swift - 如何使用struct在swift中显示UIImage

Question

我在使用 UIImage 时遇到问题，我正在尝试将图像显示到 ImageView 中，但我在结构方面遇到问题...有人可以帮助我吗，这是我的代码。

import UIKit

struct Question {
    var Question: String!
    var Answers: [String]!
    var Answer: Int!
    var Img: UIImage?
}

class ViewController: UIViewController {

@IBOutlet weak var questionLabel: UILabel!
@IBOutlet var Buttons: [UIButton]!
@IBOutlet weak var imgView: UIImageView! //This part Im pretty sure that i need to connect to the var Img:UIImage? but Im not sure how?

//Creation of a variable to hold the Quesitons,Question Number and Answer Number

var Questions = [Question]()
var questionNumber = Int()
var answerNumber = Int()

override func viewDidLoad() {
    super.viewDidLoad()
    //Creation of the Question
    Questions = [Question(Question: "Who is this guy?", Answers: ["Alex","Roberto","Joey","Will"], Answer: 2, Img: UIImage.self(named:"steve_jobs"))]

    //We call our funciton into the viewDidLoad
    pickQuestion()
}

Answer 1

使用结构体中的图像来设置 UIImageView 的图像属性:

imgView.image = Questions[questionNumber].Img
