Hello, this is a tidbit for those of you interested in developing for OSX,
I have dug through tons of documentation on VoiceOver accessibility and
submitted several support tickets to apple for assistance and I finally wrote
this function I thought I'd share with everybody:
-(void)speakString:(NSString *)stringToSpeak fromFocusedUIElement:(id)object
{
NSDictionary *announcementInfo = [[NSDictionary alloc]
initWithObjectsAndKeys:stringToSpeak, NSAccessibilityAnnouncementKey, @"High",
NSAccessibilityPriorityKey, nil];
NSAccessibilityPostNotificationWithUserInfo(object,
NSAccessibilityAnnouncementRequestedNotification, announcementInfo);
}
This could easily be expanded on, for instance we could include in this
function a way to tell the object that currently has keyboard focus to assure
that VoiceOver always speaks the string as opposed to you having to figure it
out. We could also add a NSAccessibilityLayoutChanged notification to refresh
the braille display (Although in some very bizarre cases this causes VoiceOver
to speak twice (once with the announcement, once for the layout change). In
other cases the announcement interrupts the layout change notification or visa
versa, I have yet to figure that bit out.
However I felt like this code snippet could do some people good, so there it is.
