ViewController *vc;

vc = (ViewController*)[btn.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.
