SkeletonView Environment:

SkeletonView version: 1.16.0 Xcode version: Version 12.5 (12E262) **Swift version: 5.0

Steps to reproduce:

Please replace this with the steps to reproduce the behavior.

1. Create a UICollectionView with a layout of UICollectionViewFlowLayout ( vertical )
2. Set the skeletonable properties in a UICollectionViewCell
3. Set the contentOffset to (top: 180, left: 25, bottom: 80, right: 20)
4. Use showSkeleton, and then Hideskeleton after making/mocking a network request

Expected result:

Please replace this with what you expected to happen. It was supposed to just stay in place and show the skeleton animation.

Actual result:

Please replace this with of what happened instead.
However, I'm getting a weird result. The collectionView is shifted upwards by about 30-40 points, and then once skeleton is stopped it moves back to the intended position. It's as if skeletonView is overriding the contentOffset value that I originally set.

I couldn't reproduce the problem with a CollectionView (I think you mean contentInset when you say contentOffset), but I recently had the same problem with a TableView and fixed it by setting isScrollEnabled = true on the TableView immediately after calling the showSkeleton method.

@harrisonsj, I actually tried that, and yes I did mean contentInset. However, it doesn't seem to work with UICollectionView. It's a really annoying bug, but the temporary solution right now for me is to change the contentInset manually.

[az0r234]

I figured out a better solution. I believe every-time that the showSkeleton method is being called, it readjusts the contentInset for UICollectionView, and with that also readjusts the content area of the scrollview. To fix it, what I did was set the contentAdjustmentBehavior for collectionView to .never: collectionView.contentAdjustmentBehavior = .never
