@interface PSPDFPageLabelView : PSPDFLabelView <PSPDFOverridable>

    Swift

    class PageLabelView : PDFLabelView, Overridable

    Declaration

    Objective-C

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

    Swift

    class PDFPageView : UIView, RenderTaskDelegate, ResizableViewDelegate, Overridable

  • 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

  • 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

  • Handles text and image selection on a page.

    Note

    Requires the Features.textSelection feature flag.

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

    The selection color is determined by the tintColor property inherited from UIView. On Mac Catalyst, the tintColor is set to [NSColor selectedContentBackgroundColor] & unemphasizedSelectedContentBackgroundColor, depending if the current window is the key window or not.

    Declaration

    Objective-C

    
@interface PSPDFTextSelectionView
    : UIView <AVSpeechSynthesizerDelegate, PSPDFOverridable>

    Swift

    class TextSelectionView : UIView, AVSpeechSynthesizerDelegate, Overridable

  • 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.
