How to add to an NSDictionary

Question

I was using a NSMutableArray and realized that using a dictionary is a lot simpler for what I am trying to achieve.

I want to save a key as a NSSt

Answer 1

For reference, you can also utilize initWithDictionary to init the NSMutableDictionary with a literal one:

NSMutableDictionary buttons = [[NSMutableDictionary alloc] initWithDictionary: @{
    @"touch": @0,
    @"app": @0,
    @"back": @0,
    @"volup": @0,
    @"voldown": @0
}];
