Question

我正在工作的应用程序引导用户完成一次采访，并根据他们的答案发布带有产品推荐的PDF。我目前遇到一些问题，有些手机没有在不可预测的时间正确设置变量。

数据存储在名为“newTracker”的类实例中，并且（对于此问题的范围）答案存储为bool。示例代码来自只有一个问题的屏幕，一个UISwitch和一个“下一步”按钮。

class viewWireVolume: UIViewController {

    // MARK: Properties

    // MARK: Outlets

    @IBOutlet weak var outWireVolume: UISwitch!

    // MARK: Init

    func UIInit(_ animated: Bool) {

        outWireVolume.setOn(newTracker.customerMoreThanOneWire, animated: animated)

    }

    override func viewWillAppear(_ animated: Bool) {

        super.viewWillAppear(animated)
        UIInit(false)

    }

    // MARK: Actions

    @IBAction func actionWireVolume(_ sender: Any) { newTracker.customerMoreThanOneWire = outWireVolume.isOn }

    // MARK: Interface

}

大多数情况下，此代码工作正常，但偶尔也不会保存变量newTracker.customerMoreThanOneWire。当它发生时，它会在整个应用程序中发生，并且代码结构相同。我过去遇到过一个问题，正确地保存了变量，只是没有正确设置初始开关状态，但在这种情况下，它根本不能保存任何东西。

如果将变量设置为Value Change而不是Touch Up Inside会有帮助吗？我很困惑为什么这只会随机发生。当它发生故障时我手里拿着一部手机，后台没有其他应用程序运行，操作系统已更新，似乎没有像越狱或其他任何事情那样的恶作剧。

我无法使用模拟器或连接到我的开发机器的手机复制此内容。

任何见解？

Answer 1

在我最初的问题中，我思索着：＆＃34;如果将变量设置为“价值变化”而非“内部触摸”，它会有所帮助吗？＆＃34;结果证明是整个解决方案。

出于某种原因，将这些UISwitch操作挂钩到TouchUpInside大部分时间都可以工作。由于它在逐步使用较旧的硬件上运行，因此在切换完成更改其值之前，操作似乎会略微触发，因此将不正确的值写入变量。

我将所有内容都转换为价值变化，从那时起我的测试版组就完美无缺。

没有间歇性地设置变量
