NSString到wchar_t *？ [英] NSString to wchar_t*?

问题描述

我似乎找不到一个很好的内置方式将NSString转换为wchar_t ...任何提示如何做到这一点？任何苹果公开在NSString类是c字符串（char *）或unichars，但没有wchar *。

I can't seem to find a good built-in way to convert an NSString to wchar_t... any tips on how to do this? Anything Apple exposes on the NSString class is for c-strings (char*) or for unichars, but nothing for wchar*.

推荐答案

[urString cStringUsingEncoding:NSUTF16LittleEndianStringEncoding]

wchar_t 是编译器特定的。假设你有Win32 wchar_t ，那么UTF16很少的结尾编码会做到。对于Unix wchar_t ，您可能需要NSUTF32编码系列，您的平台选择端序。

wchar_t is compiler specific. Assuming you wan the Win32 wchar_t, then UTF16 little ending encoded will do it. For Unix wchar_t you may need the NSUTF32 encoding family, with your platform of choice endianess.
