Question on the Calendar view

[roro95]

Hi

Thanks for this project which is very useful. However I would have a question regarding the handling of the vertical "Hour " as I don't undestand where it is managed . I tried to chnage the number of hours per day with no effect. From where it is dequeued ?
Hope it's clear :)
extension CalendarViewController: SapporoDelegate {
func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView {
if kind == CalendarHeaderType.Day.rawValue {
let view = collectionView.dequeueReusableSupplementaryViewOfKind(kind, withReuseIdentifier: CalendarHeaderView.reuseIdentifier, forIndexPath: indexPath) as! CalendarHeaderView
view.titleLabel.text = "Day (indexPath.item + 1)"
return view
}

**    let view = collectionView.dequeueReusableSupplementaryViewOfKind(kind, withReuseIdentifier: CalendarHeaderView.reuseIdentifier, forIndexPath: indexPath) as! CalendarHeaderView
    view.titleLabel.text = "Hour \(indexPath.item + 1)"
    return view**
