This what i have done in my custom Keyboard its working

这是我在定制键盘中所做的工作。

//adding pop up when character is tapped
- (void)addPopupToButton:(UIButton *)button
{


    CGRect frame,frame1;
    if(self.view.frame.size.width == 320)
    {
        //Keyboard is in Portrait
        frame = CGRectMake(0, -25, 28, 43);
        frame1=CGRectMake(0, 0, 28, 43);

    }
    else{
        //Keyboard is in Landscape
        frame = CGRectMake(3, -25, 35, 43);
        frame1=CGRectMake(0, 10, 35, 43);

    }
   //create pop up view
    UIView *popUp=[[UIView alloc]initWithFrame:frame];

    //create a label to add to pop up view
    UILabel *text = [[UILabel alloc] init];

    //set frame for the label and set label title
    [text setFrame:frame1];
    [text setText:button.titleLabel.text];
    text.textAlignment=NSTextAlignmentCenter;
    [text setFont:[UIFont boldSystemFontOfSize:30]];
    text.backgroundColor=[UIColor whiteColor];

    //add label as popup view's subview
    [popUp addSubview:text];

    //add pop up view as button's subview
    [button addSubview:popUp];

}


//remove Pop up view
-(void)endPopUpForButton:(UIButton*)button
{
    if ([button subviews].count > 1)
    {
        [[[button subviews] objectAtIndex:1] removeFromSuperview];
    }
}

From the Apple App Extension Programming guide:

来自苹果应用程序扩展编程指南:

Finally, it is not possible to display key artwork above the top edge of a custom keyboard’s primary view, as the system keyboard does on iPhone when you tap and hold a key in the top row.

最后，不可能在自定义键盘主视图的顶部边缘上显示键艺术品，就像iPhone上的系统键盘一样，当你点击并按住最上面一行的键时。

So it seems like you can't add pop-up outside the keyboard frame, so codelgnitor's answer is the best you can do.

看起来你不能在键盘框架外添加弹出窗口，所以codelgnitor的答案是你能做的最好的。
