Iglistkit: Help with scroll(to:..)

[folexzz]

New issue checklist

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

General information

• iOS version(s): 9.1-now
• CocoaPods/Carthage version: last
• Xcode version: last
• Devices/Simulators affected:
• Reproducible in the demo project? (Yes/No):

So I have a IGListCollectionView that looks like UIPageViewController (horizontal scroll, paging enabled), I need to show the last cell when app loads. How can I do that?

You state that you're using the "last" (assuming latest) version of IGListKit, but as per the discussion here the IGListCollectionView has been removed in version 3.0!

Regardless IGListCollectionView was just a small wrapper of UICollectionView providing some warnings/errors when you tried to use certain methods.

You should be able to scroll the same way you would if it was just a UICollectionView using the scrollToItem(at: indexPath) method like:

collectionView.scrollToItem(at: IndexPathOfLastItem, at: .centeredHorizontally, animated: false)

Does this help?

Thanks @Sherlouk, one more question, how do I find an IndexPath for last item? I've tried few methods, but nothing has helped me :(

[Sherlouk]

Well that will depend on your exact setup, but you just need to construct an IndexPath based on the size of your collection view.

Assuming you follow IGListKit recommendations and have many sections, then you _could_ do something like this:

IndexPath(item: 0, section: collectionView.numberOfSections)
