Using NSUserDefaults
This will go over a quick run through of using NSUserDefaults. This is the class to use to save user preferences for example. It is pretty straight forward.
Saving Data
This is how you save data.
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; // saving a string [prefs setObject:@"test" forKey:@"stringVal"]; // saving a int [prefs setObject::23 forKey:@"intVal"]; // saving it all [prefs synchronize];
Loading Data
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; // getting the string stringVal = [prefs stringForKey:@"stringVal"]; // getting the int intVal = [prefs integerForKey:@"intVal"];
That is it.. pretty simple.
