when VoiceOver is on, is there a way an app can detect a single-finger (left-right)swipe?

Question

When VoiceOver is active on an iOS device, the single-finger swipe(left or right) gesture allows users to browse the different elements in the view. Is there a way to detect if

Answer 1

I ended up creating a category/extension on UIView and overriding accessibilityElementDidBecomeFocused().

Here I can get a global hook, which gets called every time the accessibility state has changed.

Swift example:

extension UIView {

//MARK: Accessibility

    override public func accessibilityElementDidBecomeFocused() {
        super.accessibilityElementDidBecomeFocused()

        UIApplication.sharedApplication().sendEvent(UIEvent())
    }
}
