLabelEnabled;

    Swift

    var documentLabelEnabled: AdaptiveConditional { get }

  • Automatically hides the user interface when the user starts scrolling to different pages in the document. Defaults to true.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL shouldHideUserInterfaceOnPageChange;

    Swift

    var shouldHideUserInterfaceOnPageChange: Bool { get }

  • Should show the user interface view on viewWillAppear:, unless the user interface is disabled. Defaults to true.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL shouldShowUserInterfaceOnViewWillAppear;

    Swift

    var shouldShowUserInterfaceOnViewWillAppear: Bool { get }

  • If the home indicator height should be included when calculating the insets for the document view. Defaults to false.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL shouldAdjustDocumentInsetsByIncludingHomeIndicatorSafeAreaInsets;

    Swift

    var shouldAdjustDocumentInsetsByIncludingHomeIndicatorSafeAreaInsets: Bool { get }

  • Allow PSPDFKit to change the title of this view controller. If true, the controller title will be set to the document title or nil, depending on whether the document label is visible or not. Set to false, to manage the viewController title manually.

    Defaults to true.

    On Mac Catalyst, we suggest to not show a toolbar and set allowWindowTitleChange instead.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL allowToolbarTitleChange;

    Swift

    var allowToolbarTitleChange: Bool { get }

  • Mac Catalyst specific: Sets the documentURL and title of the current window. This uses NSDocumentController internally to set the toolbar and set the dirty state.

    This method has no effect on iOS. Defaults to false.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL allowWindowTitleChange;

    Swift

    var allowWindowTitleChange: Bool { get }

  • If true, the navigation bar will be hidden when the user interface is hidden. If false, the navigation will stay shown or hidden depending on the value of [UINavigationController navigationBarHidden]. Defaults to true.

    Swift

    var shouldHideStatusBar: Bool { get }

  • If true, the status bar will be hidden when the user interface is hidden. Defaults to true.

    Note

    This setting is ignored when the navigation bar is always visible (shouldHideNavigationBarWithUserInterface and UINavigationController.isNavigationBarHidden both set to false).

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL shouldHideStatusBarWithUserInterface;

    Swift

    var shouldHideStatusBarWithUserInterface: Bool { get }

  • Defines if the floating redaction info button, that is shown when there are uncommitted redactions in the document, should be shown in the user interface view.

    Defaults to true, if the Redaction component is included in the license.

    Note

    Setting this property will have no effect if the Redaction component is not included in the license.

    Note

    When disabling this and you support redaction annotations, applying redactions will need to be handled manually.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL shouldShowRedactionInfoButton;

    Swift

    var shouldShowRedactionInfoButton: Bool { get }

  • Whether the usage hint alert should be shown the first time the user selects the redaction tool. Defaults to true, if the Redaction component is included in the license.

    @property (nonatomic, readonly) PSPDFThumbnailBarMode thumbnailBarMode;

    Swift

    var thumbnailBarMode: ThumbnailBarMode { get }

  • Controls the placement of the scrubber bar. Defaults to .horizontal.

    Note

    Customizing scrubberBarType is supported only when thumbnailBarMode is .scrubberBar. Otherwise, setting this property to any value other than .horizontal won’t have any effect.

    Declaration

    Objective-C

    Swift

    var isCreateAnnotationMenuEnabled: Bool { get }

  • The array of annotation type groups shown in the annotation creation menu. Annotation types that are not listed in editableAnnotationTypes will be ignored.

    On iOS 16 and newer, annotation type groups will be separated from each other when the annotation creation menu is presented using secondary click interaction. Otherwise, there’s no visual separation between the groups.

    Setting this property to an empty array doesn’t prevent the annotation creation menu from being presented, as it may also contain other actions, such as Paste. To disable the annotation creation menu completely, set the createAnnotationMenuEnabled configuration property to false.

    Note

    Presenting the annotation creation menu requires the Annotation Editing component to be enabled for your license.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly) NSArray<PSPDFAnnotationGroup *> *_Nonnull createAnnotationMenuGroups;

    Swift

    var createAnnotationMenuGroups: [PSPDFAnnotationGroup] { get }

  • Enables natural drawing for ink annotations. Defaults to false.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL naturalDrawingAnnotationEnabled;

    Swift

    var naturalDrawingAnnotationEnabled: Bool { get }

  • The confidence threshold at which the Magic Ink tool should replace the drawn ink with a corresponding shape annotation. This should always be in the range [0, 100], with 100 representing a perfect match.

    Magic Ink uses the tool .ink with the variant .inkMagic.

    Defaults to 70.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSUInteger magicInkReplacementThreshold;

    Swift

    var magicInkReplacementThreshold: UInt { get }

  • Determines whether new annotations are created when strokes end. Defaults to .automatic.

    The PDF spec allows an unlimited number of separate paths per ink annotation object. They all need to have the same color and width.

    Note

    This does not affect undo - undo is smart and tracks paths individually.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFDrawCreateMode drawCreateMode;

    Swift

    var drawCreateMode: DrawCreateMode { get }

  • If true, asks the user to specify a custom annotation username (“author”) when first creating a new annotation

    This is triggered by the AnnotationStateManager changing its state.

    A default name will already be suggested based on the device name. You can change the default username by setting -[PSPDFDocument defaultAnnotationUsername]. Defaults to true.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL shouldAskForAnnotationUsername;

    Swift

    var shouldAskForAnnotationUsername: Bool { get }

  • Controls if a second tap to an annotation that allows inline editing enters edit mode. Defaults to true. (The most probable candidate for this is FreeTextAnnotation)

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL annotationEntersEditModeAfterSecondTapEnabled;

    Swift

    var annotationEntersEditModeAfterSecondTapEnabled: Bool { get }

  • Scrolls to affected page during an undo/redo operation. Defaults to true.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL shouldScrollToChangedPage;

    Swift

    var shouldScrollToChangedPage: Bool { get }

  • Controls the sound annotation player style. Defaults to .bottom.

    This must be set in the configuration when the PDFViewController is initialized. Applying a configuration that changes this property after loading is not supported.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFSoundAnnotationPlayerStyle soundAnnotationPlayerStyle;

    Swift

    var soundAnnotationPlayerStyle: SoundAnnotationPlayerStyle { get }

  • Whether PSPDFKit should save automatically in response to certain UI triggers, such as the app entering the background or the view disappearing.

    Defaults to true because users generally expect saving to be automatic on iOS. The exact save triggers may change between PSPDFKit versions. See https://pspdfkit.com/guides/ios/annotations/annotation-and-bookmark-saving-triggers/ for details.

    Set this property to false if you want to save with different triggers, such as when the user manually requests this. You can save using the Document method save(options:) or save(options:completion:).

    To fully disable a Document from saving, set its annotationSaveMode to .disabled. See https://pspdfkit.com/guides/ios/annotations/annotation-saving-mechanism/ for details.

    Implement PDFDocumentDelegate to be notified when automatic saving succeeds or fails.

    Declaration

    Objective-C

    @property (nonatomic, readonly, getter=isAutosaveEnabled) BOOL autosaveEnabled;

    Swift

    var isAutosaveEnabled: Bool { get }

  • Whether automatic saving should happen on a background thread.

    Defaults to false, which means automatic saving will run on the main thread.

    If saving on the main thread is a performance issue due to saving large documents then this property can be set true to tell PSPDFKit to auto-save on a background thread.

    Note

    Make sure that you don’t re-create the Document object if you enable background saving, otherwise you might run into race conditions where the old object is still saving and the new one might load outdated or corrupted data.

    This property has no effect if automatic saving is disabling by setting isAutosaveEnabled to false. See isAutosaveEnabled for details about automatic saving.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL allowBackgroundSaving;

    Swift

    var allowBackgroundSaving: Bool { get }

  • Describes the time limit for recording sound annotations in seconds. After this time has been reached, the recording will stop.

    Defaults to 300 (= 5 minutes).

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSTimeInterval soundAnnotationTimeLimit;

    Swift

    var soundAnnotationTimeLimit: TimeInterval { get }

  • Defines the default options when a sound annotation is created for recording.

    Defaults to an empty dictionary in which case following set is used:

    AVFormatIDKey: @(kAudioFormatLinearPCM) AVSampleRateKey: @(annotation.rate) // 22050 AVNumberOfChannelsKey: @(annotation.channels) // 1 AVLinearPCMBitDepthKey: @(annotation.bits) // 16

    Make sure to set a combination that are supported in

    • AVAudioRecorder
    • AVPlayer

  • Controls whether to display search results directly in a PDF, or as a list in a modal. Defaults to .modal.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFSearchMode searchMode;

    Swift

    var searchMode: SearchMode { get }

  • If a search result is selected, we scroll to the page to make it visible. Defaults to PSPDFAutomaticSearchResultZoomScale to indicate automatic scale based on the result we’re zooming into.

    If this is set to 1, no zooming is performed. Increase this to zoom to the search result. This value will be clamped by maximumZoomScale and should be set below. Values smaller than 1 and other than PSPDFAutomaticSearchResultZoomScale will be clamped to 1 as well.

    Note

    This value will be used as a guidance. In case the zoom would be too large, we reduce the scale to ensure the object fits the screen.

    Declaration

    Objective-C

    @property (nonatomic, readonly) CGFloat searchResultZoomScale;

    Swift

    var searchResultZoomScale: CGFloat { get }

  • Whether signatures should be saved after creation.

    This will be ignored (and signatures will not be saved) if signatureStore is nil.

    Defaults to .saveIfSelected, which means the user is given the choice whether to save signatures or not.

    To always save signatures without giving the user the choice, set a signatureStore and set signatureSavingStrategy to .alwaysSave.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFSignatureSavingStrategy signatureSavingStrategy;

    Swift

    var signatureSavingStrategy: SignatureSavingStrategy { get }

  • Defines if the user should be able to select certificates for digitally signing a document, when creating a new signature. Defaults to .ifAvailable.

    Will always show the certificate button on the signature creation UI, when set to .always. Will never show the certificate button on the signature creation UI, when set to .never. Will only show the certificate button on the signature creation UI, when there are registeredSigners on the shared PDFSignatureManager, when set to .ifAvailable. This is the default mode.

    This is only used if your license contains the Digital Signatures component and was originally purchased before the introduction of the Electronic Signatures component in March 2021. If you originally purchased after this date, Digital Signatures does not provide any UI for adding signatures. The Electronic Signatures component does not support selecting certificates.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFSignatureCertificateSelectionMode signatureCertificateSelectionMode;

    Swift

    var signatureCertificateSelectionMode: SignatureCertificateSelectionMode { get }

  • Defines which biometric properties, PSPDFSignatureBiometricProperties, should be stored in a digital signature, if one is created. Defaults to PSPDFSignatureBiometricPropertiesOptionAll.

    Note

    Needs to have Digital Signatures licensed, will be ignored otherwise.

    Declaration

    Objective-C

    @property (nonatomic, readonly) PSPDFSignatureBiometricPropertiesOption signatureBiometricPropertiesOptions;

    Swift

    var signatureBiometricPropertiesOptions: PDFSignatureBiometricProperties.Option { get }

  • Enables natural drawing for signatures. Defaults to true. This is only used when Electronic Signatures is not enabled and Annotations is enabled in your license from before the introduction of Electronic Signatures. For Electronic Signatures, use signatureCreationConfiguration instead.

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL naturalSignatureDrawingEnabled;

    Swift

    var naturalSignatureDrawingEnabled: Bool { get }

  • Configuration for the Electronic Signatures creation UI. Defaults to the default signature creation configuration.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NS_REFINED_FOR_SWIFT PSPDFSignatureCreationConfiguration *signatureCreationConfiguration;

  • The object that loads and saves signature annotations. You can implement a signature store to use your own backend.

    If Electronic Signatures is enabled in your license then this defaults to nil, which means signatures can’t be saved. To enable simple on-device signature storage, set this to an instance of KeychainSignatureStore.

    If Annotations is enabled in your license from before the introduction of Electronic Signatures (and Electronic Signatures is not enabled) then this defaults to an instance of KeychainSignatureStore.

    To remove the UI option to choose whether to save signatures and force them to be saved, change the signatureSavingStrategy property or set this store to nil.

    Read more about signature storage options at https://pspdfkit.com/guides/ios/signatures/signature-storage/

    Declaration

  • If enabled, will request that all thumbnails are pre-cached in PDFViewController’s viewDidAppear:. Defaults to false. It will also result in ThumbnailViewController pre-caching thumbnails in the alternative device orientation. This property being false will not prevent ThumbnailViewController from pre-caching for the current view size when it appears. Set this to true if you want to pre-cache thumbnails if you use the thumbnail view mode a lot.

    Warning

    Does not delete any cache and doesn’t change if set after the controller has been presented.
