ios - swift:motionEnded 不触发或真实设备

Question

我正在模拟器上运行我的 dicer shake 应用程序。它确实通过摇动手势触发 motionEnded。然而，在具有最新 iOS 版本的真实 iPhone 6 上运行我的示例源代码，它没有帮助。我从 this answer 带来了一些零件，但由于我不知道 Objective-C 语法，我无法将所有行完全转换为 swift。

这是我的一些代码:

AppDelegate.swift

func applicationDidFinishLaunching(_ application: UIApplication) {
    application.applicationSupportsShakeToEdit = true

}

import UIKit

class ViewController: UIViewController {
    var randomDiceIndex1:Int = 0
    var randomDiceIndex2:Int = 0
    let diceArray = ["dice1","dice2","dice3","dice4","dice5","dice6"]

    @IBOutlet weak var diceImageView1: UIImageView!
    @IBOutlet weak var diceImageView2: UIImageView!



    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        updateDiceImages()
    }
    @IBAction func rollButtonPressed(_ sender: UIButton) {
         // A Block of Code
        updateDiceImages()

    }
    func updateDiceImages(){
        randomDiceIndex1 = Int.random(in: 0 ... 5)
        randomDiceIndex2 = Int.random(in: 0 ... 5)
        print(randomDiceIndex1)
        diceImageView1.image = UIImage(named: diceArray[randomDiceIndex1])
        diceImageView2.image = UIImage(named: diceArray[randomDiceIndex2])

    }
    override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
            updateDiceImages()
    }

    override var canBecomeFirstResponder: Bool{
        return true
    }
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        becomeFirstResponder()
    }

}

代码没有任何问题!我确实需要摇晃手机几次才能触发 motionEnded。
