1：please run at terminal:
注意IOSVER和SIMVER必须和自己实际环境一致

2: please add libluajit2.a into ios project.
The libluajit2.a is in LuaJIT2.0.0/build folder.
3: The luajit header files:
mkdir -p $BUILD_DIR/Headers cp $LUAJIT/src/lua.h $BUILD_DIR/Headers cp $LUAJIT/src/lauxlib.h $BUILD_DIR/Headers cp $LUAJIT/src/lualib.h $BUILD_DIR/Headers cp $LUAJIT/src/luajit.h $BUILD_DIR/Headers cp $LUAJIT/src/lua.hpp $BUILD_DIR/Headers cp $LUAJIT/src/luaconf.h $BUILD_DIR/Headers
4:效果
luajit在IOS只对解释器进行了优化，编译器由于权限问题，不能运行。从我测试结果来看，使用luajit后效果还是比较明显的，对比测试可以明显感觉到速度变快了
