you can't remove (index >= shitIdx-2) if you have lots of cell will very slow because of cell in the rect of screen

Yep, you can just add frame set when index < shitIdx-2,like add frame calculate

By Instruments,I found the reason of frame drop is not attribute generate(ps. we can cache the attribute object,other than create new attribute object every layout loop),but offscreen-Rendered:

        self.layer.shadowOffset = offset
        self.layer.shadowOpacity = opacity
        self.layer.shadowColor = UIColor.black.withAlphaComponent(0.5).cgColor
