調色APP

這次我試著做了皮卡丘的app，並試著讓牠穿上虎紋裝

程式碼:

import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {
 super.viewDidLoad()
 // Do any additional setup after loading the view, typically from a nib.
 }
 @IBOutlet weak var image1: UIImageView!
 
 @IBAction func red(_ sender: Any) {
 image1.backgroundColor = UIColor(red: CGFloat(red1.value), green: CGFloat(green1.value), blue: CGFloat(blue1.value), alpha: CGFloat(alpha1.value))
 }
 
 

@IBAction func green(_ sender: Any) {
 image1.backgroundColor = UIColor(red: CGFloat(red1.value), green: CGFloat(green1.value), blue: CGFloat(blue1.value), alpha: CGFloat(alpha1.value))
 }
 @IBAction func blue(_ sender: Any) {
 image1.backgroundColor = UIColor(red: CGFloat(red1.value), green: CGFloat(green1.value), blue: CGFloat(blue1.value), alpha: CGFloat(alpha1.value))
 }
 

@IBAction func alpha(_ sender: Any) {
 image1.backgroundColor = UIColor(red: CGFloat(red1.value), green: CGFloat(green1.value), blue: CGFloat(blue1.value), alpha: CGFloat(alpha1.value))
 }
 @IBOutlet weak var red1: UISlider!
 
 @IBOutlet weak var green1: UISlider!
 @IBOutlet weak var blue1: UISlider!
 @IBOutlet weak var alpha1: UISlider!
}

心得:這次學習到slider的用法,對於取得數值的方法有了初步的概念
