Skeletonview: Collection View not showing skeleton for cells

What did you do?

I am trying to show skeleton in collection view , i added an image view and a label to a cell set them both skeletonable and also set the cell to skeletonable and in viewDidLoad called showAnimatedGradientSkeleton() on collectionView.

What did you expect to happen?

I thought it should show the collectionView cells as skeleton.

What happened instead?

but it shows the whole collection view as skeleton and the cells dont appear, basically i just have a gray view with a gradient animation showing up.

Steps to reproduce the behavior

Add a collection view , add a cell to it , add imageview and label to cell set isSkeletonable to true
for all of them. Implement the protocol and then run

SkeletonView Environment

SkeletonView version: 1.2.1
Xcode version: 9.3.1
Swift version: 4.0

Please help me with this, it works on the UItableView if i set the EstimatedRowHeight but since UICollectionView does not have any such property i couldn't resolve it. I also tried the sizeForItem method but it doesnt work also.

wow ! i just wasted a couple of hours for this and a dispatch of 0.1 sec resolved the issue.

Doesn't work for me:

That's how my request to show gradient looks like:

@samsidd Hey I seem to have the same issue as you used to have. I wonder what does it mean by a dispatch of 0.1 sec?

The solution for me was to add in file SkeletonView.swift:
DispatchQueue.main.async after addDummyDataSourceIfNeeded() to fileprivate func recursiveShowSkeleton(withType type: SkeletonType, usingColors colors: [UIColor], animated: Bool, animation: SkeletonLayerAnimation?)
But I still have an issue with blinking content before skeleton appears

Hi, this issue should be solved in latest version (1.3).
You need to prepareSkeleton, you can check this PR (https://github.com/Juanpe/SkeletonView/pull/42)

You can achieve with

collectionView.prepareSkeleton { [weak self] (done) in
                if let visibleCells = self?.collectionView.visibleCells {
                    for cell in visibleCells {
                           cell.contentView.showAnimatedSkeleton()
                    }
                }
            }
