Question

我有一个带有文本字段的今日扩展。我想使用文本字段的内容作为URL在我的应用程序中打开浏览器。

这是我的小部件的TodayViewController.swift

import UIKit
import SafariServices
import NotificationCenter

// This extension to remove the white spaces from what pasteed   
extension String {
func replace(string:String, replacement:String) -> String {
    return self.replacingOccurrences(of: string, with: replacement,             
options: NSString.CompareOptions.literal, range: nil)
}

func removeWhitespace() -> String {
    return self.replace(string: " ", replacement: "")
}
}


class TodayViewController: UIViewController, NCWidgetProviding {

var clearNumber: String?

override func viewDidLoad() {
    super.viewDidLoad()

}


func widgetPerformUpdate(completionHandler: (@escaping (NCUpdateResult) -> Void)) {
    // Perform any setup necessary in order to update the view.

    // If an error is encountered, use NCUpdateResult.Failed
    // If there's no update required, use NCUpdateResult.NoData
    // If there's an update, use NCUpdateResult.NewData

    completionHandler(NCUpdateResult.newData)
}



@IBOutlet weak var textBox: UITextField!

@IBAction func clearNumber(_ sender: Any) {

    if textBox.hasText == true {
        textBox.text = ""
    }else{
        return
    }

}

@IBAction func pasteNumber(_ sender: Any) {

    if let myString = UIPasteboard.general.string {
        let pasteNumber = myString.removeWhitespace()
        textBox.insertText(pasteNumber)
    }else{
        return
    }
}

@IBAction func goButton(_ sender: Any) {

    let myAppUrl = URL(string: "main-screen:")!
    extensionContext?.open(myAppUrl, completionHandler: { (success) in
        if (!success) {
            print("error: failed to open app from Today Extension")
        }
    })
}

您可以使用@Giuseppe_Lanza解决方案并解析从Today Extension Widget收到的网址。但是，我会展示一个示例，其中您的网址包含静态组件，并根据用户在textField中的输入查找https:/www.apple.com/homepod或https:/www.apple.com/iphone之类的路径：

1- URL方案：myAppName

2-添加此项以使用小部件打开您的应用

@IBAction func goButton(_ sender: Any) {
    openApp(widgetText: "\(textBox.text!)")
}

func openApp(widgetText:String)    {

    let str = "myAppName://https://www.apple.com/\(widgetText)"
    let url = URL(string: str)!
    if textBox.hasText == true  {

        extensionContext?.open(url, completionHandler: { (success) in
            if (!success) {
                print("error:  ")
            }
        })
    }
}

3- AppDelegate

定义一个变量并将收到的url传递给webViewController，将在那里解析url。

open var receivedUrl:URL?

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool{

    receivedUrl = url
    //You need to alter this navigation to match your app requirement so that you get a reference to your previous view..
    window?.rootViewController?.performSegue(withIdentifier: "toDeepLink", sender: nil)
}

确保在属性下为此segue添加标识符检查员为toDeepLink。

4- WebView＆amp;解析网址现在你可以像这样获得receivedUrl

    override func viewDidLoad() {
    super.viewDidLoad()

    let myAppDelegate = UIApplication.shared.delegate as! AppDelegate
    print("receivedUrl \(myAppDelegate.receivedUrl!)")
    //url Parsing & getting rid off urlScheme
    let urlToLoad = URL(string: "\(myAppDelegate.receivedUrl!.host! + ":" + myAppDelegate.receivedUrl!.path)")!
    print(urlToLoad)
    let urlRequest = URLRequest(url: urlToLoad)
    webView.load(urlRequest)
}

否则，您需要以正确的方式解析它，例如字典，以便为您的网址中的相应键分配动态值，从而将"?"添加到您的urlToLoad，然后再尝试像在webView控制器中那样追加url.query。

您可以使用深层链接来完成此操作。

首先define a custom URL scheme

一旦您的应用响应自定义方案my-app://，您就可以从todayViewController打开您的应用。

@IBAction func goButton(_ sender: Any) {

    let myAppUrl = URL(string: "my-app://openurl/\(yourURL.addingPercentEncoding(withAllowedCharacters: .urlPathAllowed))")!
    extensionContext?.open(myAppUrl, completionHandler: { (success) in
        if (!success) {
            print("error: failed to open app from Today Extension")
        }
    })
}

在您的应用中，就像上一个链接中所描述的那样，您必须在应用代理中实施

func application(_ app: UIApplication, open url: URL, 
  options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool

在此方法中，网址将是您在应用扩展程序中创建的网址。这意味着它将是my-app://openurl/{the url with percent escaping}您必须解析此URL，初始化包含webView的视图控制器并传递要打开的URL。
