如何从MODAL视图控制器隐藏iPad键盘？ [英] How to HIDE the iPad keyboard from a MODAL view controller?

问题描述

我正试图将iPad键盘隐藏在模态视图控制器中，但它不起作用。我已经尝试过resignFirstResponder但是如果我们在一个模态视图控制器中那没有任何影响。我在非模态UINavigationController中尝试了resignFirstResponder，它具有完全相同的UIViewController，并且键盘正确隐藏。

I'm trying to hide the iPad keyboard from a modal view controller but it doesn't work. I have tried resignFirstResponder but that doesn't have any affect if we are in a modal view controller. I tried resignFirstResponder in a non-modal UINavigationController with the very same UIViewController and the keyboard hides correctly.

有谁知道如何解决这个问题？

Does anyone know how solve this problem?

谢谢。

[更新]我的代码看起来有问题，因为resignFirstResponder确实有效（我做了一个简单的测试用例使用我的代码）。但我仍然不知道问题是什么。

[Update] it looks like there's something wrong with my code because the resignFirstResponder does work (I made a simple test case instead of using my code). But I still don't know what the problem is.

推荐答案

这是因为我使用的是UIModalPresentationFormSheet。所有其他的都按预期工作......浪费了几个小时。

It was because I was using UIModalPresentationFormSheet. All of the other ones work as expected.... Wasted several hours on that.
