UICollectionView中的垂直和水平滚动方向

Question

Im stuck with the problem to use both vertical and horizontal scroll direction in a UICollectionView in the same UIViewController.

What I've done so far is first a UICollectionView. In top of the UICollectionView I've got a Collection Reusable View. My solution is to implement an other UICollectionView inside of the reusable view but got errors when running the project.

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'the view returned from -collectionView:viewForSupplementaryElementOfKind:atIndexPath (UICollectionElementKindSectionHeader,<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0}) was not retrieved by calling -dequeueReusableSupplementaryViewOfKind:withReuseIdentifier:forIndexPath: or is nil ((null))

So Im actually handling two different CollectionViews in one UIViewController in the same Delegate and Datasource methods.

It is a better approach to build it with a UITablewView? Than add the collectionviews to different UITableViewCells? Or better to start with an UIScrollView and then add two different UICollectionViews to the scrollview?

Answer 1

AFTabledCollectionView

Refer above sample code

In this sample code. UITableView is there and UITableviewCell contains UICollectionView (With horizontal direction).

Some more detail from above sample code regarding to your problem

Take one 'UITableView' having 2 section. Its first section would have 'UICollectionView' and second section has 'UICollectionView'.
