Xamarin.Forms iOS 项目在启用链接和 Auth0.OidcClient 和 SfListViewRenderer 的情况下启动时崩溃

Question

我一直在尝试查找我的 AppDelegate.cs 中似乎由 Auth0.OidcClient.ActivityMediator 和 Syncfusion.ListView 引起的崩溃.XForms.iOS.SfListViewRenderer 。仅在启用链接的发布模式下启动时才会发生崩溃（仅使用 Link Framework SDK 或 Link All 会发生崩溃）。我还发现，如果我删除以下行之一：

SfListViewRenderer.Init(); //Problem line 1.

或：

ActivityMediator.Instance.Send(url.AbsoluteString); //Problem line 2.

然后崩溃消失了。只有启用了这两行并启用了链接，才会发生崩溃。这是我的 AppDelegate.cs：

         {

             Forms.Init();
    
             IQKeyboardManager.SharedManager.Enable = true;

             UIApplication.SharedApplication.StatusBarHidden = true;
    
             LoadApplication(new App());
    
             return base.FinishedLaunching(app, options);
         }
    
         //This method is required for using the OidcClient on iOS.
         public override bool OpenUrl(UIApplication application, NSUrl url, string sourceApplication, NSObject annotation)
         {
             ActivityMediator.Instance.Send(url.AbsoluteString); //Problem line 2.
    
             return true;
         }
     }
 }

我已尝试删除和恢复软件包。清空 bin/ 和 obj/ 文件夹并重新排列各种 Syncfusion 元素的初始化顺序。我在 iOS 14.8 iPad 和 iOS 15.1 iPad 上遇到了崩溃。

有人知道这里会发生什么吗？有人对故障排除有任何建议吗？

我找到了解决方案。据我了解，动态注册商已被删除，导致此异常：ObjCRuntime.RuntimeException: Can't register the class Plugin.BLE.BleCentralManagerDelegate when the dynamic registrar has been linked away。我不确定为什么会发生这种情况，但在 Additional mtouch arguments 中添加以下标志修复了崩溃：--optimize=-remove-dynamic-registrar
