问题描述
UITapGestureRecognizer导致应用程序在滑动完成时崩溃。在非常短的距离内完成的滑动不会导致任何问题，但是在较长距离上完成的操作会产生错误：
UITapGestureRecognizer causes app to crash when a swipe is done. Swipes done over very short distances do not cause any problems, but those done over a longer distance give the error :
-[UITapRecognizer name]: unrecognized selector sent to instance 0x17ee27c0
其中0x17ee27c0是随机值。
where 0x17ee27c0 is a random value.
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITapRecognizer name]: unrecognized selector sent to instance 0x17ee27c0'

UITapRecognizer *（0x17ee27c0）来自tapGestureRecognizer._imp
UITapRecognizer * (0x17ee27c0) is from tapGestureRecognizer._imp
这是在运行iOS 8.1的多个设备上发生的。源码是在Xcode 6上编译的。
This is happening on multiple devices running iOS 8.1 . The source is compiled on Xcode 6.
这是我如何声明UITapGestureRecognizer：
Here is how I declare the UITapGestureRecognizer:
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)];
[myView addGestureRecognizer:tapGestureRecognizer];
这里是方法：
- (void)viewTapped:(UITapGestureRecognizer *)sender { }
UITapGestureRecognizer放置在SKView上;
The UITapGestureRecognizer is placed on a SKView;
这里是堆栈跟踪：
推荐答案
我在我的一个SpriteKit游戏中有同样的问题，它是因为你在场景之间的过渡期间使用手势，我解决了它通过设置 gestureRecognizer.enable 属性（）转换为 NO 。
I had the same issue in one of my SpriteKit Games, it is caused when you use gestures during transition between scenes, i solved it by setting gestureRecognizer.enable property (documentation) to NO before the transition.
