展现效果例如以下：

功能说明：

1加入来图片背景，

2动态展现百度网页，

3动态加入button。

4展现提示框。展现你点击提示框得index

 我成功来你也快来试试。

1 详细得项目创建与拖动button到storyboard 就不在详述

 

 storyboard 上加入来button。同一时候也添加来背景。

2 按住ctrl键拖拽到ViewController.m文件空白处，生成someButtonClicked,填充代码后例如以下

-(void)someButtonClicked{//    NSLog(@"点击成功。");    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"                                                    message:@"您点击了动态button！"                                                   delegate:self                                          cancelButtonTitle:@"确定"                                          otherButtonTitles:@"取消",@"点击index",nil];    [alert show];}

3 动态生成button 点击事件（提示框）

- (IBAction)btnTouch:(id)sender {    CGRect frame = CGRectMake(90, 100, 200, 60);        UIButton *someAddButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];        someAddButton.backgroundColor = [UIColor clearColor];        [someAddButton setTitle:@"点击试试看!" forState:UIControlStateNormal];        someAddButton.frame = frame;        [someAddButton addTarget:self action:@selector(someButtonClicked) forControlEvents:UIControlEventTouchUpInside];        [self.view addSubview:someAddButton];}

5 为了知道你点击提示框得那一个index ，添加托付，和实现托付

UIAlertViewDelegate 就是加入托付

6 最后就是实现托付方法。目的就是知道您点击那一个index

//托付-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{    NSLog(@"buttonIndex:%d", buttonIndex);}
