This is a different question regarding a suitable framework, methodology, template app, tutorial, or just helpful hints, on developing native apps (not just web apps) that are cro...
I have a small bug in my client app that uses NSURLConnection. I have tracked it down to an unexpected connection keep-alive that seems to confuse the web server (probably a bug on the server side).
