AVPlayer video still playing after segue to next view controller - ios

Question

I'm currently looping my mp4 video with no playback controls, kind of like a gif but with sound. But I do not know why when I segue to the next view controller, the video is still playing. Does anybody know the simplest method to resolve this issue?
ViewController
import UIKit
import AVKit
import AVFoundation
fileprivate var playerObserver: Any?
class ScoreController: UIViewController {
#IBOutlet var label: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let returnValue: Int = UserDefaults.standard.integer(forKey: "userScore")
label.text = "Your Score: \(returnValue)/30"
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
let path = Bundle.main.path(forResource: "Innie-Kiss", ofType:"mp4")
let player = AVPlayer(url: URL(fileURLWithPath: path!))
let resetPlayer = {
player.seek(to: kCMTimeZero)
player.play()
}
playerObserver = NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem, queue: nil) { notification in resetPlayer() }
let controller = AVPlayerViewController()
controller.player = player
controller.showsPlaybackControls = false
self.addChildViewController(controller)
let screenSize = UIScreen.main.bounds.size
let videoFrame = CGRect(x: 0, y: 130, width: screenSize.width, height: (screenSize.height - 130) / 2)
controller.view.frame = videoFrame
self.view.addSubview(controller.view)
player.play()
} catch {
}
}
override func viewDidDisappear(_ animated: Bool) {
super.viewDidDisappear(animated)
}
fileprivate var player: AVPlayer? {
didSet { player?.play() }
}
deinit {
guard let observer = playerObserver else { return }
NotificationCenter.default.removeObserver(observer)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func doneButton(_ sender: Any) {
self.performSegue(withIdentifier: "done", sender: self)
}
}

Answer 1

In viewWillDisapper() or button action for segue do this :
NotificationCenter.default.removeObserver(self)
Also move this from viewDidLoad() to some function like :
var player: AVPlayer?
func audioPlayer(){
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
let path = Bundle.main.path(forResource: "Innie-Kiss", ofType:"mp4")
player = AVPlayer(url: URL(fileURLWithPath: path!))
let resetPlayer = {
self.player?.seek(to: kCMTimeZero)
self.player?.play()
}
playerObserver = NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player?.currentItem, queue: nil) { notification in resetPlayer() }
let controller = AVPlayerViewController()
controller.player = player
controller.showsPlaybackControls = false
self.addChildViewController(controller)
let screenSize = UIScreen.main.bounds.size
let videoFrame = CGRect(x: 0, y: 130, width: screenSize.width, height: (screenSize.height - 130) / 2)
controller.view.frame = videoFrame
self.view.addSubview(controller.view)
player?.play()
} catch {
}
}
and make player object a global variable. var player = AVPlayer? and in viewWillDisappear make it nil.
So your viewWillDisappear should look like this :
override func viewWillDisappear(_ animated: Bool) {
NotificationCenter.default.removeObserver(self)
if player != nil{
player?.replaceCurrentItem(with: nil)
player = nil
}
}

Answer 2

override func viewWillDisappear(_ animated: Bool) {
}
This may be helpful to you if you are switching windows; as you perform a segue, you will execute the function included in curly brackets automatically. I'm rubbish with AV, but some of the other's code suggested to turn off the function may work here if it isn't working in the IBAction.
I'm not great with Xcode though, so mileage will probably vary.

I had this issue and fixed it by adding this line before setting player to nil:
[self.player pause];
here is my viewWillDisapear:
- (void)viewWillDisappear:(BOOL)animated
{
[[NSNotificationCenter defaultCenter] removeObserver:self
name:AVPlayerItemDidPlayToEndTimeNotification
object:self.player];
[self.player removeObserver:self forKeyPath:#"rate"];
[self.player removeTimeObserver:self.playerObserver];
self.playerObserver = nil;
[self.player pause];
self.player = nil;
[[UIDevice currentDevice] setValue:#(UIInterfaceOrientationPortrait) forKey:#"orientation"];
[UINavigationController attemptRotationToDeviceOrientation];
[StayfilmApp restrictOrientation:YES];
}

class ScoreController: UIViewController {
#IBOutlet var label: UILabel!
var player: AVPlayer?
override func viewDidLoad() {
super.viewDidLoad()
let returnValue: Int = UserDefaults.standard.integer(forKey: "userScore")
label.text = "Your Score: \(returnValue)/30"
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
let path = Bundle.main.path(forResource: "Innie-Kiss", ofType:"mp4")
player = AVPlayer(url: URL(fileURLWithPath: path!))
let resetPlayer = {
player.seek(to: kCMTimeZero)
player.play()
}
playerObserver = NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem, queue: nil) { notification in resetPlayer() }
let controller = AVPlayerViewController()
controller.player = player
controller.showsPlaybackControls = false
self.addChildViewController(controller)
let screenSize = UIScreen.main.bounds.size
let videoFrame = CGRect(x: 0, y: 130, width: screenSize.width, height: (screenSize.height - 130) / 2)
controller.view.frame = videoFrame
self.view.addSubview(controller.view)
player.play()
} catch {
}
}
override func viewDidDisappear(_ animated: Bool) {
super.viewDidDisappear(animated)
player.pause()
}
fileprivate var player: AVPlayer? {
didSet { player?.play() }
}
deinit {
guard let observer = playerObserver else { return }
NotificationCenter.default.removeObserver(observer)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func doneButton(_ sender: Any) {
self.performSegue(withIdentifier: "done", sender: self)
}
}
notable changes:
var player: AVPlayer?
and also
override func viewDidDisappear(_ animated: Bool) {
super.viewDidDisappear(animated)
NotificationCenter.default.removeObserver(self)
player?.pause()
}

I have the same problem when I used segue to go to the next ViewController, then I used present code with swift by using this code
#IBAction func next(_ sender: Any) {
let vc = self .storyboard?.instantiateViewController(withIdentifier:"ViewControllerAA") as! ViewControllerAA
self.present(vc,animated: true,completion: nil)
}
but the problem didn't solve , then I used this code to go to the next VC and my problem solved and the background sound of the video stoped, and the code is this below
#IBAction func next(_ sender: Any) {
if let vc = self.storyboard?.instantiateViewController(withIdentifier: "ViewControllerAA") as? ViewControllerAA {
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.window?.rootViewController = vc
}
}
