Question

I’m subclassing UICollectionViewController.

UITableView header repeats after every row of cells that i have.
I need the header to be “single” and always on the top of the screen (like the navigation bar).

I’m using the following code:
my UICollectionViewController class:

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
    return [categoryArray count] / 2;
}

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
    return 2;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    CategoryCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"CategoryCell" forIndexPath:indexPath];
    CategoryViewModel *category = [categoryArray objectAtIndex:(indexPath.section*2 + indexPath.row)];
    cell.name.text = category.name;
    cell.image.image = category.image;
    return cell;
}

-(UICollectionReusableView *) collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath{
    if(headerIndexPath == nil){
        headerIndexPath = indexPath;
    }
    CategoryScreenHeader *categoryScreenHeader = [collectionView dequeueReusableSupplementaryViewOfKind:
                                         UICollectionElementKindSectionHeader withReuseIdentifier:@"CategoryScreenHeader" forIndexPath:headerIndexPath];
    categoryScreenHeader.headerName.text = @"Some title";
    categoryScreenHeader.headerImage.image = [UIImage imageNamed:@"step-0.png"];
    return categoryScreenHeader;
}

Thank you.
