Showing a blocked UIAlertView in ViewDidAppear Method on iOS 7 with Xamarin.iOS does not work -

if try show blocked alertview in viewdidappear method on ios 7, won´t able dismiss alertview. no touch events reach alertview. button of view highlighted, nothing happen. if run same code on ios < 7, work fine.

here example code:

    public override void viewdidappear(bool animated)     {         base.viewdidappear(animated);          var alert = new uialertview("title", "message", null, "ok");         alert.dismissed += (sender, args) => result = true;         alert.show();          while (!result)             nsrunloop.current.rununtil(nsdate.fromtimeintervalsincenow(0.1));     } 

i using xamarin.ios version 6.4.3.0 apple sdk 6.1. have same problems alpha of xamarin.ios 6.9.6.0 , apple sdk 7.0.

can tell me problem is?

thanks help.

it's not idea use nsrunloop block ui execution, there better way of doing it.

you can make use async/await pattern wait user press uialertview button. here's sample can use: https://gist.github.com/prashantvc/6725882
