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(redAttribute, range:NSRange.init(location: 0, length: prefix.count))
attString.addAttributes(myAttribute, range: NSRange.init(location: prefix.count, length: suffix.count))
self.titleLabel.attributedText = attString
