PORobust real-time communication between iOS App and Mac App

copied!<p>We're working on an exhibit (<a href="http://pulse.media.mit.edu" rel="nofollow">http://pulse.media.mit.edu</a>) and I'm brand new to iOS, objective-c and Xcode. The exhibit deadline is in one week and I'm stuck.</p> <p>The problem I'm having seemed simple enough.</p> <p>Our exhibit has a projector and an iPad. The projector will be hooked up to a mac and be playing a video. The iPad will act as a controller for those videos. More simply:</p> <p>I have 50 videos on a Mac. I need to develop an application on the Mac, that, when opened will loop one of the videos.</p> <p>On an iPad, I need to develop an app that can change between the videos on the mac in real time. The iOS app is already designed, we're just struggling with some code. </p> <p>On the mac, when the iPad tells the Mac to change video, we'd like it to switch between videos using Core Animation, like this (http://youtu.be/pyd8O-2mkgk?t=1m).</p> <p>So my question: What is the most robust way to do this? It has to be able to run in a museum, for two months. Some things to consider: </p> <ul> <li>We are 4,000 miles away and can't monitor it all the time. We'll check nightly to see if it's still working, but it should run the day without breaking. </li> <li>If people unplug the iPad, it should still work.</li> <li>It should be as robust as possible.</li> </ul> <p><strong>How can I best do this? Should I write to a database from the iPad onto a database running locally on the connected Mac and then monitor that database 10 times every second? Are sockets robust enough to use alone?</strong></p> <p>If you do suggest a way, can you please point me in the direction of some resources (frameworks, function names, etc) that can help me do this quickly? </p> <p>Thank you for your time.</p>
