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

Once the render taks completed, 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.
-pdfViewController:didFinishRenderTaskForPageView:
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.




 

-pdfViewController:didUpdateContentImageForPageView:isPlaceholder:

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 aquired 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`.






-pdfViewController:willBeginDisplayingPageView:forPageAtIndex:

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.

Note

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.

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.






-pdfViewController:didEndDisplayingPageView:forPageAtIndex:

Called when a page view exits the visible screen area.

Note

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

Declaration

Objective-C

- (void)pdfViewController:(nonnull PSPDFViewController *)pdfController

Menu Handling






-pdfViewController:shouldShowMenuItems:atSuggestedTargetRect:forSelectedText:inRect:onPageView:

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]






-pdfViewController:shouldShowMenuItems:atSuggestedTargetRect:forSelectedImage:inRect:onPageView:

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]






-pdfViewController:shouldShowMenuItems:atSuggestedTargetRect:forAnnotations:inRect:onPageView:

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 filter out unwanted menu items as a blacklist - if you try to whitelist menu items, you might break functionality, unless you explore every annotation type and every sub-menu and very carefully allow all entries. The idenfifier property of the PSPDFMenuItem object is not loacalized and perfect for comparison.

Declaration

Objective-C

- (nonnull NSArray<PSPDFMenuItem *> *)
        pdfViewController:(nonnull PSPDFViewController *)pdfController
      shouldShowMenuItems:(nonnull NSArray<PSPDFMenuItem *> *)menuItems

Swift

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

Annotations






-pdfViewController:shouldDisplayAnnotation:onPageView:

Called before a 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

-pdfViewController:didTapOnAnnotation:annotationPoint:annotationView:pageView:viewPoint:
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;

Swift

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

-pdfViewController:didSelectAnnotations:onPageView:
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.
