PSPDFViewControllerDelegate

Objective-C

@protocol PSPDFViewControllerDelegate <NSObject>

Swift

protocol PDFViewControllerDelegate : NSObjectProtocol

Implement this delegate in your UIViewController to get notified of PDFViewController events.

  • Asks the delegate if the specified document should be saved with the provided options.

    This delegate method is not called if the Document being shared has its annotationSaveMode set to disabled.

    Note

    This method will only be called if the view controller’s PSPDFConfiguration autosave option is set to YES, and its annotation save mode is set to a value other than PSPDFAnnotationSaveModeDisabled.

    Declaration

    Objective-C

    - (BOOL)pdfViewController:(nonnull PSPDFViewController *)pdfController
       shouldSaveDocument:(nonnull PSPDFDocument *)document
              withOptions:(NSDictionary<PSPDFDocumentSaveOption, id> *_Nonnull
                               *_Nonnull)options;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldSave document: Document, withOptions options: AutoreleasingUnsafeMutablePointer<NSDictionary>) -> Bool

    Parameters

    pdfController

    The PSPDFViewController instance.
    document

    The document to save.
    options

    The current options that the document is going to be saved with. This is an inout parameter.

    Return Value

    BOOL indicating whether the passed document should be saved with the passed parameters.

  • Notifies the delegate that the specified document’s saving operation was completed.

    Note

    This method will only be called if the view controller’s PSPDFConfiguration autosave option is set to YES, and its annotation save mode is set to a value other than PSPDFAnnotationSaveModeDisabled.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
          didSaveDocument:(nonnull PSPDFDocument *)document

    pdfController

    The PSPDFViewController instance.
    document

    The document that was saved.
    error

    The error that occurred during document saving, if any. Can be nil.

  • Will be called when an action tries to change the document (For example, a PDF link annotation pointing to another document). Will also be called when the document is changed via using the document property. Return NO to block changing the document.

    Declaration

    Objective-C

    - (BOOL)pdfViewController:(nonnull PSPDFViewController *)pdfController
     shouldChangeDocument:(nullable PSPDFDocument *)document;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldChange document: Document?) -> Bool

  • Will be called after the document has been changed.

    Note

    This will also be called for nil and broken documents. use document.isValid to check.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
        didChangeDocument:(nullable PSPDFDocument *)document;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, didChange document: Document?)

  • Called when a page view schedules a render task to update its content view.

    Once the render tasks completes, pdfViewController:didFinishRenderTaskForPageView: will be called.

    See

    pdfViewController:didFinishRenderTaskForPageView:

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
    willScheduleRenderTaskForPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, willScheduleRenderTaskFor pageView: PSPDFPageView)

    Parameters

    pdfController

    The pdf view controller the page view belongs to.
    pageView

    The page view that scheduled the render task.

  • Called when a render task finishes that was scheduled by a page view to update its content view.

    See

    pdfViewController:willScheduleRenderTaskForPageView:

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
    didFinishRenderTaskForPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, didFinishRenderTaskFor pageView: PSPDFPageView)

    Parameters

    pdfController

    The pdf view controller the page view belongs to.
    pageView

    The page view that scheduled the render task.

  • Called when a page view sets an image on its content view. This image can either be a full sized image, a smaller image that is used while waiting for a full sized image, or nil. The image might be acquired from the cache or from a render task.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
    didUpdateContentImageForPageView:(nonnull PSPDFPageView *)pageView
                       isPlaceholder:(BOOL)placeholder;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, didUpdateContentImageFor pageView: PSPDFPageView, isPlaceholder placeholder: Bool)

    Parameters

    pdfController

    The pdf view controller the page view belongs to.
    pageView

    The page view that updated its content view’s image.
    placeholder

    YES if the image set in the content view is just a placeholder while waiting for a full resolution image from the render engine. The placeholder image might also be nil.

  • Called before a page view enters the visible screen area.

    You can use this method to customize the page view before it is displayed. Say, for example, you’ve built a custom user interface for searching, you can use this method to add the search highlights to the page before it comes on screen.

    This call is bound to the page view’s spread view and will be triggered before the spread view enters the visible screen area. As such, you should generally avoid to begin view animations on the page in this callback: CoreAnimation may skip the animation of off-screen elements. If you want to animate changes to the page’s view hierarchy, have a look at PSPDFDocumentViewControllerSpreadIndexDidChangeNotification instead.

    This call will not be invoked for page views belonging to spreads that have an active first responder. This matches the behavior of similar UICollectionViewDelegate callbacks.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
    willBeginDisplayingPageView:(nonnull PSPDFPageView *)pageView
                 forPageAtIndex:(NSInteger)pageIndex;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, willBeginDisplaying pageView: PSPDFPageView, forPageAt pageIndex: Int)

    Parameters

    pdfController

    The pdf view controller the page view belongs to.
    pageView

    The page view that is about to enter the visible screen.
    pageIndex

    The page index of the page that this page view will display.

  • Called when a page view exits the visible screen area.

    This call is bound to the page view’s spread view and will be triggered when the spread view leaves the visible screen area.

    This call will not be invoked for page views belonging to spreads that have an active first responder. This matches the behavior of similar UICollectionViewDelegate callbacks.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
    didEndDisplayingPageView:(nonnull PSPDFPageView *)pageView

                   atRect:(CGRect)rect
               onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldSelectText text: String, with glyphs: [PSPDFGlyph], at rect: CGRect, on pageView: PSPDFPageView) -> Bool

  • Called after text has been selected. Will also be called when text has been deselected. Deselection sometimes cannot be stopped, so the shouldSelectText: will be skipped.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
            didSelectText:(nonnull NSString *)text
               withGlyphs:(nonnull NSArray<PSPDFGlyph *> *)glyphs
                   atRect:(CGRect)rect
               onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, didSelectText text: String, with glyphs: [PSPDFGlyph], at rect: CGRect, on pageView: PSPDFPageView)

  • Called before the menu for text selection is displayed. All coordinates are in view coordinate space.

    Using PSPDFMenuItem will help with adding custom menu’s w/o hacking the responder chain. Default returns menuItems if not implemented. Return nil or an empty array to not show the menu.

    Use PSPDFMenuItem’s identifier property to check and modify the menu items. This string will not be translated. (vs the title property)

    rect is in the coordinate space of the pageView. annotationRect or textRect is in the PDF coordinate space of the current page.

    Declaration

    Objective-C

    - (nonnull NSArray<PSPDFMenuItem *> *)
        pdfViewController:(nonnull PSPDFViewController *)pdfController
      shouldShowMenuItems:(nonnull NSArray<PSPDFMenuItem *> *)menuItems
    atSuggestedTargetRect:(CGRect)rect
          forSelectedText:(nonnull NSString *)selectedText
                   inRect:(CGRect)textRect
               onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldShow menuItems: [PSPDFMenuItem], atSuggestedTargetRect rect: CGRect, forSelectedText selectedText: String, in textRect: CGRect, on pageView: PSPDFPageView) -> [PSPDFMenuItem]

  • Called before the menu for a selected image is displayed.

    Declaration

    Objective-C

    - (nonnull NSArray<PSPDFMenuItem *> *)
        pdfViewController:(nonnull PSPDFViewController *)pdfController
      shouldShowMenuItems:(nonnull NSArray<PSPDFMenuItem *> *)menuItems
    atSuggestedTargetRect:(CGRect)rect
         forSelectedImage:(nonnull PSPDFImageInfo *)selectedImage
                   inRect:(CGRect)textRect
               onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldShow menuItems: [PSPDFMenuItem], atSuggestedTargetRect rect: CGRect, forSelectedImage selectedImage: PSPDFImageInfo, in textRect: CGRect, on pageView: PSPDFPageView) -> [PSPDFMenuItem]

  • Called before we’re showing the menu for an annotation. If annotation is nil, we show the menu to create new annotations (in that case annotationRect will also be nil) This delegate is also called as you dig into sub-menus like the color options.

    Note

    You should create the return value by filtering out unwanted menu items from the suggested menuItems. If you ignore the suggested menuItems, you might break functionality unless you explore every annotation type and every sub-menu and very carefully allow all entries. The identifier property of the PSPDFMenuItem object is not localized and perfect for comparison.

    Declaration

    Objective-C

    - (nonnull NSArray<PSPDFMenuItem *> *)
        pdfViewController:(nonnull PSPDFViewController *)pdfController
      shouldShowMenuItems:(nonnull NSArray<PSPDFMenuItem *> *)menuItems
    atSuggestedTargetRect:(CGRect)rect
           forAnnotations:(nullable NSArray<PSPDFAnnotation *> *)annotations
                   inRect:(CGRect)annotationRect
               onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldShow menuItems: [PSPDFMenuItem], atSuggestedTargetRect rect: CGRect, for annotations: [Annotation]?, in annotationRect: CGRect, on pageView: PSPDFPageView) -> [PSPDFMenuItem]

  • Called before an annotation view is created and added to a page. Defaults to YES if not implemented.

    Warning

    This will only be called for annotations that render as an overlay (that return YES for isOverlay) If NO is returned, viewForAnnotation will not be called.

    Declaration

    Objective-C

    - (BOOL)pdfViewController:(nonnull PSPDFViewController *)pdfController
    shouldDisplayAnnotation:(nonnull PSPDFAnnotation *)annotation
                 onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldDisplay annotation: Annotation, on pageView: PSPDFPageView) -> Bool

  • Delegate for tapping annotations.

    Return YES to override the default action and custom-handle this. Default actions might be scroll to target page, open Safari, show a menu, …

    Some annotations might not have an annotationView attached. (because they are rendered with the page content, for example highlight annotations)

    Note

    This will not fire if you interact with annotation views like the PSPDFGalleryView. See these subclasses for details (e.g. PSPDFMediaPlayerControllerPlaybackDidStartNotification)

    Declaration

    Objective-C

    - (BOOL)pdfViewController:(nonnull PSPDFViewController *)pdfController
       didTapOnAnnotation:(nonnull PSPDFAnnotation *)annotation
          annotationPoint:(CGPoint)annotationPoint
           annotationView:
               (nullable UIView<PSPDFAnnotationPresenting> *)annotationView
                 pageView:(nonnull PSPDFPageView *)pageView
                viewPoint:(CGPoint)viewPoint;

    Parameters

    annotationPoint

    the point relative to the PSPDFAnnotation, in PDF coordinate space.
    viewPoint

    the point relative to the PDFPageView.

  • Called before an annotation will be selected. (but after didTapOnAnnotation:)

    Declaration

    Objective-C

    - (nonnull NSArray<PSPDFAnnotation *> *)
          pdfViewController:(nonnull PSPDFViewController *)pdfController
    shouldSelectAnnotations:(nonnull NSArray<PSPDFAnnotation *> *)annotations
                 onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, shouldSelect annotations: [Annotation], on pageView: PSPDFPageView) -> [Annotation]

  • Called after an annotation has been selected by a touch directly on the page view.

    Note that this method isn’t called for indirect selections, for example when a newly created annotation is selected, a set of annotations are selected using the selection tool, or an annotation is selected via the list of annotations.

    For exact diff tracking, consider using the didSelectAnnotations: and didDeselectAnnotations: subclass hooks of PDFPageView.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
     didSelectAnnotations:(nonnull NSArray<PSPDFAnnotation *> *)annotations
               onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, didSelect annotations: [Annotation], on pageView: PSPDFPageView)

  • Called after an annotation has been deselected by a touch directly on the page view.

    Note that this method isn’t called for indirect selections, for example when a newly created annotation is selected, a set of annotations are selected using the selection tool, or an annotation is selected via the list of annotations.

    For exact diff tracking, consider using the didSelectAnnotations: and didDeselectAnnotations: subclass hooks of PDFPageView.

    Declaration

    Objective-C

    - (void)pdfViewController:(nonnull PSPDFViewController *)pdfController
    didDeselectAnnotations:(nonnull NSArray<PSPDFAnnotation *> *)annotations
                onPageView:(nonnull PSPDFPageView *)pageView;

    Swift

    optional func pdfViewController(_ pdfController: PDFViewController, didDeselect annotations: [Annotation], on pageView: PSPDFPageView)

  • Customization point to modify or replace the view for showing an annotation.

    The default view PSPDFKit would use is passed into this method as annotationView. This view can be modified and then returned, or you can return an entirely different view. For custom annotations types, the passed in annotationView will be nil. You probably don’t want to return nil from this method because that will result in the annotation disappearing when PSPDFKit tries to put it in the annotation view. If you don’t need any customizations for a particular annotation, return annotationView without modifying it.

    To get the targeted rect use annotation.boundingBox(forPageRect: pageView.bounds).

    Declaration

    Objective-C

    - (nullable UIView<PSPDFAnnotationPresenting> *)
    pdfViewController:(nonnull PSPDFViewController *)pdfController
       annotationView:

    annotationView

    The proposed view for displaying the annotation.
    annotation

    The annotation to be displayed.
    pageView

    The view for the page the annotation is on.

    Return Value

    The view for displaying the annotation.

  • Invoked prior to the presentation of the annotation view: use this to configure actions etc

    Warning

    This will only be called for annotations that render as an overlay (that return YES for isOverlay) PSPDFLinkAnnotations are handled differently (they don’t have a selected state) - delegate will not be called for those.

    Declaration

    Objective-C
