UICollectionView and Supplementary View (header)

Question

Trying to add a a Supplementary view into my UICollectionView as a header. I\'m having issues getting it to work.

I use a custom UICollectionViewFlowL

Answer 1

I was having the same issue and similarly, I was not registering the header correctly. there are several threads on here that all suggest using a Nib to define the header but I have done it differently and is working fine.

I have a custom header SizeCollectionHeader, which inherits the UICollectionReusableView. It is registered like this.

    [self.collectionView registerClass:[GRSizeCollectionHeader class] forSupplementaryViewOfKind:@"UICollectionElementKindSectionHeader"
                                                                             withReuseIdentifier:@"SupplementaryViewIdentifier"];

and is working fine.

my initial problem was that had a random "Kind" value like this.

    [self.collectionView registerClass:[GRSizeCollectionHeader class] forSupplementaryViewOfKind:@"SupplementaryViewKind"
                                                                             withReuseIdentifier:@"SupplementaryViewIdentifier"];

This will crash.

So I just wanted to comment for anybody that is looking here that you don't need to use a nib.
