Set accessibility badge on a tabbarItem

Question

I have a tabbar application. If there is a badge on a certain tab VoiceOver pronounces N items. I'd like to make it pronounce N messages.

How do I do that?

Answer 1

I had a similar problem, it seems that UITabBarViewController.tabbar is handling accessibility differently than other views. So my solution was placing another uiview above the badge as a subview of [tabbar superview] and adding accessibility to this view:

At viewDidLoad:

self.badgeAccessibilityView = [[UIView alloc] init];
//use tabBarView.frame to calculate
self.badgeAccessibilityView.frame = frameAccordingToBadgeLocation;
self.badgeAccessibilityView.userInteractionEnabled = YES;
self.badgeAccessibilityView.isAccessibilityElement = YES;
[self.tabBarView.superview addSubview:self.badgeAccessibilityView];

On badge value change:

self.badgeAccessibilityView.accessibilityLabel = 
   [NSString stringWithFormat:@"%d Notifications", badgeValue];
