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];

}

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

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

//按钮action
- (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];

}


//立刻载入百度，但是被背景覆盖
- (void)viewDidLoad {
    [super viewDidLoad];
    webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 240, 360)];
    NSURLRequest *request =[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.baidu.com"]];
    [self.view addSubview: webView];
    [webView loadRequest:request];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(void)loadWebPageWithString:(NSString*)urlString{
}

@end

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);
}
