Pop up a list of options - iPhone SDK

Here's a quick snippet for popping up a list of options using the UIActionSheet in iPhone OS.

What's slightly confusing is that the index of the 'cancelButton' is 1, and 'destructiveButton' is 0, even though 'cancelButton' is listed first in the initWithTitle selector. This gets me each time!


// place this code in a UIViewController subclass

- (void)debugButtonPressed:(id)sender
{
UIActionSheet* action = [[UIActionSheet alloc]
initWithTitle:@"Menu"
delegate:self
cancelButtonTitle:@"Continue"
destructiveButtonTitle:@"Quit"
otherButtonTitles:@"Debug",nil ];
[action showInView:self.view];
[action release];
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
switch (buttonIndex) {
case 0: // Quit
NSLog(@"Quit");
break;
case 1: // Continue
NSLog(@"Continue");
break;
case 2: // Debug
NSLog(@"Debug");
break;
}
}
