CollectionView sizeForItemAtIndexPath never called

Question

This is driving me crazy! I have a UICollectionViewController as shown below:

class PhrasesCompactCollectionViewController: UICollectionViewController
         


        

Answer 1

In Swift 3+ Use this method:

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    return CGSize(width:(collectionView.frame.height-90)/2, height: 100)
}

Make sure that your class complies both Delegate

• UICollectionViewDelegate

• UICollectionViewDelegateFlowLayout
