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

问题描述

我真的很疯狂，因为当有一个蓝牙输入设备连接到iPad时，我找不到显示软键盘的方式。我在网上进行了一些搜索，这是结果：

• 一个关于stackoverflow的问题，回答很短 iPad：检测是否有外部键盘


• 应用程序由erica sadun为cydia env开发 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，我覆盖了：

   - （BOOL）isInHardwareKeyboardMode {
 DEBUG（@被称为）; 
 return NO; 
} 
  

但是直到现在我还没有获得任何东西。调用覆盖方法，但没有软键盘。
Erica还说应用程序通过动态链接工作，但我不知道如何完成它。我不需要在AppStore，因为这是一个私人应用程序，所以我不打扰拒绝。

提前感谢

解决方案

好的。终于得到了。非常感谢David，Matthias和Enrico。以下是步骤：

• 导入私人框架GraphicsServices


• 调用GSEventSetHardwareKeyboardAttached viewDidLoad



• 添加一个按钮，通过调用

  切换键盘。
  
  

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

此功能在 http://code.google.com/p/btstack/wiki/iPhoneKeyboard隐藏 $ b上$ b现在我可以从软键盘和蓝牙设​​备同时获取输入。

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:

• a question on stackoverflow with a very short answer iPad: detect if external keyboard is present
• an application developed by erica sadun for the cydia env http://www.tuaw.com/2010/06/02/hacksugar-bringing-back-the-on-screen-keyboard/

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;
}   

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.

Thanks in advance

解决方案

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

• 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();
  }
  

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.
