title: Force focus ReactNative TextInput
body: <p>I'm having trouble force focussing a react native TextInput field.
  It's focused when the page loads with <code>autofocus={true}</code>.</p>
  
  <p>But after blurring I would need to press the text input field, but that's hidden because of design reasons. Is there a way to <code>document.getElementById("myText").focus();</code> in react native that I can call after <code>onBlur()</code>? </p>
  
  <p>Cheers.</p>
