You're trying to save something into an NSDictionary for a key that's nil, which you can't do.

So:

 NSString *key = nil;
// Cannot add that to an NSDictionary!
NSString *key = @"monkeys";
// Can save this

You need to figure out where you're doing it, and not do it.

	NSString *key = nil;
	// Cannot add that to an NSDictionary!
	NSString *key = @"monkeys";
	// Can save this
