顶点着色器'v_gradient'的输出未被片段着色器读取 [英] Output of vertex shader 'v_gradient' not read by fragment shader

问题描述

当我在ios 10设备和xcode 8上运行我的应用程序时，我在调试控制台中收到以下消息。任何人都可以知道为什么会这样吗

When i run my app on ios 10 device and xcode 8 i'm getting the following message in debug console. Can any one know why this is happening

推荐答案

该错误与模拟器的渲染方法有关。框架，而不是真实设备的框架。

The error is related to the Simulator's rendering methods & framework, as opposed to those of a real device.

问题不应在真实设备上重现。
