What's the easiest way to persist data in an iPhone app?

Question

I want to persist a very simple string. For example "abc". What's the easiest way to do this? I don't want to use a SqlLite database.

Answer 1

If it is just one single string NSUserDefaults is probably the easiest way.

// write
[[NSUserDefaults standardUserDefaults] setObject:@"abc" forKey:@"MY_PERSISTENT_KEY"];

// read
NSString *abc = [[NSUserDefaults standardUserDefaults] valueForKey:@"MY_PERSISTENT_KEY"];
