A View between Navigation Controller and CollectionView not working with constraints

[omerfarukyilmaz]

Creating a Navigation Controller, Tab Bar, a UIView, and a Collection View programmatically I get this issue:

I may be doing something wrong myself. I am not very experienced creating views programmatically, so bare with me.

When the collectionview's constraints are set to topLayoutGuide.bottomAnchor, it works amazing. But when does there is any UIView in between, it does not work well.

Screenshot:

Adding to the followers: [] also does not work.

Sorry if the title is not very descriptive. I tried explaining detailed in the post.

Btw, love the library and I'm very grateful for it. 👍

Hi @omerfarukyilmaz Sorry it took me so long to respond. The library is meant to follow and adapt the view for a scrollview, if you want to add a toolbar up top you should use the followers params, passing in your view. Alternatively you can use that view as the collectionview header.

Collectionview header would actually do the trick! Thank you.

And no worries, the library is great so thank you for all your work 👍.

@omerfarukyilmaz Well changing navigationController.followScrollView(collectionView)

To

navigationController.followScrollView(collectionView, delay: 0.0, followers: [fakeView, collectionView])

will resolve the issue. I have tried the same and posting the answer.

@andreamazz Is there any way, we can scroll the green view to top, means hiding same as navigation bar along with navigation bar?
