在我的应用程序中单击按钮时打开电话设置 [英] Open phone settings when button is clicked in my app

问题描述

我最近升级到Xcode 8，并将代码转换为Swift3.我正在制作一个自定义键盘(扩展名)，该键盘在iOS 9之前都可以正常工作，但是在iOS 10中我遇到了两个问题.

I recently upgraded to Xcode 8 and converted my code to Swift 3. I am making a custom keyboard (extension) which worked perfectly fine till iOS 9, but i am facing a couple of issues in iOS 10.

1. 自定义键盘的容器应用程序包含一个按钮，该按钮将用户定向到键盘设置以添加键盘

问题:此按钮的点击在iOS 10中不起作用，即用户无权进入设置.我已经在项目中配置了URL方案，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)
    }
}

也尝试过:

@IBAction func btnGetStarted(_ sender: AnyObject) {

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

1. 自定义键盘还包含表情符号图像.用户需要启用设置中的允许访问"才能使用表情符号图像.如果用户未启用允许访问"，则他将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，提示用户进行设置并启用允许访问".

问题:在iOS 10中运行该应用程序时不会弹出此吐司

烤面包的代码:

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)
    }
}

我确实检查了一些关于stackoverflow的解决方案，但是没有一个对我有用，正如我之前说过的那样，我的应用程序在除iOS 10以外的所有版本上都可以正常使用.有人可以帮我吗?

I did check out few solutions on stackoverflow but none of them worked for me, as I said before my app works perfectly fine on all versions except iOS 10. Please can someone help me out?

推荐答案

Swift 3 iOS 10

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