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，但只有两次），而且只有当它没有从 Xcode 运行时。
发生的情况是，有时我可以通过从多任务中关闭应用程序，再次打开它，快速锁定屏幕并解锁屏幕来重现错误。
我有时也会遇到不同的错误。

另外我认为它与此方法有关： - [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。
只是为了更容易，UIManagedDocument 单例代码 openWithCompletionHandler 调用了两次并崩溃不是问题，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，并没有改变任何东西。
对于信息量，我很抱歉，但我确实尝试在这里只写最相关的信息，也只写我发现的每种类型的错误。
谢谢您的帮助。
