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

To store:

NSString * str = @"name123";
NSUserDefaults *def=[NSUserDefaults standardUserDefaults];
[def setObject:str forKey:@"Key"];
[def synchronize];
NSLog(@"str = = %@",str);

To Retrieve:

NSUserDefaults *def=[NSUserDefaults standardUserDefaults];
NSString *str2 = [def valueForKey:@"Key"];
NSLog(@" Saved str  = = %@",str2);
