collectionView.collectionViewLayout = tagsFlowLayout
// register cell
collectionView.register(nib: UINib(nibName: "ExampleCell", bundle: nil), forCellWithReuseIdentifier: "ExampleCell")
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "ExampleCell", for: indexPath) as! ExampleCell
cell.maxWidth = collectionView.bounds.width - 30
return cell
}
}
class TagCollectionViewCell: UICollectionViewCell {
@IBOutlet weak var tagLabel: UILabel!
@IBOutlet private var maxWidthConstraint: NSLayoutConstraint! {
