如何以编程方式与“iPad键盘隐藏按钮”进行交互？

There is a button at bottom right of iPad keyboard which is to hide the keypad.

iPad键盘右下方有一个按钮,用于隐藏键盘。

How can I interact with it programmatically? (get the button then send UIControlEventTouchUpInside to it).

我如何以编程方式与其进行交互? (获取按钮然后发送UIControlEventTouchUpInside)。

Does anyone know this?

有谁知道这个?

[Edit] In my case, the keyboard is shown on a modal view.

[编辑]在我的情况下,键盘显示在模态视图上。

Overriding disablesAutomaticKeyboardDismissal to return NO as below allows you to dismiss the keyboard when you resignFirstResponder, even when your UITextView is on a modal view. You should put this code to your view controller, from which you initiate the keyboard:

覆盖disablesAutomaticKeyboardDismissal以返回NO,如下所示允许您在resignFirstResponder时关闭键盘,即使您的UITextView在模态视图上也是如此。您应该将此代码放入视图控制器,从中启动键盘:

- (BOOL)disablesAutomaticKeyboardDismissal {
    return NO;
}

In general, you would send the resignFirsResponder message to the active input view.

通常,您会将resignFirsResponder消息发送到活动的输入视图。

Something like this? I can't remember where I found this code but I used it to toggle the on-screen keyboard because it would be hidden by default if a bluetooth one was connected.

像这样的东西?我不记得我在哪里找到了这段代码,但是我用它来切换屏幕键盘,因为如果连接了蓝牙键,它会默认隐藏。

- (void) toggleKeyboard(UIKeyboardImpl * keyImpl){

    if (UIKeyboardAutomaticIsOnScreen()) {
        UIKeyboardOrderOutAutomatic();
    } else {
    UIKeyboardOrderInAutomatic();
}

I found where I got this code from. It works fine but the catch is that you need to import the private framework GraphicsServices, which would most likely get your app rejected from the App store.

我找到了从中得到此代码的地方。它工作正常,但问题是您需要导入私有框架GraphicsServices,这很可能会使您的应用程序被App Store拒绝。
