title: How to remove focus from a ion-input in Angular 2+/Ionic2+
body: <p>It is possible to set focus using setFocus method from nativeEloment.</p>
  
  <p>But how about remove focus?</p>
  
  <p>How could I remove the cursor from and unselect an input from a template in a Angular 2+/Ionic 3 app?</p>
  
  <p>I need to remove the focus because the mobile keyboard keeps open while a input has focus.</p>
  
  <p><strong>Edit: The input is a ion-input of Ionic2+.</strong></p>
