How to Open a WebView when I press the button in the alert view ?

here is how I define alert view button response

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    if ([alertView tag]==0) {
        if (buttonIndex == 1)
        {   
           //Open WebView with URL string1 
        }
        if (buttonIndex == 2) {
           //Open WebView with URL string2
        }
    }
}

Answer 1

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];
        }
    }
}
