Add a UIview to an UIViewController

Question

I'm a beginner in Iphone development. I have a project with a single openGL View.

I already wrote an UIView Controller class. but I don't know how to add the view to the UIViewController, and how to integrate the UIViewController to the project. Also, I don't know

Any help, similar example, or link to a tutorial is very appreciated. Thanks.

Answer 1

UIViewController has a "view" property. If you want your openGL View to be the base view for the controller you would assign it like so.

myViewController.view=myOpenGLView;

If you want the openGL view to be a subview of the controllers main view you would assign it thusly:

[myViewController.view addSubview:myOpenGLView];

The important thing to remember is that the view controller is not itself a view. To add and remove views or to refer to views you use the controller's view property. UIView has the methods specifically for managing the view hierarchy.
