[英]Swift - Scroll a UIScrollView by tapping button inside a ViewController inside the ScrollView
[英]Swift - Locking/tapping a button
我正在用骰子制作游戲。 這個想法是保持/鎖定骰子。 我把骰子做成按鈕,所以現在可以點擊它們了。 示例:我拋出“ 6”和“ 1”。 我點擊“ 6”,所以現在只拋出“ 1”。
我有點迷失了這個,我需要讓布爾值容納它們嗎? 這是我的代碼。 我實際上不知道從哪里開始。
class ViewController: UIViewController {
@IBOutlet weak var dice1: UIButton!
@IBOutlet weak var dice2: UIButton!
var audioPlayer:AVAudioPlayer!
var randomDiceIndex1 : Int = 0
var randomDiceIndex2 : Int = 0
let diceArray = ["dice1", "dice2", "dice3", "dice4", "dice5", "dice6"]
func playSoundWith(fileName: String, fileExtenstion: String) -> Void {
let audioSourceURL: URL!
audioSourceURL = Bundle.main.url(forResource: fileName,
withExtension: fileExtenstion)
if audioSourceURL == nil {
print("Geluid werkt niet")
} else {
do {
audioPlayer = try AVAudioPlayer.init(contentsOf:
audioSourceURL!)
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch {
print(error)
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
updateDiceImages()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
@IBAction func buttonPressed(_ sender: Any) {
updateDiceImages()
playSoundWith(fileName: "dobbelstenen", fileExtenstion: "m4a")
}
func updateDiceImages(){
randomDiceIndex1 = Int(arc4random_uniform(6))
randomDiceIndex2 = Int(arc4random_uniform(6))
dice1.setImage(UIImage(named: diceArray[randomDiceIndex1]), for:
.normal)
dice2.setImage(UIImage(named: diceArray[randomDiceIndex2]), for:
.normal)
}
override func motionEnded(_ motion: UIEventSubtype, with event:
UIEvent?) {
updateDiceImages()
playSoundWith(fileName: "dobbelstenen", fileExtenstion: "m4a")
}
}
是的,您可以使用布爾值來存儲哪個骰子被鎖定。
var dice1Locked = false
var dice2Locked = false
在按鈕的@OBAction
中(即,點擊按鈕時),切換布爾值:
dice1Locked = !dice1Locked
然后在updateDiceImages
,在更改其圖像之前檢查骰子是否已鎖定:
if !dice1Locked {
randomDiceIndex1 = Int(arc4random_uniform(6))
dice1.setImage(UIImage(named: diceArray[randomDiceIndex1]), for:
.normal)
}
if !dice2Locked {
randomDiceIndex2 = Int(arc4random_uniform(6))
dice2.setImage(UIImage(named: diceArray[randomDiceIndex2]), for:
.normal)
}
我還建議您為骰子創建模型,而不要使用按鈕:
struct Dice {
var number: Int
var locked: Bool
}
