showsInfiniteScrolling = NO causes jump stutter on UICollectionView

[strivingboy]

I found this animation effect:

• (void)setScrollViewContentInset:(UIEdgeInsets)contentInset {
  [UIView animateWithDuration:0.3
  delay:0
  options:UIViewAnimationOptionAllowUserInteraction|UIViewAnimationOptionBeginFromCurrentState
  animations:^{
  self.scrollView.contentInset = contentInset;
  }
  completion:NULL];
  }
