Wish I could have made it, but had to take care of the kids first. If there is a person willing to give expert UIWebView advice via email, please contact me.

  What's your UIWebView question?

  How to accurately enable the back button for a UIWebView. The delegates don't get called when a JS/AJAX event changes the page. The back button works in these instances if it is enabled. But there is no straight forward way to enable the button at the correct time.

  So the UIWebView doesn't have a back button but does have the canGoBack method - are you saying that that method is not returning the right value? Also, I don't know of a delegate method that will alert you when JS/AJAX does anything because basically there is no way to know that - JS could be doing all sorts of things behind the scenes to the UIWebView content. If canGoBack is the correct value then you can use a timer to check it a few times a second and manage your button accordingly.

  If that does NOT work then you can always trigger a custom scheme url (after your AJAX call returns for instance) from the JS code that will then trigger the delegate via the webView:shouldStartLoadWithRequest:navigationType: method. You can then return NO so it doesn't actually do anything but your app can then get a chance to enable/disable your button accordingly. This sample shows communication between UIWebView and iOS code that shows this type of technique. https://github.com/zob...
