Question

I’ve got a simple UIAlertView showing when user runs the app. It has this structure:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Welcome!", "")
                                                message:NSLocalizedString(@"This is a welcome message.", "")                             
                                               delegate:nil
                                      cancelButtonTitle:@"OK" 
                                      otherButtonTitles: nil];
[alert show];
[alert release];

The question is, How can I customize it to show every 5 runs for example?

Thanks in advance 😉

You can use NSUserDefaults to store app executions count for key AppRunCount (you can introduce your own key name):

int runCount = [[NSUserDefaults standardUserDefaults] integerForKey:@"AppRunCount"] + 1

[[NSUserDefaults standardUserDefaults] setInteger:runCount forKey:@"AppRunCount"];

if (runCount <= 5) {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Welcome!", "")
                                            message:NSLocalizedString(@"This is a welcome message.", "")                             
                                           delegate:nil
                                  cancelButtonTitle:@"OK" 
                                  otherButtonTitles: nil];
    [alert show];
    [alert release];
}

You can just add code above to viewDidLoad
