你想要的我都有

首先创建一个继承于UITableViewController的类
var sectionName:[String] = []
var rowName1:[String] = []
var rowName2:[String] = []
var rowName3:[String] = []
var rowName4:[String] = []
var cellNum:Int = 0
剩下的就是代码上面的定义的东西
override func viewDidLoad() {
super.viewDidLoad()
self.navigationItem.title = “啦啦啦”

    sectionName = ["1","2","3","4"]
    
    self.tableView.delegate = self
    self.tableView.dataSource = self
    
    self.tableView.tableFooterView = UIView()
    
    self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "全部", style: .plain, target: self, action: #selector(whole))
}
@objc func whole() {
    
    if rowName1.count>0{
        print("1：\(rowName1[0]),\(rowName1[1]),\(rowName1[2])")
    }
    if rowName2.count>0{
        print("2：\(rowName2[0]),\(rowName2[1]),\(rowName2[2])")
    }
    if rowName3.count>0{
        print("3：\(rowName3[0]),\(rowName3[1]),\(rowName3[2])")
    }
    if rowName4.count>0{
        print("4：\(rowName4[0]),\(rowName4[1]),\(rowName4[2])")
    }
    
    
}

// MARK: - Table view data source

override func numberOfSections(in tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return sectionName.count
}

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    switch section {
    case 0:
        return rowName1.count
    case 1:
        return rowName2.count
    case 2:
        return rowName3.count
    case 3:
        return rowName4.count
    default:
        return 0
    }
}


override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    var cell:UITableViewCell! = tableView.dequeueReusableCell(withIdentifier: "cell")
    if cell==nil{
        
        cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
    }
    // Configure the cell...
    
    switch indexPath.section {
    case 0:
        cell.textLabel?.text = rowName1[indexPath.row]
    case 1:
        cell.textLabel?.text = rowName2[indexPath.row]
    case 2:
        cell.textLabel?.text = rowName3[indexPath.row]
    case 3:
        cell.textLabel?.text = rowName4[indexPath.row]
    default:
        ""
    }
    
    return cell!
}

//    override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
//
//        return sectionName[section]
//    }

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    
    return 80
    
}


override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    
    let view = UIView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
    view.backgroundColor = UIColor.lightGray
    
    let btn = UIButton(frame: CGRect(x:UIScreen.main.bounds.width-80-10, y: 10, width: 80, height: 30))
    btn.setTitle("录入分数", for: .normal)
    btn.addTarget(self, action: #selector(buton), for: .touchUpInside)
    btn.setTitleColor(UIColor.red, for: .normal)
    view.addSubview(btn)
    btn.tag = 100+section
    
    let label = UILabel(frame: CGRect(x: 10, y: 10, width: 60, height: 30))
    view.addSubview(label)
    label.text = sectionName[section]
    
    let lineView = UIView(frame: CGRect(x: 0, y: 49, width: UIScreen.main.bounds.width, height: 1))
    view.addSubview(lineView)
    lineView.backgroundColor = UIColor.black
    return view
}

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    
    return 50
}

@objc func buton(but:UIButton){
    
    print(but.tag)
    
    let vc = EnteringGradeViewController()
    vc.jumpScore = {
        
        (str1,str2,str3)->() in
        
        switch but.tag {
        case 100:
            self.rowName1.removeAll()
            self.rowName1.append("语文：\(str1)")
            self.rowName1.append("数学：\(str2)")
            self.rowName1.append("英语：\(str3)")
        case 101:
            self.rowName2.removeAll()
            self.rowName2.append("语文：\(str1)")
            self.rowName2.append("数学：\(str2)")
            self.rowName2.append("英语：\(str3)")
        case 102:
            self.rowName3.removeAll()
            self.rowName3.append("语文：\(str1)")
            self.rowName3.append("数学：\(str2)")
            self.rowName3.append("英语：\(str3)")
        case 103:

            self.rowName3.append("语文：\(str1)")
            self.rowName3.append("数学：\(str2)")
            self.rowName3.append("英语：\(str3)")
        default:
            ""
        }
        self.tableView.reloadData()
    }
    self.navigationController?.pushViewController(vc, animated: true)
}
}
创建一个继承于UIviewcontrol的类
typealias blockScore = (String,String,String)->()
var jumpScore:blockScore?

var tf1:UITextField!
var tf2:UITextField!
var tf3:UITextField!

override func viewDidLoad() {
    super.viewDidLoad()

    let lab3 = UILabel(frame: CGRect(x: 30, y: 200+lab1.frame.height+10+lab2.frame.height+10, width:60 , height: 60))
    view.addSubview(lab3)
    lab3.text = "英语"
    
    tf1 = UITextField(frame: CGRect(x: 50+lab1.frame.width+5, y: 200, width: UIScreen.main.bounds.width-(50+lab1.frame.width+5)-10, height: 60))
    view.addSubview(tf1)
    tf1.placeholder = "请输入分数"
    tf1.borderStyle = .roundedRect

    view.addSubview(tf3)

    tf3.borderStyle = .roundedRect
    
    let btn1 = UIButton(frame: CGRect(x: (UIScreen.main.bounds.width-100)/2-60, y: 200+lab1.frame.height+10+lab2.frame.height+10+lab3.frame.height+30, width: 100, height: 80))
    view.addSubview(btn1)
    btn1.setTitle("保存", for: .normal)
    btn1.addTarget(self, action: #selector(save), for: .touchUpInside)
    btn1.setTitleColor(UIColor.red, for: .normal)
    
    let btn2 = UIButton(frame: CGRect(x: (UIScreen.main.bounds.width-100)/2+60, y: 200+lab1.frame.height+10+lab2.frame.height+10+lab3.frame.height+30, width: 100, height: 80))
    view.addSubview(btn2)
    btn2.setTitle("返回", for: .normal)
    btn2.addTarget(self, action: #selector(back), for: .touchUpInside)
    btn2.setTitleColor(UIColor.red, for: .normal)
}

@objc func save() {
    
    self.jumpScore!(tf1.text!,tf2.text!,tf3.text!)
    
    self.navigationController?.popViewController(animated: true)
