What are the button indexes in a three-button UIAlertView

The cancel button is always index 0, and all other buttons in the array start at index 1 counting up.

For completion, here’s how to create it:

- (IBAction)showAlert:(id)sender {
    // create an alert view with three buttons
    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Three Button Alert" message:@"This is an alert view with more than two buttons. Will it work?" delegate:self cancelButtonTitle:@"No Way (0)" otherButtonTitles:@"Perhaps (1)", @"Definitely! (2)", nil];
    [alertView show];

And here’s how to react to it:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    switch (buttonIndex) {
        case 0:
            NSLog(@"That was button at index 0");
            case 1:
            NSLog(@"That was button at index 1");
            case 2:
            NSLog(@"That was button at index 2");
            case 3:
            NSLog(@"We don't have a fourth button");

This is a delegate method, so the reacting class needs to conform to the UIAlertView Protocol like so:

@interface ViewController : UIViewController <UIAlertViewDelegate>
