Star War 光劍

這次的調色大師app選用Star War為主題

其中有一個特別的“天選之劍”

就是運用了剛學到的亂數

運行畫面如下

程式碼

import UIKit
class ViewController: UIViewController {
@IBOutlet weak var blueValueLabel: UILabel!
@IBOutlet weak var greenValueLabel: UILabel!
@IBOutlet weak var redValueLabel: UILabel!
@IBOutlet weak var Redslider: UISlider!
@IBOutlet weak var Greenslider: UISlider!
@IBOutlet weak var Blueslider: UISlider!
@IBOutlet weak var Alphaslider: UISlider!
@IBOutlet weak var StarladyImageview: UIImageView!
@IBAction func RandomColor(_ sender: UIButton) {
let red = CGFloat.random(in: 0...1)
let green = CGFloat.random(in: 0...1)
let blue = CGFloat.random(in: 0...1)
let alpha = CGFloat.random(in: 0...1)
StarladyImageview.backgroundColor = UIColor(red: red, green: green, blue: blue, alpha: alpha)
}
@IBAction func Colorchange(_ sender: UISlider) {
StarladyImageview.backgroundColor = UIColor(red: CGFloat(Redslider.value), green: CGFloat(Greenslider.value), blue: CGFloat(Blueslider.value), alpha: CGFloat(Alphaslider.value))
redValueLabel.text = String(format: "%.2f", Redslider.value)
greenValueLabel.text = String(format: "%.2f", Greenslider.value)
blueValueLabel.text = String(format: "%.2f", Blueslider.value)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
}
