Swift 3- PaintCode StyleKit颜色错误

Question

在升级到Swift 3和Xcode 8之前，我的StyleKit项目工作得非常好。这里是我的一些颜色代码：

//// Color Declarations 
    let purplebliss1 = UIColor(red: 0.212, green: 0.000, blue: 0.200, alpha: 1.000) 
    let purplebliss2 = UIColor(red: 0.043, green: 0.529, blue: 0.576, alpha: 1.000) 

//// Color Declarations 
    let venice1 = UIColor(red: 0.522, green: 0.847, blue: 0.808, alpha: 1.000) 
    let venice2 = UIColor(red: 0.031, green: 0.314, blue: 0.471, alpha: 1.000) 
    let aqua1 = UIColor(red: 0.149, green: 0.816, blue: 0.808, alpha: 1.000) 
    let aqua2 = UIColor(red: 0.102, green: 0.161, blue: 0.502, alpha: 1.000) 


    //// Color Declarations 
    let mantle1 = UIColor(red: 0.141, green: 0.776, blue: 0.863, alpha: 1.000) 
    let mantle2 = UIColor(red: 0.318, green: 0.290, blue: 0.616, alpha: 1.000) 

但是，现在说的这几行代码包含一个错误：

//// Gradient Declarations 
let purpleBliss = CGGradientCreateWithColors(CGColorSpaceCreateDeviceRGB(), [purplebliss2.CGColor, purplebliss2.blendedColorWithFraction(0.5, ofColor: purplebliss1).CGColor, purplebliss1.CGColor], [0, 0.27, 1])! 

//// Gradient Declarations 
    let mantle = CGGradientCreateWithColors(CGColorSpaceCreateDeviceRGB(), [mantle1.CGColor, mantle2.CGColor], [0, 1])! 

//// Gradient Declarations 
    let veniceBeach = CGGradientCreateWithColors(CGColorSpaceCreateDeviceRGB(), [venice2.CGColor, venice1.CGColor], [0, 1])! 
    let aqua = CGGradientCreateWithColors(CGColorSpaceCreateDeviceRGB(), [aqua1.CGColor, aqua2.CGColor], [0, 1])! 

错误的一贯说法是：

contexttual type 'CFArray' cannot be used with array literal 

我不知道如何解决这个问题。有什么建议？

谢谢大家:)

Answer 1

（更新）尝试创建一个CFArray这样的：

let purpleBliss = CGGradient(colorsSpace: CGColorSpaceCreateDeviceRGB(), 
            colors: [purplebliss2.cgColor, purplebliss2.blendedColorWithFraction(0.5, ofColor: purplebliss1).cgColor, purplebliss1.cgColor] as CFArray, 
           locations: [0, 0.27, 1])! 

其他梯度会是这样的：

let mantle = CGGradient(colorsSpace: CGColorSpaceCreateDeviceRGB(), 
         colors: [mantle1.cgColor, mantle2.cgColor] as CFArray, 
         locations: [0, 1])! 

let veniceBeach = CGGradient(colorsSpace: CGColorSpaceCreateDeviceRGB(), 
          colors: [venice2.cgColor, venice1.cgColor] as CFArray, 
          locations: [0, 1])! 

let aqua = CGGradient(colorsSpace: CGColorSpaceCreateDeviceRGB(), 
         colors:[aqua1.cgColor, aqua2.cgColor] as CFArray, 
         locations: [0, 1])! 

综上所述，变化在更新到swift 3时要做的是：

1. CGGradientCreateWithColors现在是CGGradient。
2. 您必须将参数的所有标签放在您的电话中（colorsSpace，colors和locations）。
3. .CGColor现在是.cgColor。
4. 在Swift 3中隐式转换为桥接类型已被删除，所以你必须自己施放CFArray。

值得一提的，是PaintCode 3完全支持出口斯威夫特3.
