通过该特定单元格中的按钮删除tableviewcell

问题描述

我下面的代码使用tableVIEWVIEW单元格显示单个按钮。我想做的是在tableVIEWVIEW单元格中具有名为deleteBTN的按钮，删除该指定的tableview单元格，仅删除该单元格。我不知道应该将删除放入哪个类。这可能使用委托从该特定单元中删除。

import UIKit

class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource,UIImagePickerControllerDelegate,UINavigationControllerDelegate {

    var numberOfRows = 3

    func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int { numberOfRows }

    func tableView(_ tableView: UITableView,heightForRowAt indexPath: IndexPath) -> CGFloat { 118 }

    var tableView = UITableView()
    var selectedIndexPath = IndexPath(row: 0,section: 0)

    override func viewDidLoad() {
        super.viewDidLoad()

        setTableVIew()
    }
    

    func setTableVIew(){
    
             view.addSubview(box2)
         
             box2.backgroundColor = .systemTeal
             
             
    
       
        
        let VCframe = view.frame
        let height = VCframe.height * 0.8
            let height2 = VCframe.height * 0.2
        let widthx = VCframe.width

        
        
             tableView.frame = CGRect(x: 10,y: 0,width: widthx - 20,height: height)
          
        tableView.delegate = self
        tableView.dataSource = self
        view.addSubview(tableView)
        tableView.backgroundColor = .blue
        box2.addTarget(self,action: #selector(lease),for: .touchDown)

        tableView.register(customtv.self,forCellReuseIdentifier: "cell")
    }
    

    func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell",for: indexPath) as! customtv
        cell.textLabel?.text = "\(indexPath.row)"
        cell.press.tag = indexPath.row
        cell.press.addTarget(self,action: #selector(importPhoto),for: .touchDown)
        return cell
    }

 
}
class customtv: UITableViewCell {
    lazy var backView : UIView = {
      let view = UIView(frame: CGRect(x: 10,y: 6,width: self.frame.width,height: 110))
      view.backgroundColor = .green
      print(self.frame.width)
          return view
      }()
      

      
      override func layoutSubviews() {
         backView.clipsToBounds = true
         backView.frame =  CGRect(x: 0,width: bounds.maxX,height: 110)
   

      }


    lazy var deleteBTN : UIButton = {
        let press = UIButton(frame: CGRect(x: 300,y: 3,width: 65,height: 50))
        press.backgroundColor = .systemBlue
        press.setTitle("DELETE",for: .normal

        return press
    }()

 

    override func setSelected(_ selected: Bool,animated: Bool) {
        super.setSelected(animated,animated: true)
        addSubview(backView)
        backView.addSubview(deleteBTN)
    }
}

解决方法

您可以添加与添加目标按钮相同的内容

func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell",for: indexPath) as! customtv
        cell.textLabel?.text = "\(indexPath.row)"
        cell.press.tag = indexPath.row
        cell.press.addTarget(self,action: #selector(importPhoto),for: .touchDown)
        cell.deleteBTN.addTarget(self,action: #selector(deleteCell),for: .touchUpInside)
        return cell
    }
