UnsafeMutablePointer <Int8> 转换为UTF8字符串

Question

I have a UnsafeMutablePointer pointing at a C string, I want to convert the bytes at this pointer to a Swift String, the data is a C string, so UTF8.

Is it possible to iterate byte by byte until NULL? Or some easier way?

Answer 1

CChar是Int8的别名，因此您可以在此处使用基于CChar的方法 。

let str = String(cString: pointer)
