在我的应用程序中单击按钮时打开手机设置

Question

我最近升级到Xcode 8并将我的代码转换为Swift 3.我正在制作一个自定义键盘(扩展),它完美地运行到iOS 9,但我在iOS 10中遇到了一些问题.

1. 自定义键盘的容器应用程序包含一个按钮,用于将用户引导至键盘设置以添加键盘

问题:此按钮单击在iOS 10中不起作用,即用户未定向到设置.我在项目中配置了URL Schemes并尝试了以下代码:

@IBAction func btnGetStarted(_ sender: AnyObject) {

    let settingsUrl = URL(string: UIApplicationOpenSettingsURLString)
    if let url = settingsUrl {
        UIApplication.shared.openURL(url)
    }
}

还尝试过:

@IBAction func btnGetStarted(_ sender: AnyObject) {

if let settingsURL = URL(string:"prefs:root=General&path=Keyboard/KEYBOARDS") {
 UIApplication.shared.openURL(settingsURL)
 }
}

2. 自定义键盘还包含表情符号图像.用户需要在设置中启用"允许访问"才能使用表情符号图像.如果用户未启用"允许访问",则他无法使用表情符号图像.如果未启用"允许访问"并且用户尝试单击表情符号,则会弹出一个吐司,告诉用户转到设置并启用"允许访问".

问题:当应用程序在iOS 10中运行时,不会弹出此Toast

吐司代码:

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath){

    let pbWrapped: UIPasteboard? = UIPasteboard.general

    if let pb = pbWrapped {
        if  currentKeyboard == XXXXXX.emoji {
            if let data = UIImagePNGRepresentation(dataEmoji[(indexPath as NSIndexPath).row]) {
                pb.setData(data, forPasteboardType: "public.png")

                  self.makeToast(pasteMessage, duration: 3.0, position: .center)
            }
        }

    } else {
        var style = ToastStyle()
        style.messageColor = UIColor.red
        style.messageAlignment = .center
        //style.backgroundColor = UIColor.whiteColor()

        self.makeToast("To really enjoy the keyboard, please Allow Full Access in the settings application.", duration: 8.0, position: .center, title: nil, image: UIImage(named: "toast.png"), style: style, completion: nil)
    }
}

我确实在stackoverflow上查看了一些解决方案,但它们都没有为我工作,正如我之前所说的那样,除了iOS 10之外的所有版本都可以正常工作.请有人帮帮我吗？

Swift 3 iOS 10

let settingsUrl = NSURL(string:UIApplicationOpenSettingsURLString) as! URL
UIApplication.shared.open(settingsUrl, options: [:], completionHandler: nil)
