Put this line before calling play()method of AVPlayer.

将此行放在调用AVPlayer 的play()方法之前。

In Objective C

在目标 C

[[AVAudioSession sharedInstance]
            setCategory: AVAudioSessionCategoryPlayback
                  error: nil];

In Swift

在斯威夫特

do {
    try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
 }
 catch {
    // report for an error
 }

Swift 5

do {
      try AVAudioSession.sharedInstance().setCategory(.playback)
   } catch(let error) {
       print(error.localizedDescription)
   }

Play sound in Video when device is on RINGER mode and SLIENT mode

当设备处于 RINGER 模式和 SLIENT 模式时在视频中播放声音

 do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        //print("AVAudioSession Category Playback OK")
        do {
            try AVAudioSession.sharedInstance().setActive(true)

You can use AppDelegateclass.

你可以使用AppDelegate类。

For enable sound (for audio or video) when device is in silent mode use AVAudioSessionCategoryPlayback:

要在设备处于静音模式时启用声音（音频或视频），请使用AVAudioSessionCategoryPlayback：

func applicationDidBecomeActive(_ application: UIApplication) {

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    } catch {
        print("AVAudioSessionCategoryPlayback not work")
    }
}

For disable sound when device is in silent mode (for example when we answer the phone call) use AVAudioSessionCategorySoloAmbient:

要在设备处于静音模式时（例如，当我们接听电话时）禁用声音，请使用AVAudioSessionCategorySoloAmbient：

func applicationWillResignActive(_ application: UIApplication) {

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategorySoloAmbient)
    } catch {
        print("AVAudioSessionCategorySoloAmbient not work")
    }
}

import AVKit

And add this to your AppDelegate's applicationDidBecomeActivesection

并将其添加到您的 AppDelegateapplicationDidBecomeActive部分

func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
            print("AVAudioSession Category Playback OK")
            do {
                try AVAudioSession.sharedInstance().setActive(true)
                print("AVAudioSession is Active")
            } catch {
                print(error.localizedDescription)
            }
        } catch {
            print(error.localizedDescription)
        }
    }

You can go through this, it will help you out

你可以通过这个，它会帮助你

When you use following audio session categories, sounds will not be muted on iOS: AVAudioSessionCategoryPlayback,AVAudioSessionCategoryRecord,AVAudioSessionCategoryPlayAndRecord

当您使用以下音频会话类别时，iOS 上的声音将不会被静音： AVAudioSessionCategoryPlayback,AVAudioSessionCategoryRecord,AVAudioSessionCategoryPlayAndRecord

Example

例子

func playSound (Sound: String, Type: String) {

        //Prepare the sound file name & extension
        var alertSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(Sound, ofType: Type)!)

        //Preparation to play
        AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: nil)
        AVAudioSession.sharedInstance().setActive(true, error: nil)

        //Play audio

        var error: NSError?
        audioPlayer = AVAudioPlayer(contentsOfURL: alertSound, error: &error)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
        }
