Back/Forward buttons for UIWebView - canGoBack not working with ajax sites

Question

I'm using some toolbar buttons for going back and forwards through historic webpages in a UIWebview.

I am enabling/disabling these buttons using [webview canGoBack] called at webViewDidStartLoad. Works fine on most sites, but the problem is, on sites like twitter and facebook who use javascript/ajax requests to reload new pages canGoBack and canGoForward do not recognise a page change so my buttons don't become active.

Is there a way round this?

Answer 1

In my experience, the site itself has to support back/forward on top of their AJAX requests. It would require the web application to change the URL for each page navigation.

See http://www.devx.com/webdev/Article/35549 for some discussion on this issue.

So, specific to your question - if it's your own web app, it's definitely possible (there are several javascript solutions, one of which is linked above), but for 3rd party web apps, I'd say no.
