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。
我的结果,
预期结果是,
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 riteshhgupta 在 GitHub 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
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。
