> It's possible from tests I did with my proof of concept based on this header: 
> http://opensource.apple.com/source/WebKit/WebKit-6531.9/mac/WebView/WebScriptDebugDelegate.h
> You would then set the delegate on a UIWebView subclass that overrode this 
> selector:
> {code}
> - (void)webView:(id)sender didClearWindowObject:(id)windowObject 
> forFrame:(WebFrame*)frame
> {
>     [sender setScriptDebugDelegate:myWebScriptDebugDelegate]; // e.g
> }
> {code}
> webView:didClearWindowObject:forFrame: 
> https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/WebKit/Protocols/WebFrameLoadDelegate_Protocol/Reference/Reference.html
> Of course this will involve private methods (not kosher by Apple), and might 
> not be baked in (but included in the source that is installed), and we could 
> provide instructions on how to explicitly include and enable it and output 
> warnings if it is used.
