Why should the selector for UIAccessibilityCustomAction object return BOOL? What difference does it make whether it's true or false?

Ah finally I found that little note in Apple's documentation...

All special VoiceOver gesture methods return a Boolean value that determine whether to propagate through the responder chain. To halt propagation, return YES; otherwise, return NO.

Not as mysterious as expected.

  • Did you manage to pass the a parameter within the selector using UIAccessibilityCustomAction ? I'm trying to do this for couple of days – Pavlos Feb 12 '18 at 11:10
  • What `"the a parameter"` do you mean exactly? – dobranoc Feb 12 '18 at 14:15
  • actually I wanted to use swipe to delete a cell in a list and the VoiceOver wasn't working properly with it. I meant about passing the indexPath.row using the selector but this was not an option and now I got my problem solved here: https://stackoverflow.com/a/48689384/4723935 – Pavlos Feb 12 '18 at 14:27
