展现效果如下:

功能说明:

2动态展现百度网页,
3动态添加按钮,
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 具体得项目创建与拖动按钮到storyboard 就不在详述



storyboard 上添加来按钮,同时也增加来背景!

2 按住ctrl键拖拽到ViewController.m文件空白处,生成someButtonClicked,填充代码后如下

-(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];
}


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]; }

//委托 -(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]; }

//立马加载百度,可是被背景覆盖
- (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 ,增加委托,和实现委托



UIAlertViewDelegate 就是添加委托

6 最后就是实现委托方法,目的就是知道您点击那一个index

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