Saving

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// saving an NSString

[prefs setObject:@"TextToSave" forKey:@"keyToLookupString"];

// saving an NSInteger

[prefs setInteger:42 forKey:@"integerKey"];

// saving a Double

[prefs setDouble:3.1415 forKey:@"doubleKey"];

// saving a Float

[prefs setFloat:1.2345678 forKey:@"floatKey"];

[prefs synchronize];

Retrieving

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// getting an NSString

NSString *myString = [prefs stringForKey:@"keyToLookupString"];

// getting an NSInteger

NSInteger myInt = [prefs integerForKey:@"integerKey"];

// getting an Float

float myFloat = [prefs floatForKey:@"floatKey"];
