1、下载源代码。http://download.youkuaiyun.com/detail/ouyangtianhan/85737532、brew install cmake3、各种 sudo chmod 7774、brew link cmake5、cd 到 platform 下到 ios，python build_framework.py iOS。将会在iOS下生成各种架构的framewor

Error 1:当我在程序中调用 glDrawArrays(GL_TRIANGLES,0, 3 * o.numTriangles);我check到 0x0505 即 out of memory 到 OpenGL error。No ideas for now :(PS 1:I found sometimes glDrawElem
