从Xamarin Forms App启动另一个IOS App

问题描述

限时删除！！

我正在尝试测试MyApp(CanOpen)中是否存在某个应用程序.如果是这样，我希望打开该应用程序，否则我有一个https地址来打开Web视图.我在开罐测试中得到了错误的回报.我相信我的代码是正确的，但是我不确定在info.plist上.我有一个MyApp的url类型(在info.plist中).我有另一个应用程序(运行状况)的LSApplicationQueriesSchemes条目，但是不确定该引用如何绑定到实际应用程序....非常感谢您的帮助:

I am trying to test if an app is present from MyApp (CanOpen). If so, I wish to open the app, otherwise I have an https address to open a webview. I am getting the false return on the can open test. I believe my code is sound but I am not sure on the info.plist. I have a url type (in info.plist) for MyApp. I have the LSApplicationQueriesSchemes entry for the other app (health), but unsure of how that reference is tied back to the actual app.... Any help is greatly appreciated:

是以下界面:

   public interface IAppHandler
   {
       Task<bool> LaunchApp(string uri);
   }

在模型视图"中，我对实际的处理程序进行去势性调用:

    string appid = @"health://";
    var result = await DependencyService.Get<IAppHandler>().LaunchApp(appid);

    if (!result)
    {
        Show_WebView(url);
    }

在特定于平台的AppHandler中:

public Task<bool> LaunchApp(string uri)
{
    try
    {
        var canOpen = UIApplication.SharedApplication.CanOpenUrl(new NSUrl(uri));
        if (!canOpen)
            return Task.FromResult(false);
        return Task.FromResult(UIApplication.SharedApplication.OpenUrl(new NSUrl(uri)));
    }
    catch (Exception ex)
    {
        return Task.FromResult(false);
    }
}

在info.plist中:

<key>CFBundleURLSchemes</key>
<array>
    <string>MyApp</string>
    <string>com.apple.Health</string>
</array>
<key>LSApplicationQueriesSchemes</key>
 <array>
    <string>health</string>
 </array>

推荐答案

您需要将目标应用的URL方案添加到info.plist文件中，以便使用 canOpen 功能.IE

You need to add the URL Scheme of the target app into the info.plist file in order to use canOpen functionality. i.e
