Speed when scrolling #8

Closed uncleho closed 9 years ago

I find that when I use this code with a bunch of items (like hundreds), scrolling is incredibly slow. Is this a problem with the custom layout?

If you are using the Sticky Headers this could cause you some scrolling slowdown as it has to re-calculate the positions of all items in the collectionView every time it moves. If you aren't using Sticky Headers then the calculations are only done when expected (adding/removing items, or resizing collectionView).

Thanks!
