Siri 会 "pause" 但不会 "play" AVPlayer

Question

我正在制作一个 iOS 广播应用程序。我希望能够在播放时使用 Siri 暂停和播放（Siri 不需要启动应用程序，只需在启动后控制音频）。现在 "pause" 在 iOS 从我的 phone 工作（但不是从我的手表），但一旦暂停，我就无法将它转到 "play"，即使我仍然在我的锁定屏幕中看到播放器。点击时锁定屏幕控件工作正常。

下面是一些可能相关的代码：

func setupRemoteCommandCenter() {
    let commandCenter = MPRemoteCommandCenter.shared()


    // MARK: PLAY/PAUSE
    commandCenter.togglePlayPauseCommand.addTarget { event in
        self.togglePlayPause()
        return .success
    }


    // MARK: Skip
    func skipBackward(_ event: MPRemoteCommandEvent) -> MPRemoteCommandHandlerStatus {
        guard let command = event.command as? MPSkipIntervalCommand else {
            return .noSuchContent
        }

        goBackward15()

        return .success
    }

    let skipBackwardCommand = commandCenter.skipBackwardCommand
    skipBackwardCommand.isEnabled = !playingLivestream
    skipBackwardCommand.addTarget(handler: skipBackward)
    skipBackwardCommand.preferredIntervals = [-15]

    func skipForward(_ event: MPRemoteCommandEvent) -> MPRemoteCommandHandlerStatus {
        guard let command = event.command as? MPSkipIntervalCommand else {
            return .noSuchContent
        }

        goForward30()

        return .success
    }

    let skipForwardCommand = commandCenter.skipForwardCommand
    skipForwardCommand.isEnabled = !playingLivestream
    skipForwardCommand.addTarget(handler: skipForward)
    skipForwardCommand.preferredIntervals = [30]        
}

@objc func handleInterruption(notification: Notification) {
    guard let userInfo = notification.userInfo,
        let typeValue = userInfo[AVAudioSessionInterruptionTypeKey] as? UInt,
        let type = AVAudioSession.InterruptionType(rawValue: typeValue) else {
            return
    }

    if type == .began {
        print("Interruption began")
        // Interruption began, take appropriate actions
    }
    else if type == .ended {
        if let optionsValue = userInfo[AVAudioSessionInterruptionOptionKey] as? UInt {
            let options = AVAudioSession.InterruptionOptions(rawValue: optionsValue)
            if options.contains(.shouldResume) {
                // Interruption Ended - playback should resume
                print("Interruption Ended - playback should resume")
                play()
            } else {
                // Interruption Ended - playback should NOT resume
                print("Interruption Ended - playback should NOT resume")
                playerPaused = true
            }
        }
    }
}

谢谢。

我注意到您在指挥中心实施了 playpause，但没有实施 play 或 pause。您可能需要所有这三个。

Siri 会 "pause" 但不会 "play" AVPlayer

Siri will "pause" but not "play" AVPlayer

swift

avplayer
