16. Swipe Based Navigation

17. Default
Experience
With
VoiceOver

19. Swipe Navigation
• Animated transition between views
• Next and Back flow with every screen
• Eliminates navigation buttons
• No buttons? Accessibility?
• Have I reached the end of the screen?

20. Detect Accessibility ON
• UIAccessibility kit provides two methods
• UIAccessibilityIsSwitchControlRunning
• UIAccessibilityIsVoiceOverRunning
• True == Show Navigation Buttons

21. State Change Notification
• User enables VoiceOver while on a screen
• Detect the status change
• UIAccessibilitySwitchControlStatusDidChange
Notification
• UIAccessibilityVoiceOverStatusChanged
• Refresh screen and insert navigation buttons

22. TurboTax Helper Function
• How can we refactor code to detect any
accessibility related settings and address them
together?
• Helper function to the rescue !
• NSNotificationCenter adds observers to track any
settings that may require us to show buttons.
• This is an OR logic. Example - if voice over OR
switch control status changed, display buttons.
