iOS Universal link注意事项

当用户安装APP时，系统会检查存储在服务器上的apple文件，以验证网站是否允许app代表其打开URL

1. 首先配置好apple-app-site-association

2. 将其放入yourdomain.well-known下

3. 通过网址打开https://yourdomain/.well-known/apple-app-site-association 检查apple-app-site-association是否已经配置

4. 检查Apple cdn: app-site-association.cdn-apple.com/a/v1/yourdo… 必须等apple cdn与文件一致时，才是真正的生效，apple cdn一般在24小时内更新

5. 在项目中添加Associated Domains,配置好applinks:yourdomain

6. 在notes 中长按相应link，如一切正常，会出现打开app的选项

7. open app之后的处理

当你的app没有使用Scene时，可以在AppDelete.swift文件中处理

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) {
    // Get URL components from the incoming user activity. 
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb, 
    let incomingURL = userActivity.webpageURL, 
    let components = NSURLComponents(url: incomingURL, resolvingAgainstBaseURL: true) else { 
    return false 
    } 
    // Check for specific URL components that you need. 
    guard let path = components.path, 
    let params = components.queryItems else { 
    return false 
    } 
    print("path = \(path)")
}

当你的app使用Scene时，可以在SceneDelegate.swift文件中处理

//app没有运行，系统会在启动后将Universal link传递到Scene
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // Get URL components from the incoming user activity. 
    guard let userActivity = connectionOptions.userActivities.first, 
        userActivity.activityType == NSUserActivityTypeBrowsingWeb, 
        let incomingURL = userActivity.webpageURL, 
        let components = NSURLComponents(url: incomingURL, resolvingAgainstBaseURL: true) else { 
        return 
        } 
        // Check for specific URL components that you need. 
        guard let path = components.path, 
        let params = components.queryItems else { 
        return 
        } 
        print("path = \(path)")
}

//当app在内存中运行或暂停时点击Universal link时，将链接传递到Scene
func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    // Get URL components from the incoming user activity. 
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb, 
    let incomingURL = userActivity.webpageURL, 
    let components = NSURLComponents(url: incomingURL, resolvingAgainstBaseURL: true) else { 
    return false 
    } 
    // Check for specific URL components that you need. 
    guard let path = components.path, 
    let params = components.queryItems else { 
    return false 
    } 
    print("path = \(path)")
}
