VoiceService in iOS

I have a question about understanding event changes in iOS when VoiceOver is enabled. I'm developing some app for blind people.

Unfortunately there is not TTS support on iOS, differently from the Mac OS SDK where you can use NSSpeechSynthesizer objects.

I found VoiceService the is not public. So, in conclusione it seems that no API for speak text is available on iOS.

The question is: How can I notify the user about data processing end?

Here is a user case: User push button, the app make some calculus/process, than should return the result. In Mac this is easy you use speakString:@"Result".

But how can I tell VoiceOver to announce the result??

Excuse me if I was too contort :-)

Thank you very much...

Solution

  • You could use this

    if (UIAccessibilityIsVoiceOverRunning()) {
   UIAccessibilityPostNotification(UIAccessibilityAnnouncementNotification,
                                   @"Result has been computed.");
}
