Question

我正在模拟器上运行我的切丁机摇应用程序。它确实通过摇动手势来触发motionEnded。但是，在带有最新iOS版本的真实iPhone 6上运行我的示例源代码，这没有帮助。我带来了this answer的一些内容，但是由于我不了解Objective-C语法，所以无法完全将所有行转换为swift。

以下是我的一些代码：

AppDelegate.swift

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

}

ViewController.swift

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()
    }

}

Answer 1

代码没有错！我确实几乎不需要摇晃手机几次即可触发using (var session = OpenSession()) { }。

迅速：motionEnded不触发或真实设备
