Question

Hey, I am trying to cache info on my IPhone App, but don’t even know where to get started, I would to just cache a string (ex: 123123-12313123-1231231-123123), so when the user comes back it will remember it.

Is there a tutorial I can follow some where or could someone provide me some code?

Thanks

Answer 1

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setString:@"123123123" forKey:@"myKey"];
[userDefaults synchronize];

Later, when you wish to retrieve this object:

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSString *myString = [userDefaults stringForKey:@"myKey"];

You’ll, of course, want to manage the keys properly, etc.
