我在这里按照jeff的教程讲解了iP​​hone OS中的hud显示 http://iphonedevelopment.blogspot.com/2010/02/drawing-hud-display-in-opengl-es.html 该示例将以等面体作为HUD的背景，用于伴随的项目，并且按预期的方式使用颜色和文本.

但是，当我将代码复制到带有他的教程系列之一的带纹理对象的修改的项目中时，该教程系列与此

But when I copied the code into my modified project with the textured objects from one of his tutorial series on this one http://iphonedevelopment.blogspot.com/2009/05/opengl-es-from-ground-up-part-6_25.html, I see that the HUD display has no colors no matter how I change the color settings.
