UIView에서 UIButton 동작과 UITapGestureRecognizer를 구분합니다.

Question

TVAnimationGestures (고급 테이블 뷰)에서 Apple의 WWDC 2010 비디오를 따르고 있습니다. 그들은 머리글의 하위보기로 단추를 사용하여 테이블을 확장하거나 축소합니다. 그런 다음 나중에 강의에서 전체 화면에 탭 제스처를 추가합니다. 그 메커니즘을 제자리에두고 싶습니다. 헤더와 다른 액션이있는 또 다른 버튼이 있습니다. 그러나 디버그 모드에서는 단추를 만든 영역에서도 머리글을 누를 때마다 동작 메서드를 사용할 때 보낸 사람이 항상 UITapGestureRecognizer 인 것처럼 보입니다. 그렇다면 버튼과 헤더의 탭을 구별하기 위해 새로운 액션이나 코드에서 다른 버튼을 추가하는 방법은 무엇입니까? 그 클래스에 대해 아래에 코드를 복사하여 붙여 넣었습니다. shouldReceiveTouch : 당신이 (BOOL)를 구현해야합니다 특정 컨트롤의 제스처 인식기 gestureRecognizer 활성화되지하려면

Answer 1

UIGestureRecognizer의 대리자 메서드, 다음은 어떤 버튼에 대한 인식에서 이벤트를 무시합니다 예를 들어를 그

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch 
{ 


    return !([touch.view isKindOfClass:[UIButton class]]);
