问题
When I set isAccessibilityElement = NO on a view that contains subviews with isAccessibilityElement = YES, VoiceOver still detects them.
I need to switch off accessibility for an entire view hierarchy that must be handled differently by VoiceOver. How can I achieve this without having to loop through every single item in the object graph and mess with it's setting?
回答1:
self.accessibilityElementsHidden = YES;
This makes all subviews hidden from accessibility.
回答2:
I would try setting the accessibilityElementsHidden property of the main view to YES. If that does not what you want, I would try overriding the UIAccessibilityContainer methods on the main view to return 0 children.
回答3:
Just set the accessibilityElementsHidden property.
