여기주셔서 대단히 감사하는 것은 그 추적 데이터가 훨씬 더 지금 포맷의 viewDidLoad
UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc]
initWithTarget:self action:@selector(handleLongPress:)];
lpgr.minimumPressDuration = 0.2; //user needs to press for 2 seconds
[mapView addGestureRecognizer:lpgr];
[lpgr release];
handleLongPress :가 생성 된보기 컨트롤러에서 구현되었음을 확인할 수 있습니까? (initWithTarget : self와 동일한 클래스)? – danh
예. 나는 mapView 있고이 mapView viewdidload있는이 코드가 있습니다. 내가 뭘해야되는거야? 감사합니다 –
