Question

您好我正在尝试在Swift3中使用addAttribute。

我希望只设置粗体IDNAME。

这是我想要的。

let boldUsername = NSMutableAttributedString(string: "IDNAME hi nice 2 meet you :D #HELLOW")


//            boldUsername.addAttribute(NSFontAttributeName, value: UIFont(name: "SFUIText-Bold", size: 14)!, range: (boldUsername.string as NSString).range(of: " "))

            boldUsername.addAttribute(NSFontAttributeName, value: UIFont(name: "SFUIText-Bold", size: 14)!, range: NSRange(location: 0, length: 5))

我如何获得IDNAME的索引，即每次都不同？

- ＆GT;有没有办法分割空间并获得索引？

你需要做这样的事情。

let personName = "Black"
let wholeStr = "\(personName) hi nice 2 meet you :D #HELLOW"
let boldUsername = NSMutableAttributedString(string: wholeStr)
boldUsername.addAttribute(NSFontAttributeName, value: UIFont(name: "SFUIText-Bold", size: 14)!, range: (wholeStr as NSString).range(of: personName))

如何在swift 3
