ios - NSMutableAttributedString 添加多个隐藏文本的属性

Question

let text = "By accepting  you agree to our Terms of Service and Privacy Policy."
let attr = NSMutableAttributedString(string: text)

attr.setAttributes([.underlineStyle: 1, .foregroundColor: #colorLiteral(red: 0.7294117647, green: 0.6235294118, blue: 0.2823529412, alpha: 1).cgColor ],
                   range: (text as NSString).range(of: "Terms of Service"))

attr.setAttributes([.underlineStyle: 1, .foregroundColor: #colorLiteral(red: 0.7294117647, green: 0.6235294118, blue: 0.2823529412, alpha: 1).cgColor ],
                   range: (text as NSString).range(of: "Privacy Policy."))

This is the showing in terminal

-[__NSCFType set]: unrecognized selector sent to instance 0x6000039b2ca0

添加单个属性时工作正常

在 iOS Simulator 13.2.2、Xcode 11.2.1、Swift 5 上运行代码

这里是您需要将 cgColor 转换为 UIColor 才能使用 foregroundColor 属性

attr.setAttributes([.underlineStyle: 1, .foregroundColor: UIColor(red: 1, green: 0.556, blue: 0.232, alpha: 1)],
                      range: (text as NSString).range(of: "Terms of Service"))



 attr.setAttributes([.underlineStyle: 1, .foregroundColor: UIColor(red: 1, green: 0.556, blue: 0.232, alpha: 1) ],
                          range: (text as NSString).range(of: "Privacy Policy."))
