Swift 2.1 [UInt8] --utf8->细绳?
问题描述：
我知道Stack Overflow和其他地方都存在类似的问题.但是它似乎也发展了很多.
I know questions like this exist on both Stack Overflow and elsewhere. But it seems to have evolved a lot as well.
给出一个UInt8列表(基本上是一个swift字节数组)，将它隐蔽到一个迅速的String上最简单/惯用的方法是什么?
Given a list of UInt8 (a swift byte array basically), what is the easiest/idiomatic way to covert it to a swift String?
我对不使用NSData/NSString的方法特别感兴趣，因为如果Santa将Swift引入Linux的世界，那么无疑将没有NS库，并且我想知道该怎么做.只需Swift.
I'm particularly interested in the method that doesn't use NSData/NSString, since if Santa brings Swift to the world of Linux, it will undoubtedly be without the NS libraries, and I'd like to know how to do it in just Swift.
答
let buffUInt8: Array<UInt8> = [97, 98, 115, 100, 114, 102, 103, 104, 0]
// you need Int8 array
let buffInt8 = buffUInt8.map{ Int8(bitPattern: $0)}
let str = String.fromCString(buffInt8) // "absdrfgh"
或者您可以使用
String.fromCStringRepairingIllFormedUTF8(cs: UnsafePointer<CChar>) -> (String?, hadError: Bool)
