默认情况下,加载了传递PKAddPassesViewController.有没有办法知道视图上按下了哪个按钮.

//this method runs when user either click on the cancel or add button

-(void)addPassesViewControllerDidFinish: (PKAddPassesViewController*) controller
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

我想获得按下的按钮的标题PKAddPassesViewController.我已经尝试了下面的代码来访问标题,但我得到了null.

NSLog(@"Title of button    %@",controller.navigationController.navigationItem.rightBarButtonItem.title);
