PSPDFPageView

The view that displays a single PDF page.

You can add your own views, e.g. custom annotation overlays, on top of the annotationContainerView. Events from parent UIScrollView will be relayed to all visible PSPDFPageView classes.

Declaration

Objective-C


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

Swift

class PDFPageView : UIView, RenderTaskDelegate, ResizableViewDelegate, Overridable

PSPDFRelayTouchesView
The user interface view will relay touches of subviews, but won’t react on touches on this actual view itself.

Note
This is achieved with overriding pointInside:withEvent:.
Declaration
Objective-C

@interface PSPDFRelayTouchesView : PSPDFContainerView
Swift

class RelayTouchesView : PDFContainerView
PSPDFContainerView
A container view cannot draw content in itself.

It uses a CATransformLayer as backing. This allows blend mode pass-through, and is more lightweight than a regular view.

Note
UIStackView uses the same trick for being a purely managing container.
Declaration
Objective-C

@interface PSPDFContainerView : UIView
Swift

class PDFContainerView : UIView
PSPDFTextSelectionView
The view that handles text and image selection on a page view.

The color of the selection blocks and handles is determined by tintColor. In apps built with Mac Catalyst, the tint color is set to .selectedContentBackground or .unemphasizedSelectedContentBackground, depending on whether the text selection view’s window is key or not.

Don’t manually initialize this class. The initializer is not exposed.

Declaration
Objective-C

@interface PSPDFTextSelectionView : UIView <AVSpeechSynthesizerDelegate, PSPDFOverridable>
Swift

class TextSelectionView : UIView, AVSpeechSynthesizerDelegate, Overridable
PSPDFStyleButton
Button that can use a modern (blurred) or flat style.

You can use UIAppearance to customize the main properties.
```
[PSPDFStyleButton appearance].buttonStyle = PSPDFButtonStyleFlat;
[PSPDFStyleButton appearance].backgroundColor = [UIColor colorWithWhite:0.1 alpha:0.8];
[PSPDFStyleButton appearance].tintColor = UIColor.whiteColor;
```
Note
The background color can be customized by setting the standard backgroundColor UIView property. If you want to customize the background color, it is recommended that you use PSPDFLabelStyleFlat, as using the blur effect with a non-translucent background color might produce unexpected results.

If you are customizing this view, you might also want to apply similar changes to PSPDFLabelView.
