Following a html link from an iphone app

I have a couple of html links attached to buttons in my app. I'm just wondering whats the best practice for following a html link in an iphone app.

I'm not sure if the 开发者_Go百科app should exit and open safari or if a web container should be used etc.

There's no real best practice, it's whatever you think your users would appreciate. Some apps offer the best of both worlds, by putting a UIWebView in their app to view web content and then a button to open the same page in Safari.
