swift - 在不使用麦克风的情况下请求麦克风访问 - swift

Question

我的应用程序上的动画 (mp4) 有问题。有时(并非总是)当应用程序启动时，它会请求访问麦克风，但我并没有在应用程序的任何地方请求访问麦克风。我只使用 AVPlayer 来播放 mp4 内容。下面的代码是唯一与播放器相关的代码。知道为什么我被要求访问麦克风吗？谢谢

import UIKit
import Foundation
import MediaPlayer
import AVKit

class AnimationLaunchscreen: UIViewController {

    var player: AVPlayer?

    override func viewDidLoad() {
        super.viewDidLoad()

        let timer = Timer.scheduledTimer(timeInterval: 6.0, target: self, selector: #selector(timeToMoveOn), userInfo: nil, repeats: false)

        self.loadVideo()

    }

    @objc func timeToMoveOn() {
        self.performSegue(withIdentifier: "goToTableView", sender: self)
    }

    func loadVideo() {

        let path = Bundle.main.path(forResource: "stopwatchAnimation", ofType:"mp4")

        let filePathURL = NSURL.fileURL(withPath: path!)
        let player = AVPlayer(url: filePathURL)
        let playerLayer = AVPlayerLayer(player: player)

        playerLayer.frame = self.view.frame
        playerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
        playerLayer.zPosition = -1

        self.view.layer.addSublayer(playerLayer)

        player.seek(to: CMTime.zero)
        player.play()
    }

    override func viewWillAppear(_ animated: Bool) {
        makeStatusBarBlack()
    }

}

在此处添加答案，这样比阅读评论更容易找到。这似乎只是模拟器上的错误(https://forums.developer.apple.com/thread/110423)。在设备上运行效果很好。
