无法移动键盘视图iOS9 swift

Question

我需要实现一个不屑一顾的键盘(向下滑动以解除),就像在iOS上的股票消息应用程序中那样.

我有这个代码来获取键盘视图:

func keyboardWillShowWithNotification(notification:NSNotification) {
    let keyboardView = accessoryView.superview
}  

我连接了tableView的UIPanGestureRecognizer,以检测何时需要开始向下移动键盘.

func handleTableViewPan(gr:UIPanGestureRecognizer) {

   let location = panGestureRecognizer.locationInView(self.view)
   let offset = ... //calculated correctly
   keyboardView.frame.origin.y = originalKeyboardFrame.origin.y + offset
}

这个方法适用于iOS 8,但是在iOS 9中,键盘的位置似乎有点不同,所以我无法移动它.也许有人遇到了同样的问题,可以帮助我.谢谢.

在iOS 9中有一个名为UIRemoteKeyboardWindow的键盘的新窗口,因此当您使用accessoryView.superview时,您将得到错误的视图.

要获得正确的视图,请尝试直接从窗口层次结构中找到它:( objective-c code)

-(UIView*)getKeyboardInputView {
    if([[UIDevice currentDevice].systemVersion floatValue] >= 9.0) {
        for(UIWindow* window in [[UIApplication sharedApplication] windows])
            if([window isKindOfClass:NSClassFromString(@"UIRemoteKeyboardWindow")])
                for(UIView* subView in window.subviews)
                    if([subView isKindOfClass:NSClassFromString(@"UIInputSetHostView")])
                        for(UIView* subsubView in subView.subviews)
                            if([subsubView isKindOfClass:NSClassFromString(@"UIInputSetHostView")])
                                return subsubView;
    } else {
        return accessoryView.superview;
    }
    return nil;
}
