[英]Open Safari from my Today Extension (widget) within my app
I have a Today Extension with a text field. 我有一个带有文本字段的Today Extension。 I want to use the contents of the text field as a URL to open a browser within my app.
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。
This is my TodayViewController.swift for my widget 这是我的小部件的TodayTodayViewController.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")
}
})
}
You could use @Giuseppe_Lanza solution and parse url that you receive from Today Extension Widget. 您可以使用@Giuseppe_Lanza解决方案并解析从Today Extension Widget收到的URL。 However, I would show an example where your url have a static components and looking for a path such as
https:/www.apple.com/homepod
or https:/www.apple.com/iphone
based on user's input in the textField: 但是,我将显示一个示例,其中您的url具有静态组件,并根据textField中用户的输入来查找诸如
https:/www.apple.com/homepod
或https:/www.apple.com/iphone
类的路径:
1- URL Scheme: myAppName
1- URL方案:
myAppName
2- Add this to open your app with widget 2-添加它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 3- AppDelegate
Define a variable and pass received url to webViewController, will parse url there. 定义一个变量并将接收到的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)
}
Make sure to make add an identifier for this segue under the attributes inspector as
toDeepLink
.确保在属性检查器下添加此
toDeepLink
的标识符为toDeepLink
。
4- WebView & parsing url Now you can get the receivedUrl like this 4- WebView和解析URL现在,您可以像这样获取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)
}
Else, you need to parse it in a proper way like dictionary to assign dynamic values to respective keys in your dictionary and hence to your url or append "?"
否则,您需要以适当的方式(例如字典)对其进行解析,以将动态值分配给字典中的各个键,从而分配给您的url或附加
"?"
to your urlToLoad
just before you attempt to append url.query as I did in the webView controller. 就像我在webView控制器中一样尝试将url.query附加到
urlToLoad
之前。
You can do this by using deep linking. 您可以通过使用深层链接来实现。
First define a custom URL scheme 首先定义一个自定义URL方案
Once your app responds to the custom scheme my-app://
you can open your app from your todayViewController. 一旦您的应用程序对自定义方案
my-app://
做出响应,您就可以从todayViewController中打开您的应用程序。
@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")
}
})
}
In your app, just like described in the previous link you will have to implement in your app delegate 在您的应用程序中,就像上一个链接中所述,您将必须在应用程序委托中实现
func application(_ app: UIApplication, open url: URL,
options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
in this method, the url will be the one you created in your app extension. 在这种方法中,网址将是您在应用扩展程序中创建的网址。 Meaning it will be
my-app://openurl/{the url with percent escaping}
You will have to parse this url, initialise the view controller that contains the webView and pass the url to be opened. 这意味着它将是
my-app://openurl/{the url with percent escaping}
您将必须解析该网址,初始化包含webView的视图控制器,然后传递要打开的网址。
