I feel like I'm doing this wrong, or it's just a result of my novice with sockets. I'm using asyncSocket on the iPhone to send data to node.js. My problem is that every so often, the app will hang, and then I'll get like 5 or 10 messages at once in one data read, rather than separate, more timely reads. Is this a network hiccup and the ...

I can't see an obvious way to grab a handle to the controller f...

I took the time to set up some Unit Tests and set up the targets in XCode, etc., and they're pretty useful for a few classes. However: I want to test small UI pieces for which I don't want to launch the entire application.
