Notes
Some information I have found useful, presented direct from my brain. This is probably more useful to me than to anyone else. I might put it here or as a sub-page (see link to the right).
In progress: Wavelets
Some of the subpages of this category have been moved to posts, as that seems to be a better format.
A Handy Core Data Recipe
- (BOOL) saveObjectContext {
NSError* error;
BOOL wasSuccesful = [objectContext save:&error];
if(!wasSuccesful) {
NSLog(@"Failed to save to data store: %@", [error localizedDescription]);
NSArray* detailedErrors = [[error userInfo] objectForKey:NSDetailedErrorsKey];
if(detailedErrors != nil && [detailedErrors count] > 0) {
for(NSError* detailedError in detailedErrors) {
NSLog(@" DetailedError: %@", [detailedError userInfo]);
}
}
else {
NSLog(@" %@", [error userInfo]);
}
}
return wasSuccesful;
}
