PSPDFPageView

Objective-C


@interface PSPDFPageView : UIView <PSPDFRenderTaskDelegate,
                                   PSPDFResizableViewDelegate, PSPDFOverridable>

Swift

class PDFPageView : UIView, RenderTaskDelegate, ResizableViewDelegate, Overridable

Display a single PDF page. View is reused. You can add your own views on top of the annotationContainerView (e.g. custom annotations) Events from a attached UIScrollView will be relayed to all visible PSPDFPageView classes.

Show / Destroy a document

  • The attached presentation context.

    Declaration

    Objective-C

    @property (nonatomic, weak, readonly)
    id<PSPDFPresentationContext> _Nullable presentationContext;

    Swift

    weak var presentationContext: PresentationContext? { get }

  • Prepares the PSPDFPageView for reuse. Removes all unknown internal UIViews.

    Declaration

    Objective-C

    - (void)prepareForReuse;

    Swift

    func prepareForReuse()

Internal views and rendering

  • Redraw the renderView (dynamically rendered PDF for maximum sharpness, updated on every zoom level.)

    Declaration

    Objective-C

    - (void)updateRenderView;

    Swift

    func updateRenderView()

  • Redraw renderView and contentView.

    Declaration

    Objective-C

    - (void)updateView;

    Swift

    func update()

  • Returns the existing subview used to display the given annotation — if any.

    This method will neither trigger loading annotations, nor create and insert a view for the given annotation. In addition, it will not return views that are scheduled to be removed.

    Note

    Unless they are currently selected, most annotations are rendered into the page. Whether or not a separate view will be used to display an annotation is controlled through its isOverlay property. In other words: This method always returns nil for annotations that return NO from isOverlay and are not selected.

    Declaration

    Objective-C

    - (nullable UIView<PSPDFAnnotationPresenting> *)annotationViewForAnnotation:
    (nonnull PSPDFAnnotation *)annotation;

    Swift

    func annotationView(for annotation: Annotation) -> (UIView & AnnotationPresenting)?

  • UIImageView displaying the whole document.

    Declaration

    Objective-C

    @property (nonatomic, readonly) UIImageView *_Nonnull contentView;

    Swift

    var contentView: UIImageView { get }

  • UIImageView for the zoomed in state.

    Declaration

    Objective-C

    @property (nonatomic, readonly) UIImageView *_Nonnull renderView;

    Swift

    var renderView: UIImageView { get }

  • Container view for all overlay annotations.

    This is just a named subclass of UIView that will always track the frame of the PSPDFPageView. It’s useful to coordinate this with your own subviews to get the zIndex right.

    Warning

    Most annotations will not be rendered as overlays or only when they are currently being selected. Rendering annotations within the pageView has several advantages including performance or view color multiplication (in case of highlight annotations) The contents of this view are managed. Additional subviews can be added, but they will be removed during page reuse. Subviews should respond to the PSPDFAnnotationPresenting, especially the annotation method.

    Declaration

    Objective-C

    @property (nonatomic, readonly)
    PSPDFAnnotationContainerView *_Nonnull annotationContainerView;

    Swift

    var annotationContainerView: AnnotationContainerView { get }

    Declaration

    Objective-C

    @property (nonatomic, readonly) CGRect visibleRect;

    Swift

    var visibleRect: CGRect { get }

  • Color used to indicate link or form objects.

    Declaration

    Objective-C

    @property (nonatomic, assign, unsafe_unretained, readwrite)
    UI_APPEARANCE_SELECTOR UIColor *highlightColor;

    Swift

    var highlightColor: UIColor { get set }

  • The color displayed on the page view before the PDF page is rendered.

    By default (assigned nil value), this value will be the best guess for the page background color, given the current render options (such as backgroundFill or invertRenderColor).

    This property is intended to be customized via -[PSPDFViewControllerDelegate pdfViewController:didConfigurePageView:forPageAtIndex:], UIAppearance or by subclassing this class.

    Declaration

    @property (nonatomic, assign, unsafe_unretained, readwrite, null_resettable)
    UIColor *placeholderColor;

    Swift

    var placeholderColor: UIColor! { get set }

Coordinate calculations and object fetching

  • The normalized PDF coordinate space of this view’s page. The origin of the space is the bottom-left corner of the displayed content.

    Use this property together with the methods in the UICoordinateSpace protocol to convert between PDF page and view coordinate spaces. For example to find the location of a UITouch in a page’s PDF coordinate space:

    let viewPoint = touch.location(in: pageView)
let pdfPoint = pageView.convert(viewPoint, to: pageView.pdfCoordinateSpace)

    Note

    Important: Rectangles converted with this coordinate space must be well–formed! Do not, for example, try to convert something with a less–than–zero width…

  • Deprecated

    Deprecated in PSPDFKit 9.1 for iOS. Call showMenuForAnnotations:targetRect:option:animated: instead

    Undocumented

    Declaration

    Swift

    func showMenu(for annotations: [Annotation], targetRect: CGRect, allowPopovers: Bool, animated: Bool)

AnnotationViews

  • Associate an annotation with an annotation view

    Declaration

    Objective-C

    - (void)setAnnotation:(nonnull PSPDFAnnotation *)annotation
    forAnnotationView:
        (nonnull UIView<PSPDFAnnotationPresenting> *)annotationView;

    Swift

    func setAnnotation(_ annotation: Annotation, forAnnotationView annotationView: UIView & AnnotationPresenting)

  • Recall the annotation associated with an annotation view

    Declaration

    Objective-C

    - (nullable PSPDFAnnotation *)annotationForAnnotationView:
    (nonnull UIView<PSPDFAnnotationPresenting> *)annotationView;

    Swift

    func annotation(forAnnotationView annotationView: UIView & AnnotationPresenting) -> Annotation?

  • Hit-testing for a single PSPDFPageView. This is usually a relayed event from the parent PSPDFScrollView. Returns YES if the tap has been handled, else NO.

    All annotations for the current page are loaded and hit-tested (except PSPDFAnnotationTypeLink; which has already been handled by now)

    If an annotation has been hit (via [annotation hitTest:tapPoint]; convert the tapPoint in PDF coordinate space via convertViewPointToPDFPoint) then we call showMenuForAnnotation.

    If the tap didn’t hit an annotation but we are showing a UIMenuController menu; we hide that and set the touch as processed.

    Declaration

    Objective-C

    - (BOOL)singleTapped:(nonnull UITapGestureRecognizer *)recognizer;

    Swift

    func singleTapped(_ recognizer: UITapGestureRecognizer) -> Bool

  • Handle long press, potentially relay to subviews.

    Declaration

    Objective-C

    - (BOOL)longPress:(nonnull UILongPressGestureRecognizer *)recognizer;

    Swift

    func longPress(_ recognizer: UILongPressGestureRecognizer) -> Bool

  • Add an annotation to the current pageView. This will either queue a re-render of the PDF, or add an UIView subclass for the matching annotation, depending on the annotation type and the value of isOverlay.

    Note

    In PSPDFKit, annotations are managed in two ways:

    1) Annotations that are fixed and rendered with the page image. Those annotations are PSPDFHighlightAnnotation, PSPDFSquareAnnotation, PSPDFInkAnnotation and more. Pretty much all more or less “static” annotations are handled this way.

    2) Then, there are the more dynamic annotations like PSPDFLinkAnnotation and PSPDFNoteAnnotation. Those annotations are not part of the rendered image but are actual subviews in PSPDFPageView. Those annotations return YES on the isOverlay property.

    This method is called recursively with all annotation types except if they return isOverlay = NO. In case of isOverlay = NO, it will call updateView to re-render the page.

    Warning

    This will not change anything on the data model below. Also add an annotation to the document object.

    Declaration

    Objective-C

    - (void)addAnnotation:(nonnull PSPDFAnnotation *)annotation

    func tappableAnnotations(at viewPoint: CGPoint) -> [Annotation]

  • Same as above, but will be called when we’re detecting a long press.

    Declaration

    Objective-C

    - (nonnull NSArray<PSPDFAnnotation *> *)tappableAnnotationsForLongPressAtPoint:
    (CGPoint)viewPoint;

    Swift

    func tappableAnnotationsForLongPress(at viewPoint: CGPoint) -> [Annotation]

  • Used within tappableAnnotationsAtPoint: to expand the tap point to make tapping objects easier. By default the rect has a size of 30 pixels.

    Declaration

    Objective-C

    - (CGRect)hitTestRectForPoint:(CGPoint)viewPoint;

    Swift

    func hitTestRect(for viewPoint: CGPoint) -> CGRect

  • Can be used for manual tap forwarding.

    Declaration

    Objective-C

    - (BOOL)singleTappedAtViewPoint:(CGPoint)viewPoint;

    Swift

    func singleTapped(atViewPoint viewPoint: CGPoint) -> Bool

  • Called with the set of annotations that are now selected. Can be used to postprocess annotations or enforce user changes.

    Declaration

    Objective-C

    - (void)didSelectAnnotations:(nullable NSArray<PSPDFAnnotation *> *)annotations;

    Swift

    func didSelect(_ annotations: [Annotation]?)

  • Called with the set of annotations that were selected, but are no longer. Can be used to postprocess annotations or enforce user changes.

    Declaration

    Objective-C

    - (void)didDeselectAnnotations:
    (nonnull NSArray<PSPDFAnnotation *> *)annotations;

    Swift

    func didDeselect(_ annotations: [Annotation])

  • Get annotation rect (PDF coordinate space)

    Declaration

    Objective-C

    - (CGRect)rectForAnnotations:(nonnull NSArray<PSPDFAnnotation *> *)annotations;

    Swift

    func rect(for annotations: [Annotation]) -> CGRect

  • Render options that are used for the live-page rendering. (not for the cache) One way to use this would be to customize what annotations types will be rendered with the pdf. See PSPDFRenderOptions for a list of options.

    Declaration

    Objective-C

    - (nonnull PSPDFRenderOptions *)renderOptionsWithZoomScale:(CGFloat)zoomScale
                                                  animated:(BOOL)animated;

    Swift

    func renderOptions(withZoomScale zoomScale: CGFloat, animated: Bool) -> RenderOptions

  • Helper to properly place an annotation.

    Declaration

    Objective-C

    - (void)centerAnnotation:(nonnull PSPDFAnnotation *)annotation
          aroundPDFPoint:(CGPoint)pdfPoint;

    Swift

    func center(_ annotation: Annotation, aroundPDFPoint pdfPoint: CGPoint)

  • Load page annotations from the PDF.

    Declaration

    Objective-C

    - (void)loadPageAnnotationsAnimated:(BOOL)animated
                  blockWhileParsing:(BOOL)blockWhileParsing;

    Swift
