title: Is it mandatory to dismiss a view when it is presented in ios?
body: <p>I am working on iPad App.</p>
  
  <p>Here I am having different views with different orientations. Among them I am PRESENTING a view on clicking button.</p>
  
  <p>While I am DISMISSING that view i am facing orientation problem.</p>
  
  <p>So, to clear that issue i changed the rootviewcontroller after pressing done button where it was dismissed previously.</p>
  
  <p>By doing this my issue was cleared and now not facing any orientation issue.</p>
  
  <p>But what my doubt is does it reaches Apple standards? </p>
  
  <p>Should we dismiss the view if it was presented? Or</p>
  
  <p>should I load the view with any animation effect? Good suggestions appreciated.</p>
