play video forever in sprite kit

问题

i am having an issue with playing back a video in my intro scene. i have added my video to the scene and it plays fine. i just want it to repeat again and again. is there any way to set this video to playback automatically after it ends?

this is how i add the video:

SKVideoNode *videoNode = [SKVideoNode videoNodeWithVideoFileNamed:@"game1.m4v"];
videoNode.position = CGPointMake(150, 180);
videoNode.size = CGSizeMake(150, 150);
[self addChild:videoNode];
[videoNode play];

any help is appreciated.

Initialize your SKVideoNode with:

- (instancetype)initWithAVPlayer:(AVPlayer *)player

When setting up the AVPlayer use:

avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone; 

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemDidReachEnd:)
                                             name:AVPlayerItemDidPlayToEndTimeNotification
                                           object:[avPlayer currentItem]];

this will prevent the player to pause at the end.

In the notification:

-(void)playerItemDidReachEnd:(NSNotification *)notification {
    AVPlayerItem *p = [notification object];
    [p seekToTime:kCMTimeZero];
}

this will rewind the movie.
