问题
Some users of mine are encountering a CoreData error when performing a save. I haven't been able to find any information online about this error or how to symbolicate the stack trace.
The error message is attempt to recursively call -save: on the context aborted, stack trace, with the full error message below.
Doe anyone have any hints or ideas on how to figure out what is going wrong?

回答1:
I had the same problem with the Xcode8/ios10. The problem was due to a call to save core data context inside the following method.
- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller {
[self methodCallingSaveContext];
}
The
methodCallingSaveContext
calls the save core data context. In order to break the recursive call I rewrote the method in the following way:
- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller {
dispatch_async(dispatch_get_main_queue(), ^{
[self methodCallingSaveContext];
});
}
Now everything is working again.
