title: iOS 8 after hiding tab bar - reuse this space to display a text box
body: <p>I can hide the tab bar programmatically. The view underneath is a scrollview displaying content. When I scroll up/down I can see the white space at the bottom where the tab bar used to be. My content is not able to use that space.</p>
  
  <p>I want to display a text box in that white space along with some buttons. Any suggestions on how can I do that?</p>
  
  <p>Solution:
  Thanks to "SwiftArchitect" advice. I was able to fix this by adding bottom constraints for the ScrollView. Now the scrollview goes till the bottom of the screen. </p>
