问题 I'm attempting to add support for Voice Over accessibility in a puzzle game which has a fixed board. However, I'm having trouble getting UIAccessibilityElements to show up. Right now I'm overriding accessibilityElementAtIndex , accessibilityElementCount and indexOfAccessibilityElement in my SKScene. They are returning an array of accessible elements as such: func loadAccessibleElements() { self.isAccessibilityElement = false let pieces = getAllPieces() accessibleElements.removeAll

问题 With VoiceOver enabled a user can use a 3 finger swipe gesture to scroll TableViews. VoiceOver verbally announces to the user a phrase indicating their location on the tableview i.e. the rows that are visible such as "Rows 1 to 4 of 5". I would like to override this verbal prompt and get voiceover to announce something else to the user. 回答1: You can't change only the message. You will have to override accessibilityScroll: and do the scrolling and then post the scroll announcement (at least I

问题 I have a UITextView set up with an updating log that I'm trying to make accessible. I'd like to have it so, with Voice Over enabled, and entire paragraph is selected and read. Currently I can either set the accessibilityTrait and have the entire view read aloud in one giant block, or not set the accessibilityTrait set and have only a single line selected at a time. Is there a way to block paragraphs together for VoiceOver? Here is the code I'm currently using: NSString *string =

问题 I'm looking to implement something for voiceover users that is similar to how Apple handles the miniplayer in their Music app. In the miniplayer, there are a number of accessibility elements: the album artwork, the track metadata, the play and forward buttons. When a user first selects an element within the miniplayer, the voiceover reads "Miniplayer; double tap to expand the miniplayer" before giving the label for the element selected. But if you navigate between elements in the miniplayer,

问题 There are 3 buttons in my app, when voice over is turned on and the user swipes to the right, the next button is selected. Note - The button accessibility focus is different from button pressed. Reason for asking - I want the app to announce "AAA" when the button 1 is selected and "BBB" when button 1 is pressed. Questions How can the above be achieved ? Is there a way to call a method when a button is selected. 回答1: The View (in this case button) needs to implement the protocol

问题 I have an element (an imageView) which shows a number. I want the voice over user to swipe up to increment and swipe down to decrement. There are a total of six numbers (images) and each number shoes different content on screen. For that intent I made the view adjustable: imageView.accessibilityTraits = .adjustable I also implemented the following methods: override func accessibilityIncrement() { print("increment") } override func accessibilityDecrement() { print("decrement") } However, when
