必须使用使用Cocos2d-x源代码的形式打包

步骤:

1: 添加附件中的 XCForwarder.h 和 XCForwarder.m 到 cocos2d_libs.xcodeproj 中
2: 找到 CCFileUtils.cpp 文件
3: 在 #include "CCFileUtils.h" 下面添加 #include "XCForwarder.h"
4: 修改static Data getData(const std::string& filename, bool forString)为
	static Data getData(const std::string& filename, bool forString)
	{
	    if (filename.empty())
	    {
	  	  return Data::Null;
	    }
	
	    Data ret;
	    unsigned char* buffer = nullptr;
	    ssize_t size = 0;
	    size_t readsize;
	    const char* mode = nullptr;
	    if (forString)
	  	  mode = "rt";
	    else
	  	  mode = "rb";
	
	    do
	    {
	  	  // Read the file from hardware
	  	  std::string fullPath = FileUtils::getInstance()->fullPathForFilename(filename);
	#ifdef __XCForwarder_H__
	  	  buffer = XCForwarderLoadData(fullPath.c_str(), mode, &readsize);
	#else
	  	  FILE *fp = fopen(fullPath.c_str(), mode);
	  	  CC_BREAK_IF(!fp);
	  	  fseek(fp,0,SEEK_END);
	  	  size = ftell(fp);
	  	  fseek(fp,0,SEEK_SET);
	
	  	  if (forString)
	  	  {
	  		  buffer = (unsigned char*)malloc(sizeof(unsigned char) * (size + 1));
	  		  buffer[size] = '\0';
	  	  }
	  	  else
	  	  {
	  		  buffer = (unsigned char*)malloc(sizeof(unsigned char) * size);
	  	  }
	
	  	  readsize = fread(buffer, sizeof(unsigned char), size, fp);
	  	  fclose(fp);
	
	  	  if (forString && readsize < size)
	  	  {
	  		  buffer[readsize] = '\0';
	  	  }
	#endif
	
	    } while (0);
	
	    if (nullptr == buffer || 0 == readsize)
	    {
	  	  std::string msg = "Get data from file(";
	  	  msg.append(filename).append(") failed!");
	  	  CCLOG("%s", msg.c_str());
	    }
	    else
	    {
	  	  ret.fastSet(buffer, readsize);
	    }
	
	    return ret;
	}
5: 修改unsigned char* FileUtils::getFileData(const std::string& filename, const char* mode, ssize_t *size)为
    unsigned char* FileUtils::getFileData(const std::string& filename, const char* mode, ssize_t *size)
    {
        unsigned char * buffer = nullptr;
        CCASSERT(!filename.empty() && size != nullptr && mode != nullptr, "Invalid parameters.");
        *size = 0;
        do
        {
            // read the file from hardware
            const std::string fullPath = fullPathForFilename(filename);
    #ifdef __XCForwarder_H__
            buffer = XCForwarderLoadData(fullPath.c_str(), mode, size);
    #else
            FILE *fp = fopen(fullPath.c_str(), mode);
            CC_BREAK_IF(!fp);
    
            fseek(fp,0,SEEK_END);
            *size = ftell(fp);
            fseek(fp,0,SEEK_SET);
            buffer = (unsigned char*)malloc(*size);
            *size = fread(buffer,sizeof(unsigned char), *size,fp);
            fclose(fp);
    #endif
            
        } while (0);
        
        if (! buffer)
        {
            std::string msg = "Get data from file(";
            msg.append(filename).append(") failed!");
            
            CCLOG("%s", msg.c_str());
        }
        return buffer;
    }
