iphone Core Data Unresolved error while saving
- by Ahmed Kotb
I am getting a strange error message from the core data when trying to save
but the problem that the error is not reproducible ( it appears at different times when doing different tasks)
the error message:
Unresolved error Domain=NSCocoaErrorDomain Code=1560 UserInfo=0x14f5480 "Operation could not be completed. (Cocoa error 1560.)", {
NSDetailedErrors = (
Error Domain=NSCocoaErrorDomain Code=1570 UserInfo=0x5406d70 "Operation could not be completed. (Cocoa error 1570.)",
Error Domain=NSCocoaErrorDomain Code=1570 UserInfo=0x14f9be0 "Operation could not be completed. (Cocoa error 1570.)"
);
}
and the method that generates the error is:
- (IBAction)saveAction:(id)sender {
NSError *error;
if (![[self managedObjectContext] save:&error]) {
// Handle error
NSLog(@"Unresolved error %@, %@, %@", error, [error userInfo],[error localizedDescription]);
exit(-1); // Fail
}
}
any idea for the reason of this message ? giving that it appears at random times
