iMessage style within the app?

Hey everyone,

First of all, big shout out to Ben. Your lessons have been awesome so far and I am really enjoying them! I have learned a lot in just a few hours.

Second, I am trying to implement a private message kind of system, think: facebook messenger, twitter DMs, and even messages on Tinder. I want to implement this within my app and i was wondering if anyone knew of an easy way to do so? Especially using Parse. Is there a tutorial/api or something out there I could implement?

It seems tinder and facebook messenger both use something pretty much identical to iMessage in iOS7. I am wondering if there is something out there I am missing or these guys are actually just good at it. Tinder even has the "select and drag to the left to see the time it was sent" feature. That's a long name for a feature, I am going to copyright it.

Thanks in advance for any help you may provide!
