I try to parse a HTML page that use java script to create some content, I found stringWithContentsOfURL can't give me right result, because there is no contents created by java script, what can I do?

Embed a UIWebView (not necessarily visible), load the page, let the JS run and then interact

Can it be run in background like Safari?

If you mean whilst your app is suspended I suspect no. If you mean whilst your app is the active app then yes, it would load happily.

But it is said UI only can be run in Main thread...

1) I said nothing about threads: you have decided to add this
2) An offscreen (or simply z-layered behind the other views) view implies nothing about threads
