note:I can pop up my Webview , but How to init a URL address to the webview I wanna call ?

Answer 1

web = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];

NSString *urlAddress = [[videolistArray objectAtIndex:indexPath.row] valueForKey:@"video"] ;


NSURL *url = [NSURL URLWithString:urlAddress];


NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[web loadRequest:requestObj];
[self.view addSubview:web];

Answer 2

UIWebView *webView=[[UIWebView alloc] initWithFrame:CGRectMake(0,0,320,480);
[self.view addSubView:webView];




 -(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    if ([alertView tag]==0) {

        NSURLRequest *urlRequest;
        NSURL *urlforWebView;

        if (buttonIndex == 1)
        {   
           urlforWebView=[NSURL URLWithString:@"http://www.google.com"];
           urlRequest=[NSURLRequest requestWithURL:urlforWebView];
           [webView loadRequest:urlRequest];
        }
        if (buttonIndex == 2) 
        {
           urlforWebView=[NSURL URLWithString:@"http://www.yahoo.com"];
           urlRequest=[NSURLRequest requestWithURL:urlforWebView];
           [webView loadRequest:urlRequest];
        }
    }
}
