NSUserDefaults not incrementing

I am trying to increase an NSInteger using NSUserDefaults like this:

NSInteger attempts = [[NSUserDefaults standardUserDefaults]integerForKey:@"tries"];
NSInteger newA = attempts++;
[[NSUserDefaults standardUserDefaults]setInteger:newA forKey:@"tries"];
[[NSUserDefaults standardUserDefaults]synchronize];
NSLog(@"Tries: %d",[[NSUserDefaults standardUserDefaults]integerForKey:@"tries"]);

However this is my NSLogs:

Tries: 0
Tries: 0
Tries: 0
Solution

  • Here is your issue 

    NSInteger newA = attempts++;

    You're incrementing attempts after you set it to newA, try this instead : 

    NSInteger newA = ++attempts;
