Header Section animating while using reloadSections

have requirement in which I have to reload particular section instead of whole collectionView.
Now when I scroll collectionView and then try to reload that section, the header section comes with top to down animation. Can you pls help me ?

[CollectionView reloadSections:[NSIndexSet indexSetWithIndex:sender.tag]]

crash on iOS 10 when reloadData

layout attributes for supplementary item at index path (<NSIndexPath: 0xc000000000000116> {length = 2, path = 1 - 0}) changed from <UICollectionViewLayoutAttributes: 0x6100001fdf00> index path: (<NSIndexPath: 0xc000000000000116> {length = 2, path = 1 - 0}); element kind: (UICollectionElementKindSectionHeader)

Section Headers behave incorrectly with bottom insets

PDKTStickySectionHeadersCollectionViewLayout is not taking into account the bottom inset of the section and it starts to scroll up before time. Pinned to the last cell

Find out if header stuck to top

Hi. Is there a way to find out when a header became sticky?
I would like to add a drop shadow to the header when it becomes sticky.

Thanks

Ability to disable stick to top behaviour for a given section

I would be convenient to disable the stick to top behaviour for a specific section. A delegate method to ask the if a section should stick to top would be great.
