I am loading an External web page in the UIWebView. When the web page loads, there is an Alert Box ( with OK and Cancel buttons) with some Suggestion/ Info about the web page. I want to block this Alert Box when the web page loads in the UIWebView component in my iphone app. How can I implement in my code?

感谢您的答复.我不负责外部网页(但是我可以请关注的网页所有者针对以下要求进行更改).要求是，当我们在iPhone Safari浏览器中查看网页时，可以显示警报框(用于告知我的iphone应用程序)，而在我使用iphone应用程序的UIWebView中不能查看该警告框.我在iPhone Safari和带有UIWebView的iPhone应用程序中都使用了相同的网页URL.因此，要求是当我们在iPHone Safari中查看网页时显示警报"框，而当我们在iPhone应用程序中(在UIWebView中)查看同一网页时不显示警报"框.希望我已经清楚地解释了我的要求.请为此提供任何解决方案.

Thanks for your reply. I am not in-charge for the external web page(but i could ask the concern web page owner to do the changes with respect to following requirement). The requirement is that the Alert Box (used to tell about my iphone app) could be shown when we view the web page in iPhone Safari browswer , but not in UIWebView in which I am using the same web page) of my iphone app. I am using the same web page url both in iPhone Safari and in my iPhone app with UIWebView. So requirement is show the Alert box when we view the web page in iPHone Safari and don't show the Alert box when we view the same web page in iPhone app (within in UIWebView). Hope I have clearly explained my requirement. Please give any solution for this.
