连接蓝牙输入设备时显示软键盘(iPad) [英] display soft keyboard (iPad) when is connected a bluetooth input device

问题描述

我真的很头疼，因为当有蓝牙输入设备连接到 iPad 时，我找不到显示软键盘的方法.我在网上搜索了一下，结果如下:

I'm really bangin' my head because I can't find the way to show the soft keyboard when there's a bluetooth input device connected to the iPad. I made some search on the web and this is the result:

• 一个关于 stackoverflow 的问题，答案很短 我如何检测iPad 上有外接键盘吗?
• 由 erica sadun 为 cydia env 开发的应用程序 http://www.tuaw.com/2010/06/02/hacksugar-bringing-back-the-on-screen-keyboard/

Erica 说诀窍是回答系统没有连接硬件键盘".我试图为 UIKeyboardImpl 编写一个类别，但我覆盖了:

Erica said that the trick is to answer to the system that "There's no hardware keyboard attached". I tried to write a category for UIKeyboardImpl and I overrided:

- (BOOL)isInHardwareKeyboardMode {
    DEBUG(@"is called");
    return NO;
}   

但直到现在我还没有得到任何东西.调用了被覆盖的方法，但没有软键盘.Erica 还说该应用程序通过动态链接工作，但我不知道如何实现它.我不需要在 AppStore 中，因为这是一个私人应用程序，所以我不用担心被拒绝.

But until now I haven't obtained anything. The overrided method is called but there's no soft keyboard. Erica also said the application works by dynamic linking but I don't know how can I accomplish it. I don't need to be in the AppStore because this is a private application so I don't bother about rejection.

提前致谢

推荐答案

好的.终于得到了.非常感谢大卫、马蒂亚斯和恩里科.以下是步骤:

Ok. Finally got it. Many thanks to David, Matthias and Enrico. Here are the steps:

• 导入私有框架 GraphicsServices
• 在 viewDidLoad 中调用 GSEventSetHardwareKeyboardAttached(NO)

• 添加一个按钮，通过调用来切换键盘

• import the private framework GraphicsServices
• call GSEventSetHardwareKeyboardAttached(NO) inside the viewDidLoad

• add a button that toggles the keyboard by calling

static void toggleKeyboard(UIKeyboardImpl * keyImpl){
if (UIKeyboardAutomaticIsOnScreen()) {
    UIKeyboardOrderOutAutomatic();
} else {
    UIKeyboardOrderInAutomatic();
}

我在 http://code.google.com/p 上找到了这个功能/btstack/wiki/iPhoneKeyboardHiding现在我可以同时从软键盘和蓝牙设​​备接收输入.

I've found this function on http://code.google.com/p/btstack/wiki/iPhoneKeyboardHiding Now I can take input from the soft keyboard and from the bluetooth device at the same time.
