Some handy NSUserDefaults macros/functions

Some handy NSUserDefaults helper

This helper make it easy to store, fetch and observe values in the NSUserDefaults. I first discovered them in kod and now use it in Justnotes as well.

Show me some code.

Alright. How did you register default values the old way?

NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults];
NSDictionary *defaults = [NSDictionary dictionaryWithObjectsAndKeys: @"[e-mail]", @"user/email"];
[standardUserDefaults registerDefaults:defaults]

Now, do it the easy way.

defaults_init( @{ @"user/email"  : @"[e-mail]" });

Isn't that nice and much shorter? Let's take a look at more examples.

// Set
defaults_set_object(@"user/username", @"Matthias");
defaults_set_object(@"user/logged-in", @(YES));
	
// Get
NSString *email = defaults_object(@"user/email");
NSString *username = defaults_object(@"user/username");
BOOL loggedIn = [defaults_object(@"user/logged-in") boolValue];

What's also nice is that you can observe a value and get a callback when it changed.

defaults_observe(@"user/email", ^(NSString *email){
    ...
});

Unit Tests

The shell script run_unit_tests includes some basic unit tests. You can run them by executing sh run_unit_tests and without involving Xcode.
