UIAlertView button action?

Question

I have an UIAlertView that shows with this code that asks you to rate the application in the appstore.

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Rate on the Appstore!" 
                                                message:@"" 
                                               delegate:self 
                                      cancelButtonTitle:@"Later" 
                                      otherButtonTitles:@"OK", nil];
[alert show];
[alert release];

But I cannot figure out how to add an action to the OK button that takes you to the app in the AppStore.

Answer 1

How about this?

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex != [alertView cancelButtonIndex]) {
        NSLog(@"Launching the store");
        //replace appname with any specific name you want
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms://itunes.com/apps/appname"]];
    } 
}

Answer 2

You want something like the following:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        NSLog(@"Clicked button index 0");
        // Add the action here
    } else {
        NSLog(@"Clicked button index other than 0");
        // Add another action here
    }
}

NSLog's appear in the console when you press a button and help out whenever you want to debug/test anything.

Then for the action that you want, you'd write something like:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"url_to_app_store"]];
