暂停画外音时的异常 [英] Exception when pausing voice over

问题描述

我尝试暂停画外音并出现异常:

I try to pause voice over and get an exception:

UIAccessibilityPostNotification(UIAccessibilityPauseAssistiveTechnologyNotification,UIAccessibilityNotificationVoiceOverIdentifier)

UIAccessibilityPostNotification(UIAccessibilityPauseAssistiveTechnologyNotification, UIAccessibilityNotificationVoiceOverIdentifier)

'NSInvalidArgumentException'，原因:'您必须传递暂停的辅助技术.参见 UIAccessibilityConstants.h有效值的列表.'

'NSInvalidArgumentException', reason: 'You must pass the identifier of the assistive technology to pause. See UIAccessibilityConstants.h for the list of valid values.'

怎么了?谢谢！

推荐答案

您必须使用 UIAccessibility.AssistiveTechnologyIdentifier 像:

You must use an UIAccessibility.AssistiveTechnologyIdentifier like:

   UIAccessibility.post(notification: .pauseAssistiveTechnology,
                         argument: UIAccessibility.AssistiveTechnologyIdentifier.notificationVoiceOver)
