PSPDFConfiguration


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

A PSPDFConfiguration defines the behavior of a PSPDFViewController. It uses the builder pattern via PSPDFConfigurationBuilder to create an immutable copy via a block.

Appearance Properties

  • Set a page mode defined in the enum. Defaults to PSPDFPageModeAutomatic. 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 PSPDFPageTransitionScrollContinuous.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFPageMode pageMode;

    Swift

    var pageMode: PSPDFPageMode { get }

  • Defines the page transition. Defaults to PSPDFPageTransitionScrollPerSpread.

    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, use a [PSPDFDispatchQueue.mainQueue async:^{ ... }]; to set. 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 NO.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFPageTransition pageTransition;

    Swift

    var pageTransition: PSPDFPageTransition { get }

  • Shows first document page alone. Defaults to YES.

    Declaration

    Objective-C

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

    Swift

    var isFirstPageAlwaysSingle: Bool { get }

  • Controls whether spreads can grow larger than the actual view.

    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 PSPDFPageTransitionScrollPerSpread or PSPDFPageTransitionScrollContinuous.

    Defaults to PSPDFConfigurationSpreadFittingAdaptive.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFConfigurationSpreadFitting spreadFitting;

    Swift

    var spreadFitting: PSPDFConfigurationSpreadFitting { get }

  • Only useful for PSPDFPageTransitionCurl. Clips the page to its boundaries, not showing a pageCurl on empty background. Defaults to YES. Set to NO if your document is variably sized.

    Declaration

    Objective-C

    @property (readonly, nonatomic) 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 (readonly, nonatomic) 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 PSPDFPageTransitionScrollPerSpread or PSPDFPageTransitionScrollContinuous.

    See

    -[PSPDFStackViewLayout additionalContentInsets]

    Declaration

    Objective-C

    @property (readonly, nonatomic) UIEdgeInsets additionalContentInsets;

    Swift

    var isShadowEnabled: Bool { get }

  • Set default shadowOpacity. Defaults to 0.7.

    Declaration

    Objective-C

    @property (readonly, nonatomic) CGFloat shadowOpacity;

    Swift

    var shadowOpacity: CGFloat { get }

  • Background color behind the page view. Defaults to a dynamic color on iOS 13 and above which matches the current UIUserInterfaceStyle. Falls back to dark gray color on versions prior iOS 13.

    Declaration

    Objective-C

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

    Swift

    var backgroundColor: UIColor { get }

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

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFAppearanceMode allowedAppearanceModes;

    Swift

    var allowedAppearanceModes: PSPDFAppearanceMode { get }

Scroll View Configuration

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

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFScrollDirection scrollDirection;

    Swift

    var scrollDirection: PSPDFScrollDirection { get }

  • Sets the scroll view inset adjustment mode. Defaults to PSPDFScrollInsetAdjustmentFixedElements. This is only evaluated for PSPDFPageTransitionScrollContinuous & PSPDFScrollDirectionVertical.

    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 (readonly, nonatomic)
    PSPDFScrollInsetAdjustment scrollViewInsetAdjustment;

    Swift

    var scrollViewInsetAdjustment: PSPDFScrollInsetAdjustment { get }

  • Minimum zoom scale. Defaults to 1.

    Declaration

    Objective-C

    Swift

    var minimumZoomScale: Float { get }

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

    Declaration

    Objective-C

    @property (readonly, nonatomic) 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 PSPDFAdaptiveConditionalAdaptive, 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 YES or NO values will directly affect how the scroll view behaves, regardless of presentation context.

    Declaration

    Objective-C

    @property (readonly, nonatomic)
    PSPDFAdaptiveConditional documentViewLayoutDirectionalLock;

    Swift

    var documentViewLayoutDirectionalLock: PSPDFAdaptiveConditional { get }

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFTapAction doubleTapAction;

    Swift

    var doubleTapAction: PSPDFTapAction { get }

  • If set to YES, automatically focuses on selected form elements. Defaults to NO.

    Declaration

    Objective-C

    @property (readonly, getter=isFormElementZoomEnabled, nonatomic)
    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 YES.

    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 (readonly, getter=isScrollOnEdgeTapEnabled, nonatomic)
    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 NO to enable very fast browsing through a document.

    This is only effective if scrollOnEdgeTapEnabled is set to YES.

    Note

    This property has no effect if you are using PSPDFPageTransitionCurl.

    Declaration

    Objective-C

    @property (readonly, getter=animateScrollOnEdgeTaps, nonatomic)
    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 YES.

    Note

    This property has no effect if you are using PSPDFPageTransitionCurl.

    Declaration

    Objective-C

    @property (readonly, nonatomic) CGFloat scrollOnEdgeTapMargin;

    Swift

    var scrollOnEdgeTapMargin: CGFloat { get }

Page Actions

  • Set the default link action for pressing on PSPDFLinkAnnotations. Default is PSPDFLinkActionOpenSafari.

    Note

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

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFLinkAction linkAction;

    Swift

    var linkAction: PSPDFLinkAction { get }

  • May be used to customize other displayed menu actions when text is selected. Defaults to PSPDFTextSelectionMenuActionSearch|PSPDFTextSelectionMenuActionDefine|PSPDFTextSelectionMenuActionSpeak|PSPDFTextSelectionMenuActionShare|PSPDFTextSelectionMenuActionCopy|PSPDFTextSelectionMenuActionAnnotationCreation.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFTextSelectionMenuAction allowedMenuActions;

    Swift

    var allowedMenuActions: PSPDFTextSelectionMenuAction { get }

Features

  • Allows text selection. Defaults to YES.

    Note

    Requires the PSPDFFeatureMaskTextSelection feature flag. This implies that the PDF file actually contains text glyphs. Sometimes text is represented via embedded images or vectors, in that case PSPDFKit can’t select it.

    Declaration

    Objective-C

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

    Swift

    var isTextSelectionEnabled: Bool { get }

  • Allows image selection. Defaults to YES.

    Note

    Requires the PSPDFFeatureMaskTextSelection feature flag. This implies that the image is not in vector format. Only supports a subset of all possible image types in PDF.

    Warning

    Will only work if textSelectionEnabled is also set to YES.

    Declaration

    Objective-C

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

    Swift

    var isImageSelectionEnabled: Bool { get }

  • Defines how the text is selected.

    Defaults to PSPDFTextSelectionModeRegular on iOS and PSPDFTextSelectionModeSimple on Mac Catalyst.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFTextSelectionMode textSelectionMode;

    Swift

    var textSelectionMode: PSPDFTextSelectionMode { get }

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

    Setting this to YES will:

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

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

    Defaults NO.

    Declaration

    Objective-C

    @property (readonly, nonatomic) 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.

    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 PSPDFAnnotationStringInk but not PSPDFAnnotationStringSignature, signatures added in previous session will still be editable (since they are Ink annotations). On the other hand, if you set PSPDFAnnotationStringSignature but not PSPDFAnnotationStringInk, then your newly created signatures will not be movable. See PSPDFAnnotation.h for additional comments.

    Declaration

    Objective-C

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

    Swift

    var editableAnnotationTypes: Set<AnnotationString> { 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 (readonly, nonatomic) PSPDFAnnotationType typesShowingColorPresets;

    Swift

    var typesShowingColorPresets: AnnotationType { get }

  • Customize the inspector items globally.

    This currently affects PSPDFAnnotationStyleViewController and PSPDFFreeTextAccessoryView.

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

    See PSPDFAnnotationStyleKey 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 PSPDFConfiguration).

    Declaration

    Objective-C

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

    Swift

    var propertiesForAnnotations: [AnnotationString : Any] { get }

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

    Declaration

    @property (readonly, getter=isFreeTextAccessoryViewEnabled, nonatomic)
    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 PSPDFBookmarkManagerSortOrderPageBased.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFBookmarkManagerSortOrder bookmarkSortOrder;

    Swift

    var bookmarkSortOrder: PSPDFBookmarkManagerSortOrder { get }

  • Sets the page’s bookmark indicator mode. Defaults to PSPDFPageBookmarkIndicatorModeOff. 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 customising the bookmark indicator, see PSPDFBookMarkIndicatorButton.h

    See

    bookmarkIndicatorInteractionEnabled

    Declaration

    Objective-C

    @property (readonly, nonatomic)
    PSPDFPageBookmarkIndicatorMode bookmarkIndicatorMode;

    Swift

    var bookmarkIndicatorMode: PSPDFPageBookmarkIndicatorMode { get }

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

    See

    bookmarkIndicatorMode

    Declaration

    Objective-C

    @property (readonly, nonatomic) BOOL bookmarkIndicatorInteractionEnabled;

    Swift

  • The save method will be invoked when the view controller is dismissed. This increases controller dismissal if enabled.

    Note

    Make sure that you don’t re-create the PSPDFDocument object if you enable background saving, else you might run into race conditions where the old object is still saving and the new one might load outdated/corrupted data. Defaults to NO.

    Declaration

    Objective-C

    @property (readonly, nonatomic) BOOL allowBackgroundSaving;

    Swift

    @property (readonly, nonatomic) 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

Search

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

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFSearchMode searchMode;

    Swift

    var searchMode: PSPDFSearchMode { 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 (readonly, nonatomic) CGFloat searchResultZoomScale;

    Swift

    var searchResultZoomScale: CGFloat { get }
