无法识别的选择器已发送到实例（'NSInvalidArgumentException'）

Question

I'm setting up a class to view video using Google VR. It runs without error using the sample code. When I copy the class and view controller over to my project, this error occurs:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setDelegate:]: unrecognized selector sent to instance 0x109d04d90'

Here's the relevant code:

  @interface VideoPlayerViewController () <GVRVideoViewDelegate>
  @property(nonatomic) IBOutlet GVRVideoView *videoView;
  @property(nonatomic) IBOutlet UITextView *attributionTextView;
  @end

  _videoView.delegate = self;
  _videoView.enableFullscreenButton = YES;
  _videoView.enableCardboardButton = YES;
  _videoView.enableTouchTracking = YES;

I can't figure out why it works in one instance and not the other. Everything is connected up in the storyboard.

This is driving me crazy. Please help!

Try like this

Open storyboard in Scrollview choose the video view and then Choose the Custom class.Then give the class name as GVRVideoView.
