【ios開發/Xcode】使用UITableView完成學生信息及成績的顯示

• 設計思想
• 實現效果
• 源代碼

設計思想

首先創建所有頁面的故事版，包括，登錄、注冊與成績頁面


接著設置故事版的關聯代碼，如下圖所示為用戶名與密碼UITextField的關聯

再進行一些空間的格式類型等設置，如下圖所示為TableViewCell單元格屬性的設置

最后在增加增刪改查的代碼，完成設計

實現效果

注冊賬號：lct，密碼：lct，登錄系統

進入系統，看到學生成績信息，進行編輯操作/刪除操作/增加操作

源代碼

注：@開頭的這些代碼都是需要關聯控鍵，都需要自行在故事板中(Storyboards)進行關聯
登錄界面

//登錄界面
import  UIKitclass 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! Stringlet password1 = userInfo["password"] as! StringuserId.text = userId1password.text = password1// users[userId1] = password1}
}

注冊界面

// 注冊界面
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 inlet userInfo = ["userId" :self.userId.text!, "password": self.password.text!]NotificationCenter.default.post(name: Notification.Name(rawValue: "RegisterNotification"),object:nil,userInfo: userInfo)} }
}

定義數據字段

//定義數據字段
import UIKit
class Student:NSObject{var name:Stringvar score:Intinit(name:String,score:Int){self.name=nameself.score=scoresuper.init()}
}

定義增加、刪除、移動等操作

//定義增加、刪除、移動等操作
import UIKitclass 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: "新同學",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}
}
