用于.cgColor颜色的UIColor扩展？

Question

这里是我的UIColor扩展：

extension UIColor { 
    // custom red 
    public class var customRed: UIColor { 
     return UIColor(red: 244/255, green: 59/255, blue: 59/255, alpha: 1) 
    } 
} 

如何追加cgColors呢？

UIColor.someColor.cgColor 

Answer 1

与此

extension CGColor{ 
    public class var customRed: CGColor { 
     return UIColor(red: 244/255, green: 59/255, blue: 59/255, alpha: 1).cgColor 
    } 
} 

尝试使用它

self.view.layer.borderColor = CGColor.customRed 

希望这有助于你
