title: No visible @interface for 'GVRVideoView'
body: <p>Ok so I'm trying to implement the Google VR View into my iOS App but am getting this error with the sample project they provide. Anyone experience/overcome this? I double checked that the video it is targeting is present - don't know why it would be that anyway...</p>
  
  <pre><code>  // Load the sample 360 video, which is of type stereo-over-under.
    NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"congo" ofType:@"mp4"];
    [_videoView loadFromUrl:[[NSURL alloc] initFileURLWithPath:videoPath]
                     ofType:kGVRVideoTypeStereoOverUnder];
  }
  </code></pre>
  
  <p>The specific error is:
  <code>No visible @interface for 'GVRVideoView' delcares the selector 'loadFromUrl:ofType:'</code>
  Thanks</p>
