NSMutableAttributedString

　　　　　let testAttributes = [NSAttributedStringKey.foregroundColor: UIColor.blue, NSAttributedStringKey.backgroundColor: UIColor.yellow,NSAttributedStringKey.strikethroughStyle:1] as [NSAttributedStringKey : Any]

let testAttributeString = NSAttributedString(string: "富文本测试", attributes:testAttributes)

self.testLabel.attributedText = testAttributeString

let prefix = "￥" + "100"

let suffix = "￥" + "200"

let string = prefix + suffix

let myAttribute = [NSAttributedStringKey.foregroundColor: UIColor.lightGray,

NSAttributedStringKey.strikethroughStyle: NSUnderlineStyle.styleSingle.rawValue,

NSAttributedStringKey.font: UIFont.systemFont(ofSize: 13)] as [NSAttributedStringKey : Any]

let redAttribute = [NSAttributedStringKey.foregroundColor: UIColor.red,

NSAttributedStringKey.font: UIFont.systemFont(ofSize: 15)] as [NSAttributedStringKey : Any]

let attString = NSMutableAttributedString(string: string)

attString.addAttributes(myAttribute, range: NSRange.init(location: prefix.count, length: suffix.count))
