    Similar to the other responses, but this is very easy to implement in comparison.

    Make your class use the UIActionSheetDelegate.

    Example:

    @interface ExampleViewController : UIViewController 
    

    Then add to your ExampleViewController.mm/m

    - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex  { //Get the name of the current pressed button 
    NSString *buttonTitle = [actionSheet buttonTitleAtIndex:buttonIndex]; 
    if  ([buttonTitle isEqualToString:@"Remove"]) {
        NSLog(@"Remove this actionSheet"); } 
    if ([buttonTitle isEqualToString:@"Button 1"]) {
        NSLog(@"Button 1 pressed"); } 
    if ([buttonTitle isEqualToString:@"Button 2"]) {
        NSLog(@"Button 2 pressed"); }
    if ([buttonTitle isEqualToString:@"Button 3"]) {
        NSLog(@"Button 3 pressed"); } 
    if ([buttonTitle isEqualToString:@"Cancel"]) {
        NSLog(@"Cancel clicked (anywhere away from it)"); } }
    

    Now in a button pressed event or where/when you want this to popup call the following:

        - (IBAction)aButtonPressed:(id)sender {
         NSString *actionSheetTitle = @"Action Sheet"; // Title 
         NSString *destroyTitle = @"Destroy"; // Button titles
         NSString *button1 = @"Button 1"; 
         NSString *button2 = @"Button 2";
         NSString *button3 = @"Button 3";
         NSString *cancelTitle = @"Cancel"; 
        UIActionSheet *actionSheet = [[UIActionSheet alloc]
                                      initWithTitle:actionSheetTitle
                                       delegate:self
                                       cancelButtonTitle:cancelTitle
                                       destructiveButtonTitle:destroyTitle
                                       otherButtonTitles:button1, button2, button3, nil]; [actionSheet showInView:self.view];
    }
