ios - Swift 中的数组 - 如何添加图像

Question

我正在制作一个应用程序，将分数保持在 1 到 20 之间，然后在分数 >= 21 时显示图像。但是我不知道如何解决这个问题，我有一个标签显示用户分数整数。有没有办法可以在 20 后将图像添加到数组中？或者有没有办法在分数 >= 21 时添加一个字符串，表示“Bullseye”字符串或图像。我只是不知道最好的方法有什么帮助吗？

import UIKit

class ViewController: UIViewController {
//Below are all of the labels at the top of AZG
@IBOutlet weak var user1name: UILabel!
@IBOutlet weak var user2name: UILabel!
@IBOutlet weak var lbl_currentPlayer: UILabel!
@IBOutlet weak var user1score: UILabel!
@IBOutlet weak var user2score: UILabel!



//Below are all the declared variables
var usernames = ["Big Meat ", "J Hooks "]
var currentPlayer = 0
var scores = [0,0]
var count = 0
var sdCount = 0

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

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func newGame() {
    user1score.text = "\(count)"
    user2score.text = "\(count)"
    user1name.text = "\(usernames[0])"
    user2name.text = "\(usernames[1])"
    lbl_currentPlayer.text = usernames[currentPlayer]
    scores = [0,0]
}

func setupGame() {
    user1score.text = "\(count)"
    user2score.text = "\(count)"
    user1name.text = "\(usernames[0])"
    user2name.text = "\(usernames[1])"
    lbl_currentPlayer.text = usernames[currentPlayer]
}

func updateTurn() {
    lbl_currentPlayer.text = usernames[currentPlayer]
    user1score.text = "\(scores[0])"
    user2score.text = "\(scores[1])"
}

func attackTurnUpdate() {
    currentPlayer = 1 - currentPlayer
}

func resetAttackTurn() {
    currentPlayer = 1 - currentPlayer
}

func missedNextTurn() {
    currentPlayer = 1 - currentPlayer
}

func suddenDeath() {
    sdCount = sdCount++
}

func takeStepBack() {
}

func bullseyeDisplay() {

}

@IBAction func hitSingle(sender: AnyObject) {
    scores[currentPlayer]++
    updateTurn()
}

@IBAction func nextTurn(sender: AnyObject) {
    currentPlayer = 1 - currentPlayer
    updateTurn()
}

只需将图像添加到界面构建器中的 View (在代码中使用适当的 IBOutlet)并在其上设置“隐藏”即可。

然后当你想显示图片时，只需更改hidden的值即可:

my image.hidden = false
