NSManagedObjects that I own being released by main.m?

Question

First, in my root view controllers viewDidLoad, I initialize an NSDictionary with arrays of NSManagedObjects, like so:

- (void)viewDidLoad {
    [super viewD         


        

Answer 1

self.tips hasn't been released; the Tip returned by [self.tips objectForKey:categoryNameString] has. It's returning a fault, not an object. Core Data will automatically fault objects when necessary.

Try putting this in when defining your NSFetchRequest:

[fetchRequest setReturnsObjectsAsFaults:NO];
