Swift-将数组分配给collectionviewcell中的tableview

Question

[我在构建应用程序时正在学习Swift。无论如何，我试图将4个不同的数组分配给4个不同collectionviewcells中的4个不同tableview。我想知道如何放置：

var fallQuarter : [String] = ["HELLO", "HELLO"]
var winterQuarter : [String] = ["BYE", "BYE", "BYE"]
var springQuarter : [String] = ["HI", "HI"]
var summerQuarter : [String] = ["OKAY", "OKAY"]

这四个数组（例如）到collectionviewcell中的tableview。现在，每个collectionviewcell中的每个tableview似乎都显示这4个数组的所有9个项目。但是，我想将每个数组分配给collectionviewcell中的每个tableview。感谢您的提前帮助。

这里是主要代码：

import UIKit

    class yearOne: UICollectionViewController {

    let customCellIdentifier = "cellID"

    let quarters = [
        customLabel (title: "Fall Quarter"),
        customLabel (title: "Winter Quarter"),
        customLabel (title: "Spring Quarter"),
        customLabel (title: "Summer Quarter")
    ]


    override func viewDidLoad() {
        super.viewDidLoad()

        self.collectionView!.register(quarterCell.self, forCellWithReuseIdentifier: 
        customCellIdentifier)

        navigationItem.title = "Year One"
        navigationController?.navigationBar.prefersLargeTitles = true
        collectionView?.backgroundColor = .lightGray
        //navigationItem.prompt = "Click the + button to add courses, Swipe left on a course 
        to delete."

    }


    override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection 
    section: Int) -> Int {
        // #warning Incomplete implementation, return the number of items
        return quarters.count
    }

    override func collectionView(_ collectionView: UICollectionView, cellForItemAt 
    indexPath:IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: 
        customCellIdentifier, 
        for: indexPath) as! quarterCell
        cell.layer.borderColor = UIColor.black.cgColor
        cell.layer.borderWidth = 1
        cell.layer.cornerRadius = 5
        cell.quarters = self.quarters[indexPath.row]
        return cell
    }

    @objc func buttonAction(sender: UIButton!) {
        let destination = SearchPage()
        navigationController?.pushViewController(destination, animated: true)
    }

}

这里是扩展名：

extension yearOne : UICollectionViewDelegateFlowLayout{

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: 
    UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        let width = (view.frame.width - 30)
        return CGSize(width: width, height: 200)
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: 
    UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return 5
    } 
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: 
    UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
        return 1
    }

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: 
    UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
        UIEdgeInsets(top: 30, left: 10, bottom: 30, right: 10)
    }

}

这里是QuarterCell：

class quarterCell: UICollectionViewCell, UITableViewDelegate, UITableViewDataSource{

    var fallQuarter : [String] = ["HELLO", "HELLO"]
    var winterQuarter : [String] = ["BYE", "BYE", "BYE"]
    var springQuarter : [String] = ["HI", "HI"]
    var summerQuarter : [String] = ["OKAY", "OKAY"]

    let tableView:UITableView = {
        let tableView = UITableView()
        tableView.translatesAutoresizingMaskIntoConstraints = false
        return tableView
    }()

    let cellId = "coursesName"

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        switch section {
        case 0:
            return fallQuarter.count
        case 1:
            return winterQuarter.count
        case 2:
            return springQuarter.count
        case 3:
            return summerQuarter.count
        default:
            return 5
        }
    }

    let sectionsArray: [String] = ["fall", "winter", "spring", "summer"]

    func numberOfSections(in tableView: UITableView) -> Int {
        return sectionsArray.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> 
    UITableViewCell {

            return cell

也许您可以尝试使用多维数组：
