Question

Xamarin.iOS UIAccessibility.PostNotification

Palmersjö, Ludvig 1

I cant get UIAccessibility.PostNotification to work.
The following code should read up the text
UIAccessibility.PostNotification(UIAccessibilityPostNotification.Announcement, new NSString(@"Item was saved"));
It says nothing with VoiceOver on. Tried putting this code on ViewWillAppear and on some button click events but nothing works.

@Palmersjö, Ludvig Try the following code.

var toRead = new NSAttributedString("Item was saved", NSDictionary.FromObjectAndKey(new NSNumber(0), UIView.SpeechAttributeQueueAnnouncement));  
UIAccessibility.PostNotification(UIAccessibilityPostNotification.Announcement, toRead);

Note that UIAccessibility.PostNotification applies to "Xamarin iOS SDK 12".
