Core data not saving my data

Question

I\'m using core data to save some integer (rate) and then I call save in the context:

HeartRateBeat * beat = [HeartRateBeat heartRateWithHeartRate:rate
              


        

Answer 1

I get the same problem but I think its just because, I assume, like me you are just stopping the app through xcode and not actually closing it down. I use this code to force a write. Im using a UIManagedDocument, shared through appdelegate, rather than setting everything up manually.

NSError *error = nil;

if (![self.managedObjectContext save:&error]) {
    NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
    abort();
}

[[AppDelegate sharedAppDelegate].userDatabase saveToURL:[AppDelegate sharedAppDelegate].userDatabase.fileURL forSaveOperation:UIDocumentSaveForOverwriting completionHandler:nil];
