I have a tableView and in every tableViewCell is a collectionView.
I am trying to change the collectionView size with this code:
func collectionView(_ collectionView: UICollectionView,
layout collectionViewLayout: UICollectionViewLayout,
sizeForItemAt indexPath: IndexPath) -> CGSize {
if collectionView.tag == 2{
return CGSize(width: 100, height: 100)
}else if collectionView.tag == 4 {
return CGSize(width: 222, height: 200)
}else{
return CGSize(width: 10, height: 10)
}
}
The problem is that there is no error but cells do not change sizes
If you need to know something more, just write a comment.
Thank you.
So This is my code right now and it works:
collectionView.delegate = dataSourceDelegate
collectionView.dataSource = dataSourceDelegate
collectionView.tag = row
collectionView.setContentOffset(collectionView.contentOffset, animated:false)
collectionView.reloadData()
collectionView.register(UINib(nibName: "eventsCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "eventsCollectionViewCell")
if row == 2{
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
layout.itemSize = CGSize(width: 120, height: 120)
layout.scrollDirection = .horizontal
collectionView.collectionViewLayout = layout
}else if row == 4 {
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
layout.itemSize = CGSize(width: 222, height: 200)
layout.scrollDirection = .horizontal
collectionView.collectionViewLayout = layout
}else{
print("else")
}
