Hello everyone,
How would I check in a "if" statement if the NSUserDefault object is saved there or not? I'm not really sure how to call it.. So a pretty short question..
Thanks

A:
if ([[NSUserDefaults standardUserDefaults] objectForKey:@"Foo"] != nil) {
NSLog(@"an object is saved under \"Foo\"!");
}

A:
Dave's answer is correct, but I'd skip the explicit test for nil:
if ([[NSUserDefaults standardUserDefaults] objectForKey:@"Foo"]) {
NSLog(@"An object is saved under \"Foo\"!");
}

It's a style choice. I like to be explicit in my comparisons :)

@Dave DeLong: Absolutely. Mine is a style choice as well, just pointing out an alternative. Consistency is more important. :)
