标题: ios - 更改 UICollectionView 单元格 X 位置 - 快速

如何以编程方式更改每个单元格的 X 位置?我可以根据需要更改单元格的宽度和高度,但由于 XY 位置,无法完成项目。

enter image description here

我的完整 View Controller 代码是,

import UIKit

class ReviewVC: UIViewController , UICollectionViewDataSource , UICollectionViewDelegate , UICollectionViewDelegateFlowLayout{


    var cellWidthArr : [CGFloat] = [60.0 , 170.0 , 110.0 , 120.0]


    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[indexPath.row]

        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[indexPath.row], height: 30)
    }
}

任何人请帮我找出解决方案。谢谢...

您可以使用开源项目TagCellLayout riteshhguptaGitHub 中编写。

初始化布局的示例代码:

import TagCellLayout

let tagCellLayout = TagCellLayout(alignment: .left, delegate: self)
collectionView.collectionViewLayout = tagCellLayout

enter image description here

我知道您可能会为此编写大量代码,但这会很有帮助,甚至您可以自定义不同的布局对齐方式。
