xamarin_中的SIGABRTCrash

Question

我正在用Xamarin iOS和Android开发一个应用程序。在少数情况下，iOS版本（非android）通过bug报告系统报告此问题：

我不明白这是Mono/Xamarin的问题还是我的代码。

任何想法？

在注释中按请求更新这是Main的代码

public class Application
    {
        // This is the main entry point of the application.
        static void Main (string[] args)
        {
            Xamarin.Insights.Initialize ("xxxxxxxxx"); //id of the app on insight
            UIApplication.Main (args, null, "AppDelegate");
        }
    }

这是我的AppDelegate

    [Register ("AppDelegate")]
    public class AppDelegate : UIApplicationDelegate
    {
        // class-level declarations

        public override UIWindow Window {
            get;
            set;
        }

        public static UIStoryboard Storyboard = UIStoryboard.FromName ("TouristAppStoryBoard", null);
        public static UIViewController initialViewController;

        public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
        {

            Window = new UIWindow (UIScreen.MainScreen.Bounds);

            initialViewController = Storyboard.InstantiateInitialViewController ();
            Window.RootViewController = initialViewController;

            var navController = Window.RootViewController as UINavigationController;
            navController.NavigationBar.TitleTextAttributes = ViewUtility.GetAttributesForTitleNavigationBar ();

            Window.MakeKeyAndVisible ();
            return true;
        }

        public override void OnResignActivation (UIApplication application)
        {
        }

        public override void DidEnterBackground (UIApplication application)
        {

            LocationManager.GetIstance ().StopLocationUpdates ();
            var taskID = UIApplication.SharedApplication.BeginBackgroundTask( () => {});
            Task.Factory.StartNew ( () => {
                ComuniDb.GetIstance().Manutenzione();
                UIApplication.SharedApplication.EndBackgroundTask(taskID);
            });
        }

        public override void WillEnterForeground (UIApplication application)
        {    
            LocationManager.GetIstance ().StartLocationUpdates ();
        }
    }
}

我的应用程序不小，我希望你找到你想要的。

我发现了问题。问题记录在设备日志中，但不记录在崩溃日志中。这对我来说很愚蠢（设备日志比崩溃日志有更多的信息？），但是我发现了错误并修复了它。
