One of the first things I do on starting a new AppKit or UIKit project is add a few lines of code to set default values for NSUserDefaults. You’ll never have to check to see if nil was returned from a call to NSUserDefaults once you do this.Add the following snippet to your application delegate’s finished launching method.
1 2 3 4 5 6 NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSURL *url = [[NSBundle mainBundle] URLForResource:@"DefaultDefaults" withExtension:@"plist"]; NSDictionary *d = [NSDictionary dictionaryWithContentsOfURL:url]; if (d) [defaults registerDefaults:d];
Then create a property list called “DefaultDefaults.plist” and add it as a resource. Anytime you add another preference/default to your application, add the default value to this plist.
