How to hide the shortcut bar in iOS9

I have a textfield with a hidden keyboard (since I'm using it with bluetooth). However, in iOS9 the shortcut bar keeps appearing.

Is there a way to hide it too?

Thank you so much!

You can pass your textfield name in place of userNameTextField for which you want to remove shortcut bar.

UITextInputAssistantItem* item = [userNameTextField inputAssistantItem];
item.leadingBarButtonGroups = @[];
item.trailingBarButtonGroups = @[];

In Swift 2.0

if #available(iOS 9.0, *) {
    let item : UITextInputAssistantItem = yourTextView.inputAssistantItem
    item.leadingBarButtonGroups = []
    item.trailingBarButtonGroups = []
} else {
  // Fallback on earlier versions
}
