ios - 将单元格添加到 Collection View 。 swift

Question

我通过 xib 创建了一个 View 集合和一个自定义单元格。

单元格上只有一个Label。

我必须通过 TextField 输入文本，用该文本填充数组，然后将其放入单元格中。

我需要在 TextField 中的每个文本条目之后创建一个单元格。

我还没有接触过集合，也不太明白它是如何工作的。

这就是我的全部

CollectionCell.swift:

import UIKit
class CollectionPlayersCell: UICollectionViewCell {

    @IBOutlet weak var playerCell: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
     //someCode
    }

}

ViewController.swift

import UIKit

class ViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet weak var collectionPlayersView: UICollectionView!
    @IBOutlet weak var nameTextFIeld: UITextField!
    let playerCellId = "playersCell"
    var playersNames = [String]()

    @IBAction func inputNameField(_ sender: UITextField) {

        playersNames.append(nameTextFIeld.text!)

    }
    override func viewDidLoad() {
        super.viewDidLoad()

        let nibPlayersCell = UINib(nibName: playerCellId, bundle: nil)
        colecctionPlayersView.register(nibPlayersCell, forCellWithReuseIdentifier: playerCellId)
        notificationKeyboard()

    }


extension ViewController: UICollectionViewDelegate, UICollectionViewDelegateFlowLayout, UICollectionViewDataSource
{
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: playerCellId, for: indexPath) as! CollectionPlayersCell
        cell.playerCell.text = playersNames[indexPath.row]
        return cell
    }

    func numberOfSections(in collectionView: UICollectionView) -> Int {
        return 1
    }

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


}

您需要提及您的 xib 文件名而不是“playerCellId”

let nibPlayersCell = UINib(nibName: playerCellId, bundle: nil)

需要 nibName = "YourNibName"

如果你的 nib 名称是 CollectionPlayersCell，那么这应该是这样的 -

let nibPlayersCell = UINib(nibName: "CollectionPlayersCell", bundle: nil)
