Delegate method called for rightBarButtonItem of UIBarButtonItem
What is the delegate method called when rightBarButtonItem of UIBarButtonItem is tapped? I want to implement a s开发者_高级运维pecific action there.
There is no predefined delegate method. You need to set the delegate/action (similar to a UIControl). For example, create the UIBarButtonItem in viewDidLoad the following way:
self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Mark" style:UIBarButtonItemStylePlain target:self action:@selector(actionForTap:) autorelease];
and implement actionForTap: in your view controller. If you already have the UIBarButtonItem you can set the target/action to those of your desired delegate method, e.g.:
self.navigationItem.rightBarButtonItem.target = self;
self.navigationItem.rightBarButtonItem.action = @selector(actionForTap:);
As a third way, you can configure it in IB (but I'm not going there).
You don't need any delegate method. You can simply use the below code. This is code for simply adding a button on the right and adding an action to that button. In my case I called the method named "AddButtonMethod".
UIBarButtonItem *AddButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(AddButtonMethod:)];
self.navigationItem.rightBarButtonItem = AddButton;
