今天我們把tableView做更新

func updateData(){
    users = []
    let allorders = realm.objects(Users.self)
    guard allorders.count > 0 else { print("nil");return }
    for i in 1...allorders.count{
        users.append(structData(setUser: allorders[i-1].name, setPassword: String(allorders[i-1].password), setEmail : allorders[i-1].email, setId : allorders[i-1].UserID))//把每個資料寫進剛剛宣告得空陣列
    }
    MyTableView?.reloadData()//更新TableView
}  

刪除功能：
我們用primaryKey去做刪除我們選定的資料，之後除了要再tableView做deleteRows，realm也要寫delete把他刪除

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let userId = NSPredicate(format: "UserID = %@", self.users[indexPath.row].setId)
        
    let deleteUser = realm.objects(Users.self).filter(userId)
        
    let deleteAction = UIContextualAction(style:.destructive, title: "delete") { [self] (action , sourceView ,complete) in
            
        self.users.remove(at: indexPath.row)
        self.MyTableView.deleteRows(at: [indexPath], with: .top)
            
        try! self.realm.write{
            realm.delete(deleteUser)
           }
        complete(true)  
}
        

最後我們可以，創建一個UserVC，然後再didSelectRowAt，把點擊使用者會跳頁的功能做出來，當然裡面你可以在客製化你想要顯示的內容，我這邊是顯示使用者名稱而已

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let switchToSecondScreen = UserVC()
    switchToSecondScreen.UserVariable = users[indexPath.row].setUser
    self.navigationController?.pushViewController(switchToSecondScreen, animated: true)
}

UserVC:

import UIKit

class UserVC: UIViewController {

    @IBOutlet var UserNameLabel: UILabel!
    
    var UserVariable: String!
    
    override func viewDidLoad() {
        
        UserNameLabel.text = UserVariable
        
        super.viewDidLoad()
    }
}

記得用一個變數去儲存我們要傳的值會比較好，可以避免掉程式不會執行的錯誤

今天實作就到這邊～
