Hi,
I'm currently working on making our game Shreeder Chess for iOS accessible. It works great so far with 4.x (in fact much better than I'd ever expected), but some questions come up when regarding backward compatibility.
As I want to have a voice announcing moves when they get played, I use
if (UIAccessibilityIsVoiceOverRunning()) {
NSString *text = ...;
UIAccessibilityPostNotification(UIAccessibilityAnnouncementNotification, text);
}
I guess the wrapping makes only sense if the computation of "text" is expensive? As the cost isn't too much overhead I could easily leave this out (as this is only 4.x feature).
The real problem goes with the announcement itself, as UIAccessibilityAnnouncementNotification is only available since 4.0. Is there any way to make announcements in 3.x?
Thank you,
Eiko
