1. before iOS 13

AppDelegate.swift

// For earlier versions, use the URL Scheme to start the App when it is not started.
// Add application(app: open: options:) method, don't use this, iOS 10.3.1 test
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    if letsechme = launchOptions? [UIApplicationLaunchOptionsKey.url] as? URL{
          DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
            let alert = UIAlertController.init(title: "BBB", message: url.absoluteString, preferredStyle: .alert)
            alert.addAction(UIAlertAction.init(title: "cancel", style: .cancel, handler: nil))
            self.window? .rootViewController? .present(alert, animated:true, completion: nil)}// Move to openUrl for processing
        // _ = self.application(application, open: sechme)}}Copy the code
// iOS 10.3.1 Active/Not active
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
            let alert = UIAlertController.init(title: "AAA", message: url.absoluteString, preferredStyle: .alert)
            alert.addAction(UIAlertAction.init(title: "cancel", style: .cancel, handler: nil))
            self.window? .rootViewController? .present(alert, animated:true, completion: nil)}return true
}
Copy the code

After testing, only application(app: open: options:) method is used in iOS 10.3.1, which can deal with two cases of app being started and not being started.

Using both methods together, well, buggy, will be called. Try 🤨. Error welcome correction 👏.

2. The iOS 13.3

1. The App is not started

// iOS 13 not active
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    if #available(iOS 13.0, *) {
        guard let _ = (scene as? UIWindowScene) else { return }
        for context in connectionOptions.urlContexts{
            DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
                let alert = UIAlertController.init(title: "not active", message: context.url.absoluteString, preferredStyle: .alert)
                alert.addAction(UIAlertAction.init(title: "cancel", style: .cancel, handler: nil))
                self.window? .rootViewController? .present(alert, animated:true, completion: nil)}}}else {
        // Fallback on earlier versions}}Copy the code

2. The App has been started

@available(iOS 13.0*),// iOS 13 active
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    for context in URLContexts{
        DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
            let alert = UIAlertController.init(title: "active", message: context.url.absoluteString, preferredStyle: .alert)
            alert.addAction(UIAlertAction.init(title: "cancel", style: .cancel, handler: nil))
            self.window? .rootViewController? .present(alert, animated:true, completion: nil)}}}Copy the code

For iOS13.3 testing, write local script for scene:openURLContexts: unified processing (😂)
