Question

The following code is saving data and loading, but it doesn’t show the data when loading view controller.It just says label (Xcode default uilabel).
I believe that I have to use synchronize ,but I am not too sure. May someone help me out.

Implementation file:

- (IBAction)minus
{
    mini = mini - 1;
    minus.text = [NSString stringWithFormat:@"%i", mini];
    [[NSUserDefaults standardUserDefaults] setInteger:mini forKey:@"M"];
}

- (void)viewDidLoad
{
    mini = [[NSUserDefaults standardUserDefaults] integerForKey:@"M"];
}

Header file:

IBOutlet UILabel *minus;

Answer 1

Change:

[[NSUserDefaults standardUserDefaults]setInteger:mini forKey:@"M"];

Into:

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setInteger:mini forKey:@"M"];
[prefs synchronize];

And it should work.

And i dont see you setting minus.text in viewdidload.
