#### accessibilityViewIsModal (iOS)
A Boolean value indicating whether VoiceOver should ignore the elements within views that are siblings of the receiver.
For example, in a window that contains sibling views `A` and `B`, setting `accessibilityViewIsModal` to `true` on view `B` causes VoiceOver to ignore the elements in the view `A`.
On the other hand, if view `B` contains a child view `C` and you set `accessibilityViewIsModal` to `true` on view `C`, VoiceOver does not ignore the elements in view `A`.
#### onAccessibilityTap (iOS)
Use this property to assign a custom function to be called when someone activates an accessible element by double tapping on it while it's selected.
