Instance Property

canRedo

A Boolean value that indicates whether the receiver has any actions to redo.

Declaration

@property(readonly) BOOL canRedo;

Discussion

YES if the receiver has any actions to redo, otherwise NO.

Because any undo operation registered clears the redo stack, this method posts an NSUndoManagerCheckpointNotification to allow clients to apply their pending operations before testing the redo stack.
