我得到 HSB 為 29、90、100。如何將其轉換為 0...1 范圍？UIColor 只在這個范圍內初始化，所以我有一個問題。
let red: CGFloat = 1
let green: CGFloat = 0.5372
let blue: CGFloat = 0.0941
let hueOut = 29
let satOut = 90
let brightnessOut = 100
let color = UIColor(red: red, green: green, blue: blue, alpha: 1.0)
///r 1,0 g 0,537 b 0,094 a 1,0
let color2 = UIColor(hue: hueOut, saturation: satOut, brightness: brightnessOut, alpha: 1.0)
///r -9,0 g 0,0 b -3,0 a 1,0
uj5u.com熱心網友回復：
看起來你的色調范圍是0...360，你的飽和度和亮度是0...100。您只需要將整數轉換為 double 并除以 360 或 100：
let color2 = UIColor(hue: Double(hueOut)/360, saturation: Double(satOut)/100, brightness: Double(brightnessOut)/100, alpha: 1.0)
這將導致 r 1.0 g 0.535 b 0.1 a 1.0
