2,316 PointsNot sure how to initialize key-value pairs
It wants me to allocate memory and initialize the key value pairs, but I can't find the proper way to do so. Thanks in advance.
NSMutableDictionaruy *carDict = [[NSMutableDictionary alloc] @"Make":@"Honda", @"Model":@"Accord", nil];

28,883 PointsYou're almost there! Your alloc is correct; you just need to correct the format you're using to initialize the NSMutableDictionary.
The general format for allocating and initializing an NSMutableDictionary object can look like this:
NSMutableDictionary *carDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: /*OBJECT 1*/, /*KEY 1*/, /*OBJECT 2*/, /*KEY 2*/, nil];
In this case, OBJECT 1 would be @"Honda", KEY 1 would be @"Make", OBJECT 2 would be @"Accord", and KEY 2 would be @"Model".
I hope this helps!
