<p>我的完整 ViewController 代码是,</p>
<pre><code>import UIKit
class ReviewVC: UIViewController , UICollectionViewDataSource , UICollectionViewDelegate , UICollectionViewDelegateFlowLayout{
var cellWidthArr : =
var titleArr = ["Polite" , "Showed up on time", "Quick responses" , "Fair prices"]
override func viewDidLoad() {
super.viewDidLoad()
self.navigationItem.title = "Review your experiance"
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 0
collectionView!.collectionViewLayout = layout
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 4
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "ReviewCollectionCell", for: indexPath)as? ReviewCollectionCell
cell?.titleLabel.text = self.titleArr
cell?.titleLabel.layer.cornerRadius = (cell?.titleLabel.bounds.size.height)!/2
cell?.titleLabel.clipsToBounds = true
cell?.titleLabel.layer.borderColor = (UIColor.init(red: 240/255, green: 36/255, blue: 70/255, alpha: 1.0)).cgColor
cell?.titleLabel.layer.borderWidth = 1.0
return cell!
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
return UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize
{
return CGSize(width: self.cellWidthArr, height: 30)
}
}

<p><p>您可以使用开源项目<a href="https://github.com/riteshhgupta/TagCellLayout" rel="noreferrer noopener nofollow">TagCellLayout</a> <strong>riteshhgupta</strong> 在 <code>GitHub</code> 中编写。</p>
<p>初始化布局的示例代码:</p>
<pre><code>import TagCellLayout
let tagCellLayout = TagCellLayout(alignment: .left, delegate: self)
collectionView.collectionViewLayout = tagCellLayout
</code></pre>
