title: IOS keyboard changed its animation
body: <p>I have an ios app, and it's responsive to keyboard appearance.</p>
  
  <p>Before, the keyboard used to slide in from the bottom up</p>
  
  <p>now it appears from the left corner of the top of the keyboard frame down</p>
  
  <p>What happened to create this change? I cannot find any methods that control how the keyboard becomes visible on the screen</p>
