Skip expand navigation bar, progressing dismiss. I think check the initiated navigation bar height and current navigation bar's height in scrollViewDidScroll.

'This NSLayoutConstraint is being configured with a constant that exceeds internal limits' caused by `let cycleStart = self._isInfinite ? twoDistance*CGFloat(self.collectionView!.calculate.totalCount*100000) : 0` I think multiple so big.
