I have several html links attached to buttons in my application. I'm just wondering what is best for html link in iphone app.
I'm not sure if the app should exit and open safari or use a web container, etc.
There is no real best practice, this is all you think your users will 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.
