Swift 3.0 AVAudioPlayer 通过音乐播放音频 [英] Swift 3.0 AVAudioPlayer Playing audio over music

问题描述

目前这是我用来在按下按钮时播放声音的代码.

Currently this is the code I'm using to play my sound during the button press.

var player: AVAudioPlayer?

    let url = Bundle.main.url(forResource: "Sound/yatch", withExtension: "mp3")!

    do {
        player = try AVAudioPlayer(contentsOf: url)
        guard let player = player else { return }

        player.prepareToPlay()
        player.play()
    } catch let error {
        print(error.localizedDescription)
    }

我试图让这个音频在当前播放的内容上运行(例如 Spotify、pandora、音乐).我该怎么做?

Im trying to get this audio to run over whats currently playing (etc Spotify, pandora, Music). How would I go about doing this?

推荐答案

设置应用程序的音频会话以在当前播放的音频上播放:

Set the audio session of your application to play over the currently playing audio:

try? AVAudioSession.sharedInstance().setActive(true)
try? AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)

根据 AVAudioSession 标头，AVAudioSessionCategoryAmbient 将播放音频和音乐等

According to the AVAudioSession headers, AVAudioSessionCategoryAmbient will play audio with music, etc.

/*  Use this category for background sounds such as rain, car engine noise, etc.
 Mixes with other music. */
public let AVAudioSessionCategoryAmbient: String
