I have set up the customized Hint for my UIButton. What I expect is that when single-tapped, the button will read the Hint; when double-tapped the Hint will not sound, but the normal button action will happen.

But in fact, the Hint is read again on double-tap, while at the same time the normal button action happens. The re-reading would be annoying enough, but the normal action is to play a different sound. They wind up being combined. Yecch!

One would think the UIAccessibilityTraitPlaysSound would be the thing to use, but it has no effect. I could just use AllowsDirectInteraction, but would then lose the Hint. In any case, the re-reading of the Hint on double-tap is just wrong. IMHO.

If I recall correctly, the plays sound trait refers to the activation sound (that sounds like a brief "blip"), and is used for an element that wants to play its own activation sound.

If you are playing anything more/longer than an activation sound, I think that you should be using the starts media session trait instead.

UIAccessibilityTraitStartsMediaSession

The accessibility element starts a media session when it is activated.

You can use this trait to silence the audio output of an assistive technology, such as VoiceOver, during a media session that should not be interrupted. For example, you might use this trait to silence VoiceOver speech while the user is recording audio.

    That's it. The docs are pretty scanty on this. But I should know that means to just try everything. Thanks! – Andrew Duncan Dec 15 '15 at 22:46
  • Thank you so much! But what if I want to call UIAccessibility.post(notification: .announcement ...) on button tap? (I need to declare if the answer was correct or no without repeating it again) – f3dm76 Apr 03 '20 at 10:48
