    // 创建一个UIActionSheet
    UIActionSheet* sheet = [[UIActionSheet alloc]
                            initWithTitle:@"请确认是否删除" // 指定标题
                            delegate:self // 指定该UIActionSheet的委托对象就是该控制器自身
                            cancelButtonTitle:@"取消" // 指定取消按钮的标题
                            destructiveButtonTitle:@"确定" // 指定销毁按钮的标题
                            otherButtonTitles:@"按钮一", @"按钮二", nil]; // 为其他按钮指定标题
    // 设置UIActionSheet的风格
    sheet.actionSheetStyle = UIActionSheetStyleAutomatic;
    [sheet showInView:self.view];
    
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    // 使用UIAlertView来显示用户单击了第几个按钮
    UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"提示"
                         message:[NSString stringWithFormat:@"您单击了第%ld个按钮" , (long)buttonIndex]
                         delegate:nil
                         cancelButtonTitle:@"确定"
                         otherButtonTitles: nil];
    [alert show];
}

@end
