How do I add the library to link the OpenGL framework in iPhone SDK?

I am trying to study OpenGL and I have the framework added, but I am getting linker errors. I believe the issue is adding the library to the project for linking and EVERY time I try to add a library, I hunt around for the configur开发者_开发问答ation setting forever. Someone, please give me the simple click-n-go answer!

The linker cannot find the CAEAGLLayer framework to link against.

Add the QuartzCore.framework and the linker will be able to find the missing framework.

To do this right-click on the Frameworks the choose: Add > Existing Frameworks > QuartzCore.framework.
