我遇到了一个非常奇怪的行为，我的应用程序几乎只在设备上崩溃(我确实设法在模拟器上重现了这个错误，但只重现了两次)，而且只有在它不是从 Xcode 运行时才崩溃。
有时，我可以通过从多任务中关闭应用程序、再次打开它、快速锁定屏幕和解锁屏幕来重现错误。
有时我也会遇到不同的错误。

另外我觉得跟这个方法有关系: - [UIManagedDocument openWithCompletionHandler:] 因为如果我注释掉这一行(用于在 document.documentState == UIDocumentStateClosed 时打开文档)，崩溃就会停止。
为了方便起见，UIManagedDocument Singleton Code openWithCompletionHandler called twice and crashes不是问题，因为 - [UIManagedDocument openWithCompletionHandler:] 没有被调用两次。 另外，可以肯定的是，我确实尝试了该解决方案，但没有改变任何东西。
对于信息量，我很抱歉，但我确实尝试只在这里写下最相关的信息，而且我发现的每种错误类型也只写了一个。
感谢您的帮助。
