Question

在iOS上工作得很好，但在可行的情况下却没有，也许我做错了什么：

    GLsizei height = _glview.drawableHeight;
    GLsizei width = _glview.drawableWidth;

    if (pickingFramebuffer == 0) {
        glGenFramebuffers(1, &pickingFramebuffer);
    }

    glBindFramebuffer(GL_FRAMEBUFFER, pickingFramebuffer);

    if (pickingColorRenderbuffer == 0) {
        glGenRenderbuffers(1, &pickingColorRenderbuffer);
    }
    glBindRenderbuffer(GL_RENDERBUFFER, pickingColorRenderbuffer);

    glRenderbufferStorage(GL_RENDERBUFFER, GL_RGBA8, width, height);
    glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, pickingColorRenderbuffer);

    if (pickingDepthRenderbuffer == 0) {
        glGenRenderbuffers(1, &pickingDepthRenderbuffer);
    }
    glBindRenderbuffer(GL_RENDERBUFFER, pickingDepthRenderbuffer);
    glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT24, width, height);

    glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, pickingDepthRenderbuffer);

    GLenum status = glCheckFramebufferStatus(GL_FRAMEBUFFER);
    if (status != GL_FRAMEBUFFER_COMPLETE) {
        NSLog(@"Framebuffer status: %x", (int)status);
    }

日志：

Framebuffer status: GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT

非常感谢！

修改如果我将添加到everyone函数和opengl指令OES，则Framebuffer状态将为 0

编辑2：好的，这是一个错误https://code.google.com/p/apportable/issues/detail?id=3

我创建渲染缓冲区的代码在Apportable SDK上不起作用
