User Preferences in Objective-C (iOS) - NSUserDefaults

This post is about how to handle user preferences in iOS. User preferences is needed for storing small amounts of data locally and can work out as a small database for your app where you can store simple stuff like score and etc. This is all done via NSUserDefault class. Examples:


Fetching preferences


NSUserDefaults *settings = [NSUserDefaults standardUserDefaults];
NSString *myParam = [settings stringForKey : @"MY_PARAM"];

Storing preferences


NSUserDefaults *settings = [NSUserDefaults standardUserDefaults];
[settings setObject : strMyParam forKey : @"MY_PARAM"];
[settings synchronize];

Enjoy :)
