推荐答案

@Umesh Kumar:是

@Umesh Kumar: YES

最后，事实证明它的导航令人困惑. 这是详细信息:

Finally, it turns out that its the navigation stacks confusion. Here is the detail:

1. 我们都知道默认情况下可以同时执行两个或多个按钮动作.(exclusiveTouch=NO)
2. 有时，当粘贴控制器中的按钮时，这将导致导航键推到下一个控制器，但是人们可能会粘贴导航条左侧的后退按钮，这只会弹出控制器.这将导致导航堆栈混乱.您会看到控制器被推入或弹出来确实很奇怪.
3. 发生这种情况时，总会发生很多奇怪的崩溃，包括我上面所想的崩溃.
4. 请注意，根据我的经验，这仅发生在IOS 7上，而这些崩溃也仅发生在IOS 7上.
5. 因此，我们需要设置button.exclusiveTouch = YES.但是，确实，我真的不知道为什么仅在iOS 7上会发生这种情况.

1. We all know two or more buttons action can be performed at the same time by default.(exclusiveTouch=NO)
2. Sometimes, when a button in you controller be taped which will cause the nav to push to next controller, but people may taped the back button on the left of the navbar which will simply pop the controller. This will cause the navigation stacks confusion. You will see the controller pushed in or poped back really strange.
3. When this happens, there will always be many strange crashes, include the crash I figured above.
4. Note that, According to my experience, This happens on IOS 7 only, and these crashes only happens on IOS 7 too.
5. So, we need to set button.exclusiveTouch = YES.But indeed, i realy do not know why this happens only on IOS 7.
