【ios开发/Xcode】使用UITableView完成学生信息及成绩的显示

• 设计思想
• 实现效果
• 源代码

设计思想

首先创建所有页面的故事版，包括，登录、注册与成绩页面


接着设置故事版的关联代码，如下图所示为用户名与密码UITextField的关联

再进行一些空间的格式类型等设置，如下图所示为TableViewCell单元格属性的设置

最后在增加增删改查的代码，完成设计

实现效果

注册账号：lct，密码：lct，登录系统

进入系统，看到学生成绩信息，进行编辑操作/删除操作/增加操作

源代码

注：@开头的这些代码都是需要关联控键，都需要自行在故事板中(Storyboards)进行关联
登录界面

//登录界面
import  UIKit

class LoginViewController : UIViewController   
    @IBOutlet weak var userId: UITextField!
    @IBOutlet weak var password: UITextField!
    override func viewDidLoad() 
        super.viewDidLoad()
        NotificationCenter.default.addObserver(self, selector: #selector(autoFillInfomation(_:)), name: Notification.Name(rawValue: "RegisterNotification"), object: nil)
    
    override func didReceiveMemoryWarning() 
        super.didReceiveMemoryWarning()
        NotificationCenter.default.removeObserver(self)
    
    @objc func autoFillInfomation(_ notification: Notification)  
        let userInfo = notification.userInfo!
        let userId1 = userInfo["userId"] as! String
        let password1 = userInfo["password"] as! String
        userId.text = userId1
        password.text = password1
       // users[userId1] = password1
    

注册界面

// 注册界面
import UIKit
class RegisterViewController : UIViewController
    @IBOutlet weak var userId: UITextField!
    @IBOutlet weak var password: UITextField!
    override func viewDidLoad() 
        super.viewDidLoad()
    
    override func didReceiveMemoryWarning() 
        super.didReceiveMemoryWarning()
    
    @IBAction func back(_ sender: Any) 
        self.dismiss(animated: true, completion: nil)
    
    
    @IBAction func register(_ sender: Any) 
        
        self.dismiss(animated: true)  () -> Void in
            
            let userInfo = ["userId" :
                self.userId.text!, "password": self.password.text!]
            NotificationCenter.default.post(name: Notification.Name(rawValue: "RegisterNotification"),object:nil,userInfo: userInfo)
            
         
    

定义数据字段

//定义数据字段
import UIKit
class Student:NSObject
    var name:String
    var score:Int
    
    init(name:String,score:Int)
        self.name=name
        self.score=score
        super.init()
    

定义增加、删除、移动等操作

//定义增加、删除、移动等操作
import UIKit

class StudentsInfo
    var StudentsCollection=[Student]()
    init()
        let nameOfStudents=["zhangyi","zhanger","zhangsan","zhangsi","zhangwu"]
        let scoreOfStudents=[99,98,97,99,98]
        for i in 0...(nameOfStudents.count-1)
            let theStudent=Student(name:nameOfStudents[i],score:scoreOfStudents[i])
            StudentsCollection.append(theStudent)
        
    
    func addStudent() -> Student 
        let theStudent = Student(name: "新同学",score:100)
        StudentsCollection.append(theStudent)
        return theStudent
    
    func deleteStudent(_ theStudent:Student) 
        if let theIndex = StudentsCollection.index(of: theStudent)
            StudentsCollection.remove(at: theIndex)
        
    
    
    func transferPosition(sourceIndex: Int, destinationIndex: Int) 
        if sourceIndex != destinationIndex 
            let theStudent = StudentsCollection[sourceIndex]
            StudentsCollection.remove(at: sourceIndex)
            StudentsCollection.insert(theStudent, at: destinationIndex)
        
        return
