How to add a link to a website with a button and get back to the app

I was wondering how to add a link to a website so that when the user taps on a button, he will be taken to that webpage, but can then hit an 开发者_JS百科x in the top left corner or hit the home button and then it will take them back to their app. I want it to be like iad where it doesn't close your app when you click on that link.

You can implement your own UIWebView in your app which will display the link, and handle all of the navigation. There are many tutorials on the web. Hope that Helps!
