Changing code using MPMoviePlayerController to AVPlayer - ios

Question

I'm taking an online course and they're using outdated code using MPMoviePlayerController, and I need specific instructions on what to change it to so that it works. The app I'm making has a table view controller with an inbox with messages in it. Short video files can be sent, and when you tap on a row that has a video message, I need the video file to play. The free trial is expiring soon, so I need help please.
This is what needs to be changed in my header file:
#property (nonatomic, strong) MPMoviePlayerController *moviePlayer;
This is what needs to be changed in my viewDidLoad method in my implementation file:
self.moviePlayer = [[MPMoviePlayerController alloc] init];
This is also what needs to be changed in the implementation file. I'm getting the videos through a backend via Parse.com, so that's what the PFFile is about:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
PFFile *videoFile = [self.selectedMessage objectForKey:#"file"];
NSURL *fileUrl = [NSURL URLWithString:videoFile.url];
self.moviePlayer.contentURL = fileUrl;
[self.moviePlayer prepareToPlay];
[self.view addSubview:self.moviePlayer.view];
[self.moviePlayer setFullscreen:YES animated:YES];
}

In header file :
#property(nonatomic,strong)AVPlayer *avPlayer;
In viewDidLoad method in implementation file
self.avPlayer = [[AVPlayer alloc] init];
In implementation UITableView Method :
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
PFFile *videoFile = [self.selectedMessage objectForKey:#"file"];
NSURL *fileURL = [NSURL fileURLWithPath:videoFile.url];
self.avPlayer = [AVPlayer playerWithURL:fileURL];
AVPlayerLayer *layer = [AVPlayerLayer playerLayerWithPlayer:self.avPlayer];
self.avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;
layer.frame = CGRectMake(0, 0, width, height);
[self.view.layer addSublayer: layer];
[self.avPlayer play];
}
Hope it will help you :)
