voiceover

问题 When a UITableView is editable, its UITableViewCells allow the user to perform custom actions when VoiceOver is on. The user can hear the available actions by swiping up or down while the VoiceOver cursor is on the cell and then invoke the actions by double tapping anywhere on the screen. There are only two actions available in my cells: Delete (invokes the usual cell deletion) and Default (invokes a tap on the cell). My question is two-fold: Is there a way of adding custom VoiceOver actions

问题 iOS 8.x VoiceOver announces dimmed instead of disabled for buttons that have been disabled. Is there a way to programmatically get VoiceOver to say "disabled" instead of "dimmed"? 回答1: There are ways to do what you want, but you absolutely should not use them. The announcement "Dimmed" occurs, when the User Interaction Enabled trait is set to NO . This is the way VoiceOver users are use to on screen, focusable, but disabled elements being announced. Forcing your app to behave in another

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'm having an issue with moving the voiceover cursor to a specific element on viewDidAppear. I followed Apple's guidelines for focusing on a specific element, in this case a dismiss button, but the cursor ends up elsewhere Here is my Code: - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; UIAccessibilityPostNotification(UIAccessibilityScreenChangedNotification, self.dismissButton); } Any help, ideas, would definitely be appreciated! thank you so much. 回答1: If I remember

问题 Is there any way to set accessibilityHint for back button? I would like that voiceover read first "Back Button" and after this Hint e.g. "Double tap to go back to select a building screen" I'm trying to do it that way but it's not working: in viewDidLoad: [super viewDidLoad]; // back button without any text just back arrow UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil]; self.navigationItem

问题 When VoiceOver is active on an iOS device, the single-finger swipe(left or right) gesture allows users to browse the different elements in the view. Is there a way to detect if a user used the single-finger swipe gesture when using voiceover? 回答1: You might be asking either of 2 things: You want to know when the VoiceOver user successfully issued the single-finger swipe left/right gesture to VoiceOver - VoiceOver will process ("steal") the gesture from your code and do its thing (move

问题 In our current UI, next to certain labels, we have a help-tip button that when clicked, explains the details of what the label references. As such, VoiceOver identifies these two items as separate accessibility items. However, when using accessibility, we're hoping we can just do everything in the label itself. This way when the label gets focused, the user will here 'Account value, $20 (the accessibilityLabel), double-tap for help (the accessibilityHint)' However, unlike a button, a label

问题 When I try to test my app on my 4.3.2 device with VoiceOver turned on I get the following warnings: warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.2 (8H7)/Symbols/System/Library/AccessibilityBundles/AccessibilitySettingsLoader.bundle/AccessibilitySettingsLoader (file not found). warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.2 (8H7)/Symbols/System/Library/AccessibilityBundles/UIKit.axbundle/UIKit (file

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,
