当设备和模拟器未连接到 Xcode 时，Core Data 崩溃

当连接到 Xcode 时，我的应用程序可以在设备和模拟器中运行。否则它会在此时崩溃（在没有 Xcode 的情况下运行时在两个设备/模拟器上）。一定是调试器让它保持活动状态或者什么的。我认为崩溃来自：

CDObject * cdObject = [NSEntityDescription insertNewObjectForEntityForName:@"CDObject" inManagedObjectContext:self.moc];

我在程序的其他地方使用了核心数据，并且它工作正常。我已经通过 NSLog 语句验证 self.moc 不为零。这是崩溃报告的一部分..

My app runs on both the device and in simulator when connected to Xcode. Other wise it crashes at this point (On both device / simulator when run without Xcode). Must be the debugger keeping it alive or something. I think the crash is coming from:

CDObject * cdObject = [NSEntityDescription insertNewObjectForEntityForName:@"CDObject" inManagedObjectContext:self.moc];

I use Core Data else where in the program and it is working fine.
I've verified that the self.moc is not nil through NSLog statements. Here is part of the crash report..
