I\'m trying to achieve similar positioning behavior as the bottom text input bar in Apple\'s Messages app.

There's an excellent, easy-to-implement, open-source solution to this from the good folks at Slack: SlackTextViewController.

Here's how to implement a view with a docked toolbar in four steps:

1. Install the pod into your project. (http://cocoapods.org/?q=SlackTextViewController)
2. If you're writing an app in Swift, create a header to bridge between your Swift code and their Obj-C classes. Here's a nice quick walkthrough on that. (The bridging header won't be necessary once the classes are translated into Swift, anyone want to collaborate on that?)

3. Create a MessageViewController that inherits from SLKTextViewController, no need to write any more code than this:

   import Foundation
   import UIKit
   
   class MessageViewController: SLKTextViewController {
   
       required init(coder aDecoder: NSCoder!) {
           super.init(coder: aDecoder)
       }
   }
   

4. In Storyboard, create a View Controller that inherits from MessageViewController.
5. Test the app on a device or emulator, you'll see a beautiful docked textbar that also (as a bonus) expands as the user writes additional lines of text.

Props to the team at Slack for extracting such a useful pod.
