At the very least, I guess I'm hoping for a reference to some really solid documentation on how to do what I'm trying to do - the documentation on ADC seems to be a little light in this area.
>From the code you've posted, I suspect the problem is that the page
hasn't actually loaded by the time you try to run your JS code.
WebView generally works asynchronously. Something like [mainFrame
loadRequest:request] will return quickly and the WebView will not
actually load things until the runloop runs, and then you'll get
notified later on when it's done loading.
What you'll want to do is call loadRequest:, then run the NSRunLoop on
the main thread until your load delegate is told that the page is done
loading. Then you should be able to do your JS stuff.
Note that it is possible, and not all that hard, to run an NSRunLoop
in a faceless program, it just requires a bit more manual intervention
than in a GUI app where it's all set up for you.
If you're already doing that and your code was just abbreviated, well,
ignore the above....
