Chris Brody commented on CB-535:
--------------------------------

Is it possible to put something in the AppDelegate.h (or .m) in the generated code?

> 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.
