如何快速将字符放入单独的collectionViewCell中

Question

enter image description here我做单词游戏，我有一个单词，这个单词需要分成多个字符，每个字符都应添加到一个单独的单元格中，并且单词之间要留有空格，同时使用自定义类标签。为此，我使用了集合视单元，我无法向每个单元中添加字符，只能将整个单词传输到每个单元中。请帮助解决此问题。

P.S，我按原样添加了屏幕截图enter image description here

我的代码

ViewController.swift

import UIKit

class ViewController: UIViewController {

    let cellID = "Cell"
    let word = "Hello My People"
    var index = 0
    var targets = [TargetView]()

    lazy var collectionView: UICollectionView = {
        let layout = UICollectionViewFlowLayout()
        layout.minimumLineSpacing = 12
        layout.minimumInteritemSpacing = 3
        let collectionView1 = UICollectionView(frame: .zero, collectionViewLayout: layout)
        collectionView1.backgroundColor = .red
        collectionView1.translatesAutoresizingMaskIntoConstraints = false
        return collectionView1

    }()

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .brown
        view.addSubview(collectionView)
        collectionView.dataSource = self
        collectionView.delegate = self
        collectionView.register(CharCell.self, forCellWithReuseIdentifier: cellID)

        collectionView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 16).isActive = true
        collectionView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -16).isActive = true
        collectionView.topAnchor.constraint(equalTo: view.topAnchor, constant: 400).isActive = true

        //var anagram1 = word.count



    }


}

问题是您在每个单元格中都将cell.label.text设置为word。只需将短语拆分为组件并将其添加到数组即可。在我的示例中，我对其进行了简化。
