I've added NSUserDefaults
data retrieval to my app, which is pretty nice. But for testing I would like to reset all the data I added to the defaults database, so that everything is in the state when the user launches the app the first time.
I tried to call:
[NSUserDefaults resetStandardUserDefaults];
but that doesn't do anything. The defaults are still saved and can be retrieved.
You want NSUserDefaults removePersistentDomainForName
. This will remove all user defaults for the application:
NSString *appDomain = [[NSBundle mainBundle] bundleIdentifier];
[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:appDomain];
For more information on the NSUserDefaults
class see the Apple docs.
Alternately, if all you are concerned with is data in the iOS Simulator, you can do that via iOS Simulator > Reset Content and Settings.
