NSUserDefaults not saving

Question

I am having a problem in my sprite kit app where my NSUserDefaults variable is not working. In createSceneContents (which I know is being called)

Answer 1

I found another reason why NSUserDefaults not saving,following code can make value in NSUserDefaults not saving:

NSUserDefaults *def= [[NSUserDefaults standardUserDefaults] init];
...
NSUserDefaults *def= [[NSUserDefaults standardUserDefaults] initWithSuiteName:@"123"];

You can search NSUserDefaults in your project to catch those init twice bug.
