【问题描述】:
我在 tableview 单元格中使用 collectionview。因此,当单击 collectionview 单元格按钮时,会显示我正在使用协议的 viewcontroller..
tableviewcell 和委托的代码:
protocol CustomCellDelegate: class {
func sharePressed(cell: ProposalTableVIewCell)
}
class ProposalTableVIewCell: UITableViewCell, UICollectionViewDelegate,UICollectionViewDataSource {
@IBOutlet weak var attetchmentsCollectionview: UICollectionView!
var delegate: CustomCellDelegate?
public var bidAttatchment: Array<Get_attachments>?
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return bidAttatchment?.count ?? 0
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "AttatchmentCollectionViewCell", for: indexPath) as! AttatchmentCollectionViewCell
let attatchBid = bidAttatchment?[indexPath.item]
cell.attatchmentLbl.text = attatchBid?.filename
cell.openBtn.tag = indexPath.item
cell.openBtn.addTarget(self, action: #selector(connected(sender:)), for: .touchUpInside)
return cell
}
@objc func connected(sender: UIButton){
delegate?.sharePressed(cell: self)
}
viewcontroller 的代码:当我按下sharePressed 时,只获取collectionview 的第一个单元格值..如何获取所有单元格值..请告诉我
class ViewMyAppliedReqVC: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate, CustomCellDelegate{
func sharePressed(cell: ProposalTableVIewCell) {
guard let index = tableView.indexPath(for: cell)?.row else { return }
let name = getBitDetails?.result?.bid?.get_attachments?[index].filename// always getting only first cell value
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ViewProposalTableVIewCell1", for: indexPath) as! ViewProposalTableVIewCell1
cell.bidAttatchment = getBitDetails?.result?.bid?.get_attachments
cell.delegate = self
cell.attetchmentsCollectionview.reloadData()
return cell
}
