title: Playback restricted on iOS for VEVO videos from YouTube API
body: <p>I have embedded videos (pulled from YouTube API v3) into my iPhone app using a UIWebView as suggested.  The problem is that some videos, such as those from VEVO, produce the following error when attempting to play them on the device.</p>
  
  <blockquote>
    <p>This video contains content from VEVO.  It is restricted from playback on certain sites.</p>
  </blockquote>
  
  <p>This should not occur, since <strong>apps like Flipboard and Rockpack also seem to be using a UIWebView, and are able to play videos from VEVO and other sources.</strong></p>
  
  <p>What could I be doing wrong?</p>
  
  <p>PS: I am aware that there exist other posts that touch upon this issue in some way, but they fail to address this specific problem.</p>
