IOS 5.1 ARC 인식 할 수없는 선택기 인스턴스로 보냈습니다

Question

비슷한 질문을 찾고 있었지만 문제가 무엇인지 알아낼 수 없었습니다. 작동해야하지만 오류가 있습니다.

IOS 5.1 Ipad Stortyboard 응용 프로그램에서 사용자가 팝업보기를 클릭하면 열어야하는 오른쪽 탐색 모음 항목이 있습니다. 그래서 나는 그것이 나에게주는 이제 새로운 팝 오버 클래스 다음 나는 기능을 다음과 같은 시도했지만 아무도 지금까지 일을하지 않았다

-[UIButton view]: unrecognized selector sent to instance 0xa17ba80 
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIButton view]: unrecognized selector sent to instance 0xa17ba80' 

오류로 대체 내가 일하는 팝 오버보기를했지만, 디자인은 좋지 않았다. 코드를 변경하면 비슷한 오류가 발생합니다.

- (IBAction)setColorButtonTapped:(id)sender{ 
- (void)setColorButtonTapped:(id)sender{ 
- (IBAction)setColorButtonTapped:(id)sender forEvent:(UIEvent*)event { 
- (void)setColorButtonTapped:(id)sender forEvent:(UIEvent*)event { 

그리고 당연히 나는 IBAction를 또는 무효

[backButton2 addTarget:self action:@selector(setColorButtonTapped:) forControlEvents:UIControlEventTouchUpInside];

도움이 많이 감사

Answer 1

당신의있는 CustomView로 UIButton를 사용을 감사 a UIBarButtonItem. 이것은 문제 일 수 있습니다. 대신 UIBarButtonItem의 initWithImage:style:target:action: 이니셜 라이저를 사용하는 것이 좋습니다.

Answer 2

UIButton은 뷰이므로 뷰 속성 또는 인스턴스 메서드가 없습니다.
