swift - 快速从 NSMutableString 获取字符串

Question

从 NSMutableString 获取 String 的正确方法是什么？我目前正在使用:

var mutableString = NSMutableString(string: string)
var string = mutableString.substring(from: 0)

这看起来有点hackish...

谢谢

只需将 NSMutableString 转换为 String:

var mutableString = NSMutableString(string: "Example")
var string = String(mutableString)

或者:

var mutableString = NSMutableString(string: "Example")
var string = mutableString as String
