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,但是由于XY位置而无法完成项目。
我的全视图控制器代码是
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)
}
}
任何人都可以帮助我找出解决方案。谢谢...

您可以使用 riteshhgupta 在function listUsersInSwal(merchantId){
var usersList = ['user1','user2','user3'];
swal({
title: "Message ",
text: "Enter Message:",
showCancelButton: true,
closeOnConfirm: false,
animation: "slide-from-top",
input: 'select',
inputOptions: usersList
})}
中编写的开源项目TagCellLayout。
用于初始化布局的示例代码:

我知道您可能为此编写了很多代码,但这将非常有帮助,甚至您可以自定义不同的布局对齐方式。

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return (ArrayName[indexPath.row] as NSString).size(withAttributes: nil)
}
除了在数组中提供单元格固定大小外,还有一种方法可以在sizeForItemAtIndexPath中查找标签大小,以返回文本的大小,这样它将找到大小并起作用
