Control UIWebView from the web page

Question

How can I control the UIWebView in an iOS app from the web page?

For example, I want to resize it - not by setting the UIWebView's frame (in the Objective C code), but with some Javascript code, like window.resizeTo()

I've heard that I should implement a class that enables external control on the UIWebView. Does anyone know which class is it?

Thanks, Keren

Answer 1

Check out lines 26-45 in this class.

Is that what you are looking for?

I was using a UIWebView within a chat app. You can basically make a UIWebView do any JavaScript you want.

Two things you can look at:

• the UIWebView method stringByEvaluatingJavaScriptFromString

• the UIWebView Delegate Protocol Reference, especially the webView:shouldStartLoadWithRequest method
