Question

我正在为Android和iOS开发一个带有Xamarin.Forms的应用程序。当我进入类似http://app.myapp.io/user/reset-password/{some_hash}的网址时，我会在一个特殊屏幕中打开该应用，该屏幕允许用户为其帐户设置新密码。

在Android中，我通过使用自定义意图过滤器实现此目的，将方案设置为http，将主机设置为app.myapp.io。我想在iOS中做同样的事情。但是当您在iOS中注册应用程序链接时，AFAIK会在您的Info.plist文件中注册自定义方案。这是我在Info.plist文件中的自定义方案。

这是我的AppDelegate.cs

{
    // The UIApplicationDelegate for the application. This class is responsible for launching the 
    // User Interface of the application, as well as listening (and optionally responding) to 
    // application events from iOS.
    [Register("AppDelegate")]
    public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate, IDeviceStorage
    {
        const string HOCKEYAPP_APPID = "ef71d53e56044baa813c2381b291c355";

        #region IDeviceStorage implementation
        public string LoadString(string key, string def = null)
        {
            string value = NSUserDefaults.StandardUserDefaults.StringForKey(key);
            if (value == null)
                return def;
            else
                return value;
        }

        public void SaveString(string key, string value)
        {
            NSUserDefaults.StandardUserDefaults.SetString(value, key);
            NSUserDefaults.StandardUserDefaults.Synchronize();
        }
        #endregion

        //
        // This method is invoked when the application has loaded and is ready to run. In this 
        // method you should instantiate the window, load the UI into it and then make the window
        // visible.
        //
        // You have 17 seconds to return from this method, or iOS will terminate your application.
        //
        public override bool FinishedLaunching(UIApplication app, NSDictionary options)
        {
            if (!Resolver.IsSet) SetIoc();

            global::Xamarin.Forms.Forms.Init();
            SvgImageRenderer.Init ();
            LoadApplication(new App());

            return base.FinishedLaunching(app, options);
        }

        public override bool OpenUrl (UIApplication app, NSUrl url, string sourceApp, NSObject annotation)
        {
            var resetLinkHash = string.Empty;
            if (url.BaseUrl.Host.Equals ("app.myapp.io")) {
                    if (!Resolver.IsSet) SetIoc();

                    global::Xamarin.Forms.Forms.Init();

                    LoadApplication(new App(url.LastPathComponent));
                    return true;

            }
            LoadApplication(new App(url.LastPathComponent));
            return true;
        }

        private void SetIoc()
        {
            TinyIoCContainer.Current.AutoRegister ();
            var container = TinyIoCContainer.Current;
            container.Register<IDeviceStorage>(this);
            container.Register<IXFormsApp> (new XFormsAppiOS ());
            container.Register<ISecureStorage, SecureStorage> ();
            Resolver.SetResolver(new XLabs.Ioc.TinyIOC.TinyResolver(container));
        }
    }
}

这是我的Main.cs

{
    public class Application
    {
        // This is the main entry point of the application.
        static void Main(string[] args)
        {
            // if you want to use a different Application Delegate class from "AppDelegate"
            // you can specify it here.
            UIApplication.Main(args, null, "AppDelegate");
        }
    }
}

而且，现在这在iOS上无效，无论是否在开始时尝试使用http。

如果有人可以指出我正确的方向，我会很感激。对我来说，通过匹配网址来启动应用程序非常重要，例如在网页上添加一些<meta/>标签，html将无法正常工作，因为我无法访问服务器。

Answer 1

与Android不同，iOS上的URL方案只能注册到一个应用程序。这不适合您的原因是因为http不是您的应用可以注册自己在iOS上使用的可用网址方案。

实现此功能的方法是Universal Links，这是一项新的iOS 9+功能。这允许您仅在特定域上为http / https URL注册您的应用程序。但是，您需要访问服务器，因为您需要进行一些服务器端更改以证明您控制了相关域。如果这是不可能的，请考虑使用免费服务，例如Branch.io（完全披露：我是团队）来处理您的链接。

Xamarin.Forms - 链接到http方案url的iOS应用程序不起作用
