Iglistkit: How to get the contentOffset value from IGListCollectionView?

[HumidBrains]

New issue checklist

• [x] I have reviewed the README and documentation
• [x] I have searched existing issues and this is not a duplicate

General information

• IGListKit version: 2.1.0
• iOS version(s): 10.2
• CocoaPods/Carthage version: 1.2.0.beta.3
• Xcode version: 8.2 beta
• Devices/Simulators affected:
• Reproducible in the demo project? (No):
• Related issues: #158

For UICollectionView we can get e.g. collectionView.contentOffset.y value from scrollViewDidScroll(_ scrollView: UIScrollView), but is there any way to get a content offset value when using IGListCollectionView?

I need it in order to manipulate constraints and/or view positions on other views based on scroll.
Any help is much appreciated.

I started asking in #158 due to its relevance, but as it's closed I created a new issue. Hope that's okay.

@HumidBrains i think you can still receive UIScrollViewDelegate callbacks if you specify an object for the scrollViewDelegate property on your list adapter.

Thanks @jamieQ, this was embarrassingly simple :)

For others who are as confused as I am, just make sure the adapter is your scrollview delegate by adding adapter.scrollViewDelegate = self and you're good to go.

So then you can do e.g.
func scrollViewDidScroll(_ scrollView: UIScrollView) { print(collectionView.contentOffset.y) }
