当VoiceOver处于活动状态时，关闭UITextField中的UIKeyboardTypeNumberPad吗? [英] Dismiss a UIKeyboardTypeNumberPad in a UITextField when VoiceOver is active?

问题描述

如何关闭键盘类型为UIKeyboardTypeNumberPad的UITextField?对此问题的可接受的答案建议添加带有关闭按钮的栏作为或在后台收听触摸事件.

How do I dismiss a UITextField with keyboard type UIKeyboardTypeNumberPad? The accepted answer to this question suggests to either add a bar with a dismiss button as an inputAccessoryView or to listen to touch events on the background.

我更喜欢第二种方法，即在包含UITextField的视图上监听触摸事件.但是，如果VoiceOver处于活动状态，则此方法将失败.在这种情况下，您如何resignFirstResponder?

I prefer the second approach, i.e. listen to touch events on the view containing the UITextField. However, this approach fails if VoiceOver is active. How do you resignFirstResponder in that situation?

推荐答案

您需要另一种执行手势的方法.您必须在布局中添加一个按钮.抱歉...

You need an alternative way to perform the gesture. You'll have to add a button to your layout. Sorry...

您应该能够检查VoiceOver是否打开.

You should be able to check whether VoiceOver is on or not.

BOOL UIAccessibilityIsVoiceOverRunning();

您还可以考虑将拍击识别器添加到不可见的UI元素或完全被其他元素覆盖的父视图中.这样，它只能由VoiceOver用户激活.

You could also consider adding a tap recognizer to an invisible UI Element or a parent View that is completely covered with other elements. In this way, it would only be able to be activated by a VoiceOver user.
