Question

所以我在visual studio 2017中使用xamarin.forms测试MobileFirst样本，和iPhone模拟器：iPhone 7 Plus iOS 10.3（使用虚拟机）

这是代码：

 public async void ObtainToken()
    {
        try
        {

             WorklightClient = App.WorklightClient;
            WorklightAccessToken accessToken = await WorklightClient.AuthorizationManager.ObtainAccessToken("");

            if (accessToken.Value != null && accessToken.Value != "")
            {
                System.Diagnostics.Debug.WriteLine("Received the following access token value: " + accessToken.Value);
                 await DisplayAlert("Token Value", accessToken.Value, "OK");

                StringBuilder uriBuilder = new StringBuilder().Append("/adapters/javaAdapter/resource/greet");

                WorklightResourceRequest request = WorklightClient.ResourceRequest(new Uri(uriBuilder.ToString(), UriKind.Relative), "GET");
                request.SetQueryParameter("name", "world!");
                WorklightResponse response = await request.Send();

                System.Diagnostics.Debug.WriteLine("Success: " + response.ResponseText);
                DisplayAlert("Greeting Get Request", response.ResponseText.ToString(), "OK");

            }
        }
        catch (Exception e)
        {
            System.Diagnostics.Debug.WriteLine("An error occurred: '{0}'", e);
        }
    }

在访问第一行之前

是craches（在调试中）我不确定它是xamarin错误还是实例化worklighclient 错误：

2017-07-03 12:41:02.461 XamarinMFPTest.iOS[4642:52640] Will try to create a instance if null
2017-07-03 12:53:52.310 XamarinMFPTest.iOS[4642:52640] [FATAL] [WORKLIGHT] App Crash: Crashed with signal SIGSEGV (code SEGV_MAPERR)

ps：此代码正在运行android和uwp

Xamarin.ios应用程序崩溃信号SIGSEGV
