iphone Development - data persistance UI

I have a UILabel that is modified while using my a开发者_StackOverflow中文版pp. I want the text of this UILabel to be saved even after I close the app.

What's the easiest way for doing this?

Save the content when the app is about to quit.

- (void)applicationWillTerminate:(UIApplication *)application
{
    [[NSUserDefaults standardUserDefaults] setObject:label.text forKey:@"label"];
}

And when you create the label, use the saved text.

label.text = [[NSUserDefaults standardUserDefaults] objectForKey:@"label"];

NSUserDefaults will help you with this !
