Question

我正在处理Touches个代表和UITapGestureRecognizer进行单击。以下是方法。当我点击我的视图时，我会按TouchesBegan，SingleTap和TouchesEnded的顺序获得三个事件。当我检测到TouchesEnded时，是否有停止SingleTap事件？ Basicaaly如果TouchesEnded没有发生，我不想在TouchesMoved执行任务。我使用SingleTap中的failTouchEnded BOOL变量并在TouchesEnded中检查它，但不确定它是否是个好主意！

   - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    }

    - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
          failTouchEnded = NO;
    }

    - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
          if(failTouchEnded) return;

    }

    - (void)GestureView:(GestureView*)view handleSignleTap:(UITapGestureRecognizer*)recognizer {
          failTouchEnded = YES;
    }

Answer 1

gestureRecognizer有一个属性cancelsTouchesInView。如果是（这是默认的），如果手势识别器识别出手势，则取消触摸。所以你会取消触摸而不是触摸结束。如果不是，则应将delayedTouchesEnded设置为YES
