轉吧轉吧轉吧骰子～swift

使用到random, for_in,animatedImageNamed,[UIImageView]!,motionBegan

稍微設計了一下介面，

還有更多細節想做，想用一些動態似乎要用swiftUI比較容易，

利用animatedImageNamed把6張圖變成骰子動態gif,把轉速度改成duration: 0.2 秒，看起來就可以避掉看起來笨拙的問題。

手機搖擺的motion感測有3種，
motionbegan
motionended
motioncanceled
三個的用法要再研究一下，
搖起來不太順暢…

import UIKit


class ViewController: UIViewController {

    

    @IBOutlet var dicebtn: [UIImageView]!
    @IBOutlet weak var pointText: UILabel!
    @IBOutlet weak var startbtn: UIButton!
    @IBOutlet weak var stopbtn: UIButton!
    
    
    func diceAnimationImage(){
        let animatedImage = UIImage.animatedImageNamed("dice", duration: 0.2)
        dicebtn[0].image = animatedImage
        dicebtn[1].image = animatedImage
        dicebtn[2].image = animatedImage
        dicebtn[3].image = animatedImage
        dicebtn[4].image = animatedImage
        dicebtn[5].image = animatedImage
        pointText.text = String("?")
        
    }
    
    func randomdice(){
        var sum = 0
        for dice in dicebtn{
            let dicenumner = Int.random(in: 1...6)
            sum = sum + dicenumner
            dice.image = UIImage(named: "dice\(dicenumner)")
            pointText.text = String(Int(sum))
        }
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        randomdice()
        stopbtn.isHidden = true
        
        
    }
    
    
    
    override func motionBegan(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
        if motion == .motionShake {
            diceAnimationImage()
            startbtn.isHidden = true
            stopbtn.isHidden = false
        }
        
    }
    
    
    @IBAction func playbtn(_ sender: Any) {
        diceAnimationImage()
        startbtn.isHidden = true
        stopbtn.isHidden = false

    @IBAction func playstop(_ sender: Any) {
        startbtn.isHidden = false
        stopbtn.isHidden = true
        randomdice()
        
    }
    
}
