今天白白给大家分享一个转码的工具函数，如果大家需要在项目中显示中文，可以直接使用，Android和IOS部分都是通用的，不用太麻烦的分平台操作。

首先，这个函数是这样的，可以直接拖进去用
<span style="font-size:18px;"><span style="font-size:18px;">#ifndef __TRANSFORMUTF__
#define __TRANSFORMUTF__
#include "../../../win32-specific/icon/include/iconv.h"
#pragma comment(lib,"libiconv.lib")
#include "cocos2d.h"
using namespace std;
//使用方法：string s = GBtoUTF("确定"); 或者 <span style="font-family: Arial, Helvetica, sans-serif;">string s = </span><span style="font-family: Arial, Helvetica, sans-serif;">UTFtoGB</span><span style="font-family: Arial, Helvetica, sans-serif;">("确定");</span>
static int code_convert( const char *from_charset, const char *to_charset, const char *inbuf, size_t inlen, char *outbuf, size_t outlen )
{
iconv_t cd;
const char *temp = inbuf;
const char **pin = &temp;
char **pout = &outbuf;
memset(outbuf,0,outlen);
cd = iconv_open(to_charset,from_charset);
if(cd==0) return -1;
if(iconv(cd,pin,&inlen,pout,&outlen)==-1) return -1;
iconv_close(cd);
return 0;
}
/*UTF8 To GB2312*/
static string UTFtoGB( const char *inbuf )
{
size_t inlen = strlen(inbuf);
char * outbuf = new char[inlen * 2 + 2];
string strRet;
if(code_convert("utf-8", "gb2312", inbuf, inlen, outbuf, inlen * 2 + 2) == 0)
{
strRet = outbuf;
}
delete [] outbuf;
return strRet;
}
/*GB2312 To UTF8*/ //使用中文时用该函数转换
static string GBtoUTF( const char *inbuf )
{
size_t inlen = strlen(inbuf);
char * outbuf = new char[inlen * 2 + 2];
string strRet = "";
if(code_convert("gb2312", "utf-8", inbuf, inlen, outbuf, inlen * 2 + 2) == 0)
{
strRet = outbuf;
}
delete [] outbuf;
return strRet;
}
#endif</span></span>好了，这样大家就能直接用了，这里使用到了iconv这个库，然后大家将下载到的iconv库解压至项目根目录。也就是和cocos2dx, extensions这些库的同级目录。
将这个库拖到ios里面，这样ios这边就能直接工作了，
对于windows这边，配置一下库就可以了
Android环境，大家照下面方法做就ok
编写iconv库所需的Android.mk。
这步要仔细看了，很多文章这步没写清楚，让我走了许多冤枉路。
进入到刚才解压出的iconv文件夹，用记事本之类的建立一个Android.mk文件，
将下面内容复制到这个文件中，不要写错，很重要的
<span style="font-size:18px;">LOCAL_PATH:= $(call my-dir) #libiconv.so include $(CLEAR_VARS) LOCAL_MODULE := libiconv LOCAL_CFLAGS := -Wno-multichar -DAndroid -DLIBDIR="c" -DBUILDING_LIBICONV -DIN_LIBRARY LOCAL_SRC_FILES := libcharset/lib/localcharset.c lib/iconv.c lib/relocatable.c LOCAL_C_INCLUDES += $(LOCAL_PATH)/include $(LOCAL_PATH)/libcharset $(LOCAL_PATH)/lib $(LOCAL_PATH)/libcharset/include $(LOCAL_PATH)/srclib include $(BUILD_STATIC_LIBRARY)</span>
编写Android项目里面的Android.mk文件，如下图所示
cocos2d-x3.0以前的版本：
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes LOCAL_C_INCLUDES += $(LOCAL_PATH)/../iconv/include $(LOCAL_PATH)/../libiconv/libcharset $(LOCAL_PATH)/../libiconv/lib $(LOCAL_PATH)/../libiconv/libcharset/include $(LOCAL_PATH)/../libiconv/srclib $(LOCAL_PATH)/../iconv LOCAL_WHOLE_STATIC_LIBRARIES += cocos2dx_static LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static LOCAL_WHOLE_STATIC_LIBRARIES += box2d_static LOCAL_WHOLE_STATIC_LIBRARIES += chipmunk_static LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static LOCAL_WHOLE_STATIC_LIBRARIES += libiconv include $(BUILD_SHARED_LIBRARY) $(call import-module,cocos2dx) $(call import-module,cocos2dx/platform/third_party/android/prebuilt/libcurl) $(call import-module,CocosDenshion/android) $(call import-module,extensions) $(call import-module,external/Box2D) $(call import-module,external/chipmunk) $(call import-module,iconv)
LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../iconv/include $(LOCAL_PATH)/../../libiconv/libcharset $(LOCAL_PATH)/../../libiconv/lib $(LOCAL_PATH)/../../libiconv/libcharset/include $(LOCAL_PATH)/../../libiconv/srclib $(LOCAL_PATH)/../../iconv LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static LOCAL_WHOLE_STATIC_LIBRARIES += cocostudio_static # LOCAL_WHOLE_STATIC_LIBRARIES += box2d_static # LOCAL_WHOLE_STATIC_LIBRARIES += cocosbuilder_static # LOCAL_WHOLE_STATIC_LIBRARIES += spine_static # LOCAL_WHOLE_STATIC_LIBRARIES += cocostudio_static # LOCAL_WHOLE_STATIC_LIBRARIES += cocos_network_static # LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static LOCAL_WHOLE_STATIC_LIBRARIES += libiconv include $(BUILD_SHARED_LIBRARY) $(call import-module,.) $(call import-module,audio/android) $(call import-module,extensions) $(call import-module,editor-support/cocostudio) # $(call import-module,Box2D) # $(call import-module,editor-support/cocosbuilder) # $(call import-module,editor-support/spine) # $(call import-module,editor-support/cocostudio) # $(call import-module,network) # $(call import-module,extensions) $(call import-module,iconv)
