如何比较iOS上的手势类型？
我在一个视图上有三种不同的手势，两种不同的类型。
首先是UITapGestureRecognizer ，另外两个是UILongPressGestureRecognizer 。
长按手势识别器具有不同的minimumPressDuration ，一个是0.15 ，另一个是0.50 ，所以我实现了他的跟随function，以便识别所有手势：
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer: (UIGestureRecognizer *) otherGestureRecognizer{ return true; }
该function允许识别所有手势，但问题是只要识别出UITapGestureRecognizer ，也会识别UITapGestureRecognizer 。
所以，我想知道如何比较gestureRecognizer的类型
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer: (UIGestureRecognizer *) otherGestureRecognizer
或者在检测到UITapGestureRecognizer时如何停止UITapGestureRecognizer ，因为UITapGestureRecognizer触发UITapGestureRecognizer时UILongPressGestureRecognizer触发UILongPressGestureRecognizer 。
而不是在shouldRecognizeSimultaneouslyWithGestureRecognizer:对所有情况返回YES shouldRecognizeSimultaneouslyWithGestureRecognizer:如果你不想同时识别手势，你应该实际返回NO ：
- (BOOL) gestureRecognizer: (UIGestureRecognize *) gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer: (UIGestureRecognizer *) otherGestureRecognizer { return NO; }
但要完成您显然要完成的任务，我建议使用不同的UIGestureRecognizerDelegate方法 – gestureRecognizer:shouldBeRequiredToFailByGestureRecognizer: – 这样您就可以指定哪个手势在另一个之前被识别。 在这种情况下，由于您要在检测到UITapGestureRecognizer时停止UITapGestureRecognizer ，请尝试以下操作：
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { // If the gesture recognizer is a UITapGestureRecongizer, but the other // gesture detected is a UILongPressGestureRecognizer, require the // UITapGestureRecognizer to fail. if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]] && [otherGestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) { return YES; } else { return NO; } }
可以检查UIGestureRecognizer的类
例如：
-(BOOL) gestureRecognizer: (UIGestureRecognize *) gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer: (UIGestureRecognizer *) otherGestureRecognizer { if ([gestureRecognizer isMemberOfClass: [UILongPressGestureRecognizer class]]) { //do stuff } //etc }
