    Declaration

    Objective-C

    @property (nonatomic, readonly) NSArray<PSPDFAnnotation *> *_Nonnull annotations;

    Swift

    var annotations: [PSPDFAnnotation] { get }

    Declaration

    Objective-C

    - (BOOL)moveAnnotationAtZIndex:(NSUInteger)sourceIndex
                      toZIndex:(NSUInteger)destinationIndex
                         error:(NSError *_Nullable *_Nullable)error;

    Swift

    func moveAnnotation(atZIndex sourceIndex: UInt, toZIndex destinationIndex: UInt) throws

    Parameters

    sourceIndex

    The index of the PSPDFAnnotation object to be moved.
    destinationIndex

    z-index the annotation should be moved to.

  • Move the annotation by a specified z-index move.

    Declaration

    Objective-C

    - (BOOL)executeZIndexMove:(PSPDFAnnotationZIndexMove)zIndexMove
    forAnnotationAtZIndex:(NSUInteger)soureIndex
                    error:(NSError *_Nullable *_Nullable)error;
