Adding a simple UIAlertView

Question

What is some starter code I could use to make a simple UIAlertView with one "OK" button on it?

Answer 1

When you want the alert to show, do this:

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"ROFL" 
                                                    message:@"Dee dee doo doo." 
                                                    delegate:self 
                                                    cancelButtonTitle:@"OK" 
                                                    otherButtonTitles:nil];
[alert show];

    // If you're not using ARC, you will need to release the alert view.
    // [alert release];

If you want to do something when the button is clicked, implement this delegate method:

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
    // the user clicked OK
    if (buttonIndex == 0) {
        // do something here...
    }
}

And make sure your delegate conforms to UIAlertViewDelegate protocol:

@interface YourViewController : UIViewController <UIAlertViewDelegate>
