Я учу Swift при создании приложения. В любом случае, я пытаюсь назначить 4 разных массива в 4 разных табличных представления в 4 разных коллекционных ячейках. Мне было интересно, как я смогу поместить:
var fallQuarter : [String] = ["HELLO", "HELLO"]
var winterQuarter : [String] = ["BYE", "BYE", "BYE"]
var springQuarter : [String] = ["HI", "HI"]
var summerQuarter : [String] = ["OKAY", "OKAY"]
эти четыре массива (например) в табличное представление в collectionviewcell. Прямо сейчас каждый вид таблицы в каждой ячейке коллекции, кажется, отображает все 9 элементов этих 4 массивов. Тем не менее, я хочу назначить каждый массив для каждого табличного представления в элементе collectionview. Заранее спасибо за помощь.
Вот основной код:
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)
}
}
Вот расширение:
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)
}
}
Вот четверть ячейки:

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

}
}
