Join Kevin Favro for an in-depth discussion in this video VoiceOver gestures, part of iOS App Development: Accessibility.
- [Narrator] VoiceOver defines five special gestures…for triggering app-specific actions.…The Escape gesture is a two finger, Z shaped gesture…that dismisses a modal dialog, or goes back…one level in the navigation hierarchy.…The Magic Tap is a two finger, double tap…that performs the most intended action.…A Three-finger scroll is a three finger swipe…that scrolls content vertically or horizontally.…We've been using this gesture to pan around…our Map view and to reach the bottom of our Detail screen,…to get to our image thumbnails.…
The Increment gesture is a one finger swipe up…that increments a value in an element…and a Decrement gesture is a one finger swipe down…that decrements a value in an element.…We can use these gestures to perform tasks…that are specific to our application.…For example, the Music app uses the Magic Tap…to play and pause playback anywhere in the app.…The Camera app uses the Magic Tap…to snap a picture.…Each of these gestures has a corresponding method…that you can over-ride in your views or view controllers.…
