uibutton

问题 I have a UIButton that is sometimes blank (no text or image). When it is blank, I want VoiceOver to skip over it. I've tried the following things, but none of them do the job -- the button still gets highlighted as the user swipes through the views: Set the button and all of its subviews' .accessibilityTraits to UIAcessibilityTraitNotEnabled.

问题 I started developing apps for Apple TV and I have this problem whit buttons.

问题 I’m not asking for givemesamplecodenow responses, just a nudge in the right direction would be much appreciated. My searches haven’t been any good.

But I can't find it and any help would be much appreciated. 回答1: I don't
