问题 I have an apple account with the admin role. Whenever I'm trying to add an apple account to visual studio, it displays "There was an error while trying to log in: A server with the specified hostname could not be found". I updated Visual Studio 2017 also. Still, it displays the same error. Please help me. 回答1: As @LeonLu mentioned, it might be a problem with the non-paid version of account. This is stated in the Microsoft docs: https://docs.microsoft.com/en-us/xamarin/cross-platform/macios

问题 I'm mainly developing for Android, so I know one can access the external storage of an Android device in Xamarin.Forms using Android.Content.Context.GetExternalFilesDir . I know its possible to access the internal storage platform-independently using Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) , but is it also possible to do the same for external storage? I know the use case might be prettty limited, as iOS doesn't allow any non-jailbreaked access to the file

问题 I'm displaying an image within my content pages such that its height is a fixed percentage of the page height. I do this using a grid with star unit row height. However, when the content pages are placed within a TabbedPage, the total grid height seems to be that of [the screen minus the tab bar height], so as a consequence, the image appears a bit shorter. If I could access the tab bar height within my content pages, it would be a simple adjustment to the percentage. Question: 1) How do I

问题 I'm developing a Xamarin.Forms app, and setting up Azure AD B2C for auth. I'm following the official tutorial. Everything works flawlessly for Andorid, but I'm facing an issue with th iOS project. I've setup everything mentioned in the tutorial but that is not enough.

问题 I have an iOS app developed in Xamarin. When the app does not have permission to access the microphone, if the user tries to access the microphone from the app, I check the settings using AVAudioSession.SharedInstance().RequestRecordPermission (delegate(bool granted)) and display a message. Now I need to do the same if the app does not have permission to access the camera. I need to check if permission is granted for camera and display a message accordingly. How can I do this? 回答1: Did you

问题 So for Android when the master page of a master-detail page is shown the master page is covered with a "black dim" view so it is easy to differentiate the two pages with the eye. In iOS the detail page is not dimmed so it is tougher to differentiate the views. Is there a way to overlay the details page with a BoxView or Frame that is "black translucent" so it dims the page in similar fashion to Android. I have tried many different colors and opacities of a box view but they all completely

问题 I'm trying to parse an xml document using the following: XmlDocument doc = new XmlDocument (); doc.LoadXml (myXMLstring); I get the error: The type or namespace name 'XmlDocument' could not be found. Are you missing an assembly reference? ..even though I have using System.Xml; I'm not sure what an assembly reference is. I'm using Xamarin Studio. I see there are several folders for references. In the references folder for the base project I don't see an entry for System.Xml But in individual
