title: IQKeyboardManager not working properly in my view controller
body: <p>Currently I have an UI designed that consists of two simple text fields for resetting password. In my viewm, I haven't used the <code>UIScrollView</code>. So when the UI displays on an iPhone SE, the UI should move up as the <code>UITextField</code> gets hidden behind the keyboard.
  To avoid this, I am using a famous library:</p>

  <p>But still when my UI comes it is not moving up.</p>
