问题 Hello I am learning using MSAL but met a wired issue. I totally followed the tutorial, and I am using the sample code. But I still got this exception building the client in App.xaml.cs : microsoft.identity.client.msalclientexception: the application cannot access the ios keychain for the application publisher (the team id is null). this is needed to enable single sign on between applications of the same publisher. this is an ios configuration issue. see https://aka.ms/msal-net-enable-keychain

It seems to be working in most cases, but I have noticed that tapping the last line of an attributed text creates inconsistent results. public static bool DidTapRange(this UITapGestureRecognizer recognizer, UILabel label, NSRange range) { using (var ts = new NSTextStorage()) { var lm = new NSLayoutManager(); var tc = new NSTextContainer(new CGSize(label.Frame.Width, double.MaxValue)); lm.AddTextContainer(tc); ts

问题 I'm trying in Xamarin to add a marker in the center of the map that marker will be fixe and can not be dragged, the map below that marker can be dragged normally. I need to get the position of the map that was chosen by the user, I searched a lot for the internet and found nothing that could help me.

问题 Just updated to the lastest version of Xamarin studio and Xamarin.iOS. Now I am getting this error: Got a SIGABRT while executing native code.
