title: Ionic: first time input field focus keyboards hides right after coming up only on IOS
body: <p>Hello fellow programmers,</p>
  
  <p>I've been working on an app for a while now and I've been experiencing a problem with the keyboard. When I tab on an input field for the first time the keyboard shows up, but hides afterwards. This happens in a short time. When I tab the input field the second time it works normally.</p>
  
  <p>I have no clue what the problem could be. I've installed the ionic-keyboard plugin and I thought the problem could be related with that plugin. So I've uninstalled it and re-installed it, but my problem wasn't solved.</p>
  
  <p>Any of you had a similar problem?</p>
  
  <p>If so, please let me know!</p>
  
  <p>I would be grateful if someone could give me the solution or at least point me into the right direction.</p>
  
  <p>Thanks.</p>
