iOS 允许从其他音乐应用程序返回后播放音频

Question

我正在开发音乐应用程序。

这是我想要修复的情况: 我打开 AppleMusic 应用程序 > 播放某些内容 > 打开我的应用程序 > 单击播放 > 音乐不播放。为什么以及如何解决它？

我用了，但还是不行

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(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)
    } catch let error as NSError {
        print(error.localizedDescription)
    }
    UIApplication.shared.beginReceivingRemoteControlEvents()
}

Answer 1

此代码会显示其他应用程序是否正在后台播放声音

var otherAudioPlaying = AVAudioSession.sharedInstance().isOtherAudioPlaying

如果是这样，请尝试以下操作:

AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient, error: nil)
