What are some methods to debug Javascript inside of a UIWebView?

This query tops google, so worth linking to the remoteInspector hidden in iOS5 - by far the best way found so far to debug your UIWebViews - just conditional compile out before you send to Apple.

If you're using iOS >= 6 and you have mountain lion (10.8) or Safari >= 6, you can just:

1. Open the application in the simulator (or your device in XCode >= 4.5.x).
2. Open Safari (go to Preferences -> Advanced and make sure "Show Develop Menu in Menubar" is on.
3. From the Menu-bar (of Safari) select Develop -> iPhone Simulator -> [your webview page].

That's it !
