cocos CCLayer glDrawArrays(GL_TRIANGLE_STRIP, 0, 4);ios11闪退 spine动画

搜索一下方法，找到后替换不同内容：

void PolygonBatch::flush () {
 if (!_verticesCount) return;
 
 GL::bindTexture2D(_texture->getName());
 
    //ios11闪退修改测试
//    GL::bindVAO(0);
//    glEnableVertexAttribArray(GLProgram::VERTEX_ATTRIB_POSITION);
//    glEnableVertexAttribArray(GLProgram::VERTEX_ATTRIB_COLOR);
//    glEnableVertexAttribArray(GLProgram::VERTEX_ATTRIB_TEX_COORDS);
 
    GL::enableVertexAttribs(GL::VERTEX_ATTRIB_FLAG_POSITION | GL::VERTEX_ATTRIB_FLAG_COLOR | GL::VERTEX_ATTRIB_FLAG_TEX_COORD);
