UIApplication sendAction：to：from：forEvent：iOS7没有用户代码

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

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];}];
