我在iOS7上发生崩溃.该应用程序是针对6.1 sdk编译的.我无法自己复制,但是我可以从崩溃报告中看到,这是一些用户发生的.问题是堆栈跟踪中没有用户代码,因此难以追踪：
Exception Type: EXC_BAD_ACCESS Code: KERN_INVALID_ADDRESS at 0x13 0 libobjc.A.dylib objc_msgSend + 5 1 UIKit -[UIApplication sendAction:to:from:forEvent:] + 90 2 UIKit -[UIApplication sendAction:toTarget:fromSender:forEvent:] + 30 3 UIKit -[UIControl sendAction:to:forEvent:] + 44 4 UIKit -[UIControl _sendActionsForEvents:withEvent:] + 374 5 UIKit -[UIControl touchesEnded:withEvent:] + 590 6 UIKit -[UIWindow _sendtouchesForEvent:] + 528 7 UIKit -[UIWindow sendEvent:] + 832 8 UIKit -[UIApplication sendEvent:] + 196 9 UIKit _UIApplicationHandleEventQueue + 7096 10 ... CoreFoundation __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 14 16 UIKit UIApplicationMain + 1136
我尝试启用僵尸并在应用程序中执行各种操作,但没有标记任何内容.
更新
我认为这可能已经演变成iOS 7.1下的[UIPickerView _updateSelectedRows],EXC_BAD_ACCESS.我会进一步调查.

解决方法
我有几乎相同的崩溃日志与我们的项目,我们能够跟踪一个动画.
问题是我们在屏幕上和屏幕上动画了一个UIPickerView.如果在动画过程中弹出并处理了拥有UIPickerView的ViewController.我们通过从动画完成块中的超级视图中删除UIPickerView来解决这个问题.

[UIView animateWithDuration：0.5f动画：^ {//设置PickerView的目标帧}完成：^(BOOL完成){[self.pickerView removeFromSuperview];}];
