cocos2d-x 2.2.6 之 split分割字符串

如果有这样的数据，如： “100#200#300#400”，在之前使用orge引擎的情况下，可借助split来实现，如：

Ogre::String str = "100#200#300#400";
StringVector strVec = StringUtil::split(str,"#");

其实现代码如下，在OgreString.cpp中：

// 头文件
static vector<String>::type split( const String& str, const String& delims = "\t\n ", unsigned int maxSplits = 0);

// 实现文件
StringVector StringUtil::split( const String& str, const String& delims, unsigned int maxSplits)
    {
        StringVector ret;
        // Pre-allocate some space for performance
        ret.reserve(maxSplits ? maxSplits+1 : 10);    // 10 is guessed capacity for most case

        unsigned int numSplits = 0;

        // Use STL methods 
        size_t start, pos;
        start = 0;
        do 
        {
            pos = str.find_first_of(delims, start);
            if (pos == start)
            {
                // Do nothing
                start = pos + 1;
            }
            else if (pos == String::npos || (maxSplits && numSplits == maxSplits))
            {
                // Copy the rest of the string
                ret.push_back( str.substr(start) );
                break;
            }
            else
            {
                // Copy up to delimiter
                ret.push_back( str.substr(start, pos - start) );
                start = pos + 1;
            }
            // parse up to next real data
            start = str.find_first_not_of(delims, start);
            ++numSplits;

        } while (pos != String::npos);
        return ret;
    }

 那么cocos2d-x 中有类似的函数存在吗？很幸运还是找到了，大家可参考：...\cocoa\CCNS.cpp，其实现代码如下：

#include "CCNS.h"          // 

typedef std::vector<std::string> strArray;
// string toolkit
static inline void split(std::string src, const char* token, strArray& vect)
{
    int nend=0;
    int nbegin=0;
    while(nend != -1)
    {
        nend = src.find(token, nbegin);
        if(nend == -1)
            vect.push_back(src.substr(nbegin, src.length()-nbegin));
        else
            vect.push_back(src.substr(nbegin, nend-nbegin));
        nbegin = nend + strlen(token);
    }
}
