我已经设置了一个集合视图，该视图水平滚动并显示“companies”数组中的元素。

单元格根据标签宽度自动调整大小。

我使用了下面的代码和故事板约束来实现这个目标：

class addTextStatus: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource {

    var companies: [String] = ["Everyone","Limited", "Friends", "Only Me", "Test Length Cells", ]

    @IBOutlet weak var collectionView: UICollectionView!
    @IBOutlet weak var userImage: UIImageView!
    override func viewDidLoad(){

              collectionView.register(UINib.init(nibName: "statusCompanyCollectionView", bundle: nil), forCellWithReuseIdentifier: "cell4")

        if let flowLayout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout {
            flowLayout.estimatedItemSize = CGSize(width: 1,height: 1)

        }

        userImage.layer.masksToBounds = false
        userImage.layer.cornerRadius = userImage.frame.height/2
        userImage.clipsToBounds = true
    }
    @IBOutlet weak var backButton: UIButton!
    @IBAction func backButton(_ sender: Any) {

       dismiss(animated: true, completion: nil)

    }

    override var preferredStatusBarStyle : UIStatusBarStyle {
        return UIStatusBarStyle.default  
    }

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return self.companies.count
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {


        let cell4 = collectionView.dequeueReusableCell(withReuseIdentifier: "cell4", for: indexPath) as! statusCompanyCollectionView

        cell4.company.text = self.companies[indexPath.item]

        return cell4
    }

    }
