How to implement Z Gesture to dismiss an alert or go to previous screen in voiceOver for iOS?

Question

To dismiss an alert while in voiceOver mode, Z gesture is used. Anyone please let me know how to implement that for my project or provide a link which has an example for how to implement that in objective-c?

Answer 1

To dismiss an alert view thanks to the scrub gesture, override accessibilityPerformEscape() in the alert view itself .

I've provided the implementation for this question but it's written in swift : the code isn't complex at all so that you can easily translate it into ObjC.
