iOS：在swift中将UnsafeMutablePointer转换为String？

正如标题所说,在 swift中将UnsafeMutablePointer转换为String的正确方法是什么？

//lets say x = UnsafeMutablePointer<Int8> 

var str = x.memory.????

我尝试使用x.memory.description显然它是错误的,给我一个错误的字符串值.

解决方法

如果指针指向以NUL结尾的UTF-8字节的C字符串,则可以执行以下操作：

import Foundation

let x: UnsafeMutablePointer<Int8> = ...
// or UnsafePointer<Int8>
// or UnsafePointer<UInt8>
// or UnsafeMutablePointer<UInt8>

let str = String(cString: x)
