最近碰到字符串编码转换的问题，简单记录下
Ascii 转unicode
std::wstring AsciiToWide(std::string _strSrc)
{
NSString *_nsstr = [NSString stringWithCString:_strSrc.c_str() encoding:NSASCIIStringEncoding];
NSString *urlStringUTF8 = [_nsstr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
const char* _cdata = [urlStringUTF8 cStringUsingEncoding:NSUnicodeStringEncoding];
std::wstring _wstr((wchar_t*)_cdata);
return _wstr;
}
unicode 转 Ascii
std::string WideToAscii(std::wstring _strSrc)
{
wchar_t* _csrc = const_cast<wchar_t*>(_strSrc.c_str());
NSString *_nsstr = [NSString stringWithCString:(char*)_csrc encoding:NSUnicodeStringEncoding];
NSString *urlStringUTF8 = [_nsstr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
const char* _cdata = [urlStringUTF8 cStringUsingEncoding:NSASCIIStringEncoding];
std::string _str(_cdata);
return _str;
}
utf8 转 Ascii
std::string UTF8ToAscii(std::string _strSrc)
{
NSString *_nsstr = [NSString stringWithCString:_strSrc.c_str() encoding:NSUTF8StringEncoding];
NSString *urlStringUTF8 = [_nsstr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
const char* _cdata = [urlStringUTF8 cStringUsingEncoding:NSUTF8StringEncoding];
std::string _str(_cdata);
return _str;
}
Ascii 转 utf8
std::string AsciiToUTF8(std::string _strSrc)
{
NSString *_nsstr = [NSString stringWithCString:_strSrc.c_str() encoding:NSASCIIStringEncoding];
NSString *urlStringUTF8 = [_nsstr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
const char* _cdata = [urlStringUTF8 cStringUsingEncoding:NSUTF8StringEncoding];
std::string _str(_cdata);
return _str;
}
