Using struct to create detail view controller from tableview

Question

First of all, I am a beginner! So it's a bit complicated, but basically I am trying to create a separate view controller that displays information held in a struct/string with objects. I am making a directory. I have two controllers, one for the tableView (called DirectoryTableViewController ) and one for the detail view (called FacultyViewController ) and then I have a swift file (called People) that has manages the String. I am eventually going to add name, phone, email and an image to the String , but for now I am just doing the names.

My problem is that it is working and I need some pointers. Thanks!!

Here is my DirectoryTableView:

import UIKit

struct peoples {
  var teacherString: String!
  var image: UIImage!
}

class DirectoryTableViewController: UITableViewController {

  var detailViewController: DetailViewController? = nil
  var array : [People]!

  override func viewDidLoad() {
    super.viewDidLoad()
    print(array)
  }

  override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
  }


  override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
  }

  override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return array.count
  }


  override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("directoryCell", forIndexPath: indexPath)

    let person = array[indexPath.row]
    cell.textLabel!.text = person.teacherString



    return cell
  }

  override func tableView(tableView: UITableView, moveRowAtIndexPath fromIndexPath: NSIndexPath, toIndexPath: NSIndexPath) {

  }
}

Here is my NewViewController:

import UIKit
class NewViewController: UIViewController {

  @IBOutlet weak var nameTextField: UITextField!
  @IBOutlet weak var phoneTextField: UITextField!
  @IBOutlet weak var emailTextTield: UITextField!
  var array : [People] = []

  override func viewDidLoad() {
    super.viewDidLoad()
  }

  @IBAction func crateObjectButton(sender: AnyObject) {

    let object = People(name: nameTextField.text! , phone: phoneTextField.text!, email: emailTextTield.text!)
    array.append(object)
    performSegueWithIdentifier("TeacherData", sender: self)
  }

  override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "TeacherData" {
        let dvc =  segue.destinationViewController as? DirectoryTableViewController
        dvc!.array = array

    }
  }
}

Here is People.swift (model):

import Foundation

class People {
  var name : String
  var phone: String
  var email: String

  init(name: String, phone: String, email: String) {
    self.name = name
    self.phone = phone
    self.email = email
  }
}

Thanks again!

Answer 1

As per your question , you have to make a model

import Foundation

class People {
    var name : String
    var phone: String
    var email: String

    init(name: String, phone: String, email: String) {
    self.name = name
    self.phone = phone
    self.email = email
    }
}

and make a view controller from where you gather all these details for eg: like this

import UIKit
class ViewController: UIViewController {

    @IBOutlet weak var nameTextField: UITextField!
    @IBOutlet weak var phoneTextField: UITextField!
    @IBOutlet weak var ageTextTield: UITextField!
    var array : [People] = []
    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func crateObjectButton(sender: AnyObject) {

        let object = People(name: nameTextField.text! , phone: phoneTextField.text!, email: ageTextTield.text!)
        array.append(object)
        performSegueWithIdentifier("TeacherData", sender: self)  
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "TeacherData" {
            let dvc =  segue.destinationViewController as? TableviewController
               dvc!.array = array

        }
    }
}

and this segue take you to the tableviewcontroller where in viewdidLoad i am printing the array of teachers.

import UIKit
class TableviewController: UITableViewController {
    var array : [People]!
    override func viewDidLoad() {
        super.viewDidLoad()
        print(array)
    }
}

and you go to the deatil view controller of a selected teacher by using this method:

 override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        object =  array![indexPath.row]
        performSegueWithIdentifier("yourdetailviewcontrollersegue", sender: self) 
    }
