Question

I am trying to save my NSUserDefaults when the viewWillDisappear is called on one of my subviews. I can confirm it is getting called.

NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];

[defaults setObject:@"test" forKey:@"123"];

[defaults synchronize];

However whenever I restart the app and try to use it:

NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];

if (![defaults objectForKey@"test"])
    NSLog(@"did not exist");
else 
    NSLog(@"found it");

it never finds it. Why?

Answer 1

You are swapping your key and object. It should be:

if (![defaults objectForKey@"123"])
