PSPDFBackForwardActionListDelegate

Objective-C

@protocol PSPDFBackForwardActionListDelegate <NSObject>

Swift

protocol BackForwardActionListDelegate : NSObjectProtocol

An object to handle events from a BackForwardActionList.

Implementing one of each of the requestedBackActionExecution and requestedForwardActionExecution methods is required. They are marked optional during the deprecation transitional period.


                      
                      
                      
                      
                      -backForwardList:requestedBackActionExecution:animated:

Should execute the provided back actions in reverse order and also call registerAction: to register the inverse actions.

This method will become required when the deprecated variant without the animated parameter is removed.

Declaration

Objective-C

- (void)backForwardList:(nonnull PSPDFBackForwardActionList *)list
    requestedBackActionExecution:(nonnull NSArray<PSPDFAction *> *)actions
                        animated:(BOOL)animated;

Swift

optional func backForwardList(_ list: BackForwardActionList, requestedBackActionExecution actions: [PSPDFAction], animated: Bool)


                      
                      
                      
                      
                      -backForwardList:requestedForwardActionExecution:animated:

Should execute the provided forward actions in reverse order and also call registerAction: to register the inverse actions.

This method will become required when the deprecated variant without the animated parameter is removed.

Declaration

Objective-C

- (void)backForwardList:(nonnull PSPDFBackForwardActionList *)list
    requestedForwardActionExecution:(nonnull NSArray<PSPDFAction *> *)actions
                           animated:(BOOL)animated;

Swift

optional func backForwardList(_ list: BackForwardActionList, requestedForwardActionExecution actions: [PSPDFAction], animated: Bool)


                      
                      
                      
                      
                      -backForwardListDidUpdate:

Called whenever backList or forwardList get updated.

Declaration

Objective-C

- (void)backForwardListDidUpdate:(nonnull PSPDFBackForwardActionList *)list;

Swift

optional func backForwardListDidUpdate(_ list: BackForwardActionList)
