상위 ViewController 가져오기
UIViewController *vc; vc = (UIViewController*)[btn.superview nextResponder]; vc = (UIViewController*)[view.superview nextResponder];
nextResponder
Returns the receiver's next responder, or nil if it has none.
- (UIResponder *)nextResponder
Return Value
The next object in the responder chain to be presented with an event for handling.
Discussion
The UIResponder class does not store or set the next responder automatically, instead returning nil by default. Subclasses must override this method to set the next responder. UIViewimplements this method by returning the UIViewController object that manages it (if it has one) or its superview (if it doesn’t); UIViewController implements the method by returning its view’s superview; UIWindow returns the application object, and UIApplication returns nil.
Availability
- Available in iOS 2.0 and later.
