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;

    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

    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)

    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 }

    BOOL formElementZoomEnabled;

    Swift

    var isFormElementZoomEnabled: Bool { get }

  • Tap on begin/end of page scrolls to previous/next page.

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

    See

    scrollOnTapPageEndAnimationEnabled and scrollOnTapPageEndMargin for related properties.

    Defaults to YES.

    Declaration

    Objective-C

    @property (readonly, getter=isScrollOnTapPageEndEnabled, nonatomic)
    BOOL scrollOnTapPageEndEnabled;

    Swift

    var isScrollOnTapPageEndEnabled: Bool { get }

  • Page transition to next or previous page via scrollOnTapPageEndEnabled is enabled. Defaults to NO.

    Note

    This property has no effect if you are using a page curl layout.

    Declaration

    Objective-C

    @property (readonly, getter=isScrollOnTapPageEndAnimationEnabled, nonatomic)
    BOOL scrollOnTapPageEndAnimationEnabled;

    Swift

    var isScrollOnTapPageEndAnimationEnabled: Bool { get }

  • Margin at which the scroll to next/previous tap should be invoked. Defaults to 44.

    Note

    Swift

    var scrollOnTapPageEndMargin: CGFloat { get }

Page Actions

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

    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.

    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.

    Declaration

    Objective-C

    @property (readonly, nonatomic) PSPDFTextSelectionMode textSelectionMode;

    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 with the exception of PSPDFAnnotationStringLink.

    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.

    @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

    Declaration

    Objective-C

    @property (readonly, nonatomic) BOOL allowToolbarTitleChange;

    Swift

    var allowToolbarTitleChange: Bool { get }

  • If YES, the navigation bar will be hidden when the user interface is hidden. If NO, the navigation will stay shown or hidden depending on the value of [UINavigationController navigationBarHidden]. Defaults to YES.

    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 YES, 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.

    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

  • The PDF Specification

    • See

    PDF Reference 1.7, Chapter 13.3 Sounds and PSPDFSoundAnnotation for details.

    Declaration

    Objective-C

    @property (readonly, nonatomic)
    NSDictionary<NSString *, id> *_Nonnull soundAnnotationRecordingOptions;

    Swift

    var soundAnnotationRecordingOptions: [String : Any] { get }

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 }

Signatures

  • Defines if a signature should be saved after creation. Defaults to PSPDFSignatureSavingStrategySaveIfSelected. Shows an action sheet when done creating a signature in PSPDFSignatureViewController, when set to PSPDFSignatureSavingStrategySaveIfSelected.

    Declaration

    Objective-C

    @property (readonly, nonatomic)
    PSPDFSignatureSavingStrategy signatureSavingStrategy;

    Swift

    var signatureSavingStrategy: PSPDFSignatureSavingStrategy { get }

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

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

    Note

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

    Declaration

    Objective-C

    @property (readonly, nonatomic)
    PSPDFSignatureCertificateSelectionMode signatureCertificateSelectionMode;

    Swift

    var signatureCertificateSelectionMode: PSPDFSignatureCertificateSelectionMode { 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 (readonly, nonatomic)
    PSPDFSignatureBiometricPropertiesOption signatureBiometricPropertiesOptions;

    Swift

    var signatureBiometricPropertiesOptions: PSPDFSignatureBiometricPropertiesOption { get }

  • Enables natural drawing for signatures. Defaults to YES.

    Declaration

    Objective-C

    @property (readonly, nonatomic) BOOL naturalSignatureDrawingEnabled;

    Swift

    var naturalSignatureDrawingEnabled: Bool { get }

  • The default signature store implementation. Defaults to PSPDFKeychainSignatureStore.

    Declaration

    Objective-C

    @property (readonly, nonatomic) id<PSPDFSignatureStore> _Nonnull signatureStore;

Sharing

Advanced Properties

  • Enable/Disable all internal gesture recognizers. Defaults to YES. Can be useful if you’re doing custom drawing on the PSPDFPageView.

    Declaration

    Objective-C

    @property (readonly, nonatomic) BOOL internalTapGesturesEnabled;

    Swift

    var internalTapGesturesEnabled: Bool { get }

  • Set this to true to allow this controller to access the parent navigationBar/navigationController to add custom buttons. Has no effect if there’s no parentViewController. Defaults to NO.

    Note

    When using this feature, you should also implement both childViewControllerForStatusBarHidden and childViewControllerForStatusBarStyle to return the PSPDFViewController instance that is embedded.

    Declaration

    Objective-C

    @property (readonly, nonatomic) BOOL useParentNavigationBar;

    Swift

    var useParentNavigationBar: Bool { get }

  • If enabled, will request that all thumbnails are pre-cached in viewDidAppear:. Defaults to NO. Set this to YES if you want to precache 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.

    Declaration

    Objective-C

    @property (readonly, nonatomic) BOOL shouldCacheThumbnails;

    Swift

    var shouldCacheThumbnails: Bool { get }
