viewForSupplementaryElementOfKind and referenceSizeForFooterInSection not called?

[tnahvu]

Hi

First, thanks for the awesome library! I'm not quite sure how to properly implement footer/header view. Does the normal way not work? Is there something else I need to do ? viewForSupplementaryElementOfKind and referenceSizeForFooterInSection not called when using CHTCollectionViewWaterfallLayout.

Again, many thanks!

1. viewForSupplementaryElementOfKind will get called, you can see the demo for more information.
2. referenceSizeForFooterInSection will NOT get called, because it belongs to UICollectionViewDelegateFlowLayout but my CHTCollectionViewDelegateWaterfallLayout confirms to UICollectionViewDelegate.

@chiahsien I get a crash in viewForSupplementaryElementOfKind when dequeueReusableSupplementaryViewOfKind:reuseIdentifier is called. This is the info i have about the crash...

Assertion failure in -[UICollectionViewData layoutAttributesForSupplementaryElementOfKind:atIndexPath:]

I'm setting the footer height property of the layout like you say to do. What am i missing here? By the way I am changing between this layout and another layout which shows my cells in a tableview style layout, and when I am in that layout my footer view shows up just fine.

@Gman9855 Have you figured out the problem, cuz I'm facing exactly the same problem.

[Gman9855]

@cheriaa I've gotten it to at least not crash now. You have to register the UICollectionReusableView class first. So now what I have is the extra space I provided to the layout's footerHeight property, but the supplementary view doesn't appear, even though viewForSupplementaryElementOfKind gets called.

hi,'ve got a same problem. when i make a UICollectionViewFlowLayout's subclass,and registered that into collectionView.But the method "viewForSupplementaryElementOfKind" could not be called.Contrarily, i had done this like [[UICollectionView alloc] initWithFrame:CGRectZero collectionViewLayout:_layout],that method will be called. Could you get my mind and help me to solve it? Thanks
