I've added three new projects to my
iOS OpenGL ES repository on GitHub. They are fairly simple examples of how to use
GLKit and
GLKBaseEffect. You can find them in the
GLKit Stuff directory.
They're kind of rough, but they should be helpful to you if you're just getting started with GLKit and trying to figure out how to use it.
Thanks to
Julián Oliver for tweeting the solution to a problem I was having getting textures to work with
GLKBaseEffect.
