如何在swift文件中获取类的引用，并在另一个swift文件中进行编码？ -xcode /迅速

Question

Im new to swift / Xcode and would like to know how to answer this specific question.

The instruction states that i have to " Get a reference to your model in your TableViewController"

So my question is: How do i get a reference to my Model (Model.swift) in my other swift file (TableViewController.swift) ? What do i have to code in my TableViewController to get a reference?

My Model.swift file contains the following code:

import UIKit

class Restaurant
{
  var name: String
  var phone: String

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

Thanks.

You can create an instance of Restaurant, possibly in your TableViewController. Let us assume, you are displaying an array of restaurants in your table view.

Do this-

1. Define an array inside your table view controller

    var restaurants = [Restaurant]() 

2. Somewhere in your controller, say in viewDidLoad, create a few restaurant objects and add it the above array

    //Create few restaurant objects restaurants.append(Restaurant(name:"Rest1", phone:"123")) restaurants.append(Restaurant(name:"Rest2", phone:"1234")) restaurants.append(Restaurant(name:"Rest3", phone:"12345")) 

3. Load the table view with the above objects via the data source delegates.

In swift you don't need to import Model.swift, etc, once defined in a file, it is automatically available to the rest of the app unless you restrict its access using access specifiers.

HTH.
