알림 센터의 NSTimer 스톱워치

Question

NSTimer에 문제가 있고 알림 센터에 스톱워치를 추가하고 있습니다. Obj C에 익숙하지 않고 Xcode를 사용하지 않습니다. 위젯은 컴파일되고 정상적으로 실행되지만 "시작 :"을 누르면 아무것도 수행되지 않고 00.00.00도 없습니다.

미리 감사드립니다.

[self.stopWatchTimer fire]; 

는 "아무 00.00 없습니다에 의해 당신이 무슨 뜻인지 몰라 : 당신은 NSTimer를 작성 후이기 때문에 그것은 아마 엉망처럼 보인다 ..

Answer 1

난 당신이 줄을 누락 생각합니다. 00 " 그래도.

편집 : 미안합니다. scheduledTimerWithTimeInterval을 수행하면 "불"을 호출 할 필요가 없습니다. 하지만 선택자는 서명을해야합니다 (귀하의 경우) :

- (void)updateTimer:(NSTimer*)theTimer { 
... 
} 
self.stopWatchTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/10.0 
                  target:self 
                 selector:@selector(updateTimer:) 
                 userInfo:nil 
                  repeats:YES]; 

타이머는 그 메시지에서 자신을 보냅니다. 시도해 봐.
