How do I place a label over an AVPlayer playing a video? - ios

Question

How do I place a label over or "on top of" an AVPlayer playing a video? I have tried adjusting Z-position as suggested in another SO post but it is not working, the video player seems to be in the front of all the labels.
//this is my label
self.commentLabel.layer.masksToBounds = YES;
self.commentLabel.layer.cornerRadius = 15.0;
[self.commentLabel sizeToFit];
self.commentLabel.center = CGPointMake(self.view.frame.size.width/2,self.view.frame.size.height/1.4);
self.commentLabel.layer.zPosition=100;
//this is my video player
self.playerViewController = [[AVPlayerViewController alloc] init];
NSString*str3=[self.FRIENDDATA stringByReplacingOccurrencesOfString:#" " withString:#"_"];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"http://my.website.com/%#/%#.mp4", str3,self.RANDOMDATA]];
AVURLAsset *asset = [AVURLAsset assetWithURL: url];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset: asset];
AVPlayer * player = [[AVPlayer alloc] initWithPlayerItem: item];
self.playerViewController.player = player;
[self.playerViewController.view setFrame:self.referenceImageView.frame];
self.playerViewController.view.layer.zPosition=0;
self.playerViewController.showsPlaybackControls = YES;
[self.view addSubview:self.playerViewController.view];

Answer 1

Have you tried adding the label subview onto the playerViewController ?
[self.playerViewController.view addSubview:self.commentLabel];
From the code I am unsure if commentLabel is not yet initialized or if it initialized somewhere else in the code or from a storyboard. It would be great to initialize the commentLabel on the playerViewController
Like this:
UILabel *commentLabel = [[UILabel alloc]initWithFrame:CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/1.4, 100, 100)];
[self.playerViewController.view addSubview:commentLabel];
That should resolve your issue
