Please tell me there is a way to make a variable open for any class in the program to use because i can not figure out how to get the drawView class to recognize variables i declared in App Delegate. it is because i am initiating some variables in applicationDidFinishLaunching. (OpenGL ES template under new project).
Got a tip for us?

You can use standard C conventions for declaring, instantiating and using global variables outside your Cocoa object declarations. Read any complete generic C tutorial. Be aware of the pitfalls of using global variables in large or reusable code projects.

I'm not sure how to use [[UIApplication sharedInstance] delegate] properly. Is there online documentation available?
I decided to access those variables with methods, but for other classes to access those methods, they have to be in protocols right? Can someone show me how to implement a protocol or point me in the right direction?
