uicollectionreusableview

I'm trying to make a detail screen for a to-do list kind of app. Here's what the detail screen currently looks like: This is a UICollectionViewController , with a header.

I have two sections in UICollectionView . I want to show a section header in UICollectionView for only 1st section. Not in 0th section. So I tried to return nil in viewForSupplementaryElementOfKind : method for section == 0 and returns view for the section == 1 . It crashes and shows below error: Assertion failure in -[UICollectionView _createPreparedSupplementaryViewForElementOfKind:atIndexPath:withLayoutAttributes:applyAttributes]: Here it is my code for the supplementary view. - (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:

I have a UICollectionView . I would like to add a header. My header would only be a UILabel . I've : 1) selected "Section Header" as a Collection View accessory in the IB. 2) created a Collection Reusable View in the IB, on the side, declared as collectionViewHeader . 3) added those lines : - (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath { if (kind == UICollectionElementKindSectionHeader) { return collectionViewHeader; } return nil; } But they are never called.
