我们有一个带菜单的应用。有一个UIBarButton可以点击打开它。顶视图滑开以显示菜单。当VoiceOver打开时,我们会收到以下错误。我假设因为
的区域

). If this happened right around a screen change, it might be okay, but otherwise this is probably a bug.

我添加了UIAccessibilityPostNotification(UIAccessibilityLayoutChangedNotification,nil);但我仍然得到错误。
我应该关注这个问题吗?
答案 0 :(得分:1)
您正在使用UIAccessibilityLayoutChangedNotification
,用于通知UIView
的元素或部分内容的布局已更改。尝试使用UIAccessibilityScreenChangedNotification
。
如果你的tableView滚动,你可能想要使用UIAccessibilityPostNotification(UIAccessibilityPageScrolledNotification, [self.tableView indexPathsForVisibleRows]);
,这样每次tableView滚动时,焦点都在tableView的第一个单元格上。
