Implement loadView in the UIViewController to create a view hierarchy programmatically without a nib file.

- (void)loadView {
    // allocate the subclassed UIView, and set it as the UIViewController's main view
    self.view = [[[UIViewSubclass alloc] initWithFrame:CGRectMake(0, 0, 320, 460)] autorelease];
}

You can continue setting up the view/subview hierarchy in two ways. One is to add them in the custom UIView's initialization method, like so:

// in the MyView.m file
- (id)initWithFrame:(CGRect)f {
    if (self = [super initWithFrame:f]) {
        // add subviews here
    }
    return self;
}

The second way is to continue using the loadView method implemented in the UIViewController subclass, and just using [self.view addSubview:anotherView]. (Alternatively, use the viewDidLoad method in the UIViewController subclass.)

Note: Replace initWithFrame: with whatever the custom UIView's initialization method is (e.g., initWithDelegate:).

Say the view you created is called newView and the controller is newController. The simple approach would be:

newController.view = newView;

But I'd rather subclass UIViewController and override its - (void)loadView and - (void)viewDidLoad methods and create and/or manipulate the view there - that's the way Apple wants you to do it, and for good reason.
