是否可以在单元格外显示 tableViewCell 的标签?即,默认情况下,标签出现在函数
中func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell2 = tableView.dequeueReusableCell(withIdentifier: "cell2", for: indexPath) as! DetailTableViewCell2
cell2.currentPageNumber.text = "1/\(Images?.Photo.count ?? 0)"
return cell2
我想在此函数中显示currentPageNumber.text
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
let pageNumber = round(scrollView.contentOffset.x / scrollView.frame.size.width)
currentPageNumber?.text = "\(String(Int(pageNumber) + 1))/\(Images?.Photo.count)"
}
tableViewCell :
class DetailTableViewCell2: UITableViewCell {
@IBOutlet weak var currentPageNumber: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
currentPageNumber.layer.zPosition = 2
currentPageNumber.layer.cornerRadius = 15.0
currentPageNumber.clipsToBounds = true
}
}
有可能吗?如果可能的话,怎么样?

这里有可见的单元格IndexPath
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
//replace your cell class and tableView Object
for cell in tableView.visibleCells {
let indexPath: IndexPath? = tableView.indexPath(for: cell)
print("\(indexPath)")
}
}

这对我很有帮助
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
let indexPath = IndexPath(row: 0, section: 0)
if let cell = tableView.cellForRow(at: indexPath) as? DetailTableViewCell2 {
let pageNumber = round(scrollView.contentOffset.x / scrollView.frame.size.width)
cell.currentPageNumber.text = "\(String(Int(pageNumber) + 1))/\(hallImages?.ImagesHalls.count ?? 0)"
}
}
