Swift iOS - Tag collection view

Question

I'm writing my first iOS app and I wanna just answer what is the best-known solution to make this? It's simple tag collection. I have already looked over the Internet but I have found nothing. I think the best way is to make my own structure of buttons maybe?

Here is what I want to achieve:

Answer 1

I resolve this problem, using collection view.

class FilterController: UIViewController, UICollectionViewDelegateFlowLayout, UICollectionViewDataSource {

    @IBOutlet var collectionView: UICollectionView?


    override func viewDidLoad() {
    super.viewDidLoad()


    // Do any additional setup after loading the view, typically from a nib.
    let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    layout.sectionInset = UIEdgeInsets(top: 150, left: 10, bottom: 150, right: 10)
    // layout.itemSize = CGSize(width: 90, height: 45)
    layout.itemSize = CGSizeFromString("Aloha")

    collectionView = UICollectionView(frame: self.view.frame, collectionViewLayout: layout)
    collectionView!.dataSource = self
    collectionView!.delegate = self
    collectionView!.registerClass(TagCell.self, forCellWithReuseIdentifier: "TagCell")
    collectionView!.backgroundColor = UIColor.whiteColor()

    self.view.addSubview(collectionView!)
}
