Question

I am using NSUserDefaults to store some integer settings for my app, but I want to register default values for these settings, using code like this:

NSDictionary *appDefaults = [[NSDictionary alloc] initWithObjectsAndKeys:(NSInteger)0, @"PMChordColour", (NSInteger)1, @"PMTextColour", (NSInteger)0, @"PMBackgroundColour", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:appDefaults];

The values are read in my app using

NSInteger setColour = [[NSUserDefaults standardUserDefaults] integerForKey:@"PMChordColour"];

The problem with this is that NSDictionary does not allow scalar values to be stored.

Is there any way of registering defaults that allows integers to be stored? I realise that I could use NSNumber but it seems like unnecessary overhead.

No, you have to use NSNumber. It’s necessary overhead.
