Siri会 "暂停 "但不会 "播放 "AVPlayer。

Question

我正在做一个iOS电台应用。我希望能够使用Siri来暂停和播放，一旦它已经在播放（Siri不需要启动应用程序，只是控制音频，一旦它已经启动）。现在，"暂停 "在iOS系统中可以从我的手机（但不是从我的手表），但我不能让它 "播放"，一旦它被暂停，即使我仍然在我的锁屏中看到播放器。点击时，锁屏控制功能可以正常工作。

以下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
            }
        }
    }
}

谢谢你，我在做一个iOS广播应用程序

我注意到你实现了 playpause 在指挥中心，但不 play 或 pause. 你可能需要这三样东西。
