【问题描述】：
我正在尝试在 Xamarin Forms 应用程序中启用“Link All”。它已在 Android 中成功完成。但是对于，它是 iOS 版本，我得到了一个运行时错误。
应用程序刚刚启动并崩溃。
在iOS → Main.cs → UIApplication.Main (args, null, "AppDelegate");
我该如何解决这个问题？
附加崩溃日志。

【问题讨论】：
-
您是否从 AppDelegate 分配任何根视图控制器？或者，如果您的 Xamarin Forms 应用程序确实初始化了任何 MainPage？您可以从 AppDelegate 初始化 Empty 视图控制器，然后打开 Xamarin Forms 应用程序吗？除了从 AppDelegate/Xamarin Forms 应用程序打开的当前页面之外，您还能打开任何其他页面吗？这些是您之前可能想要测试的所有可能性。

@NirmalSubedi我会尝试所有这些并让你知道

尝试从它应该工作的选项中链接使用 SDK 程序集。
