如何隐藏键盘助手栏(How to hide the keyboard assistant bar)

 我正在使用iPad应用程序，我无法隐藏UIKeyboardAssistantBar ，软键盘上方显示的条形图，带有文本预测等。请参见下图，其中显示了全键盘， UIKeyboardAssistantBar参考 - 条形图I想隐藏在键盘上方（显示“2”的那个） 
 
  
 
 我遇到的问题是当使用外部键盘时：当文本视图获得焦点时，软键盘不会显示，但是总是显示助手栏 - 到目前为止我找到的唯一方法是让用户手动使用最右侧的图标隐藏它。 
 
 理想情况下，我正在寻找的解决方案是一个全局调用，启用或禁用它，这样我就不必为每个文本视图单独处理它。 
 
 任何想法？ 

I'm working on an iPad app, and I am unable to hide the UIKeyboardAssistantBar, the bar shown above the soft keyboard, with text prediction etc. See picture below, which shows the full keyboard, just to give a reference - the bar I want to hide is above the keyboard (the one displaying "2")
 
 
The problem I have is when an external keyboard is used: the soft keyboard is not shown when a text view obtains the focus, but that assistant bar is always shown instead - the only way I've found so far is to let the user manually hide it, using the icon at the far right.
 
Ideally, the solution I'm looking for is a global call that enables or disables that, so that I don't have to handle that individually for each text view.
 
Any idea?
