Trying to add a subview, drawRect isn't called

I'm trying to add a subview to my main view. Here's the relevant code from my viewController:

- (void)viewDidLoad {
    [super viewDidLoad];
    MyUIViewSubclass* myView = [[MyUIViewSubclass alloc] init]; 
    [self.view addSubview:myView]; // self.view is a simple UIView
    [myView setNeedsDisplay];
}

drawRect in myView doesn't get called.

However, if I use a MyUIViewSubclass as the main view for the viewController (setting it in Interface Builder), drawRect does get called.

What do I need to do to get drawRect called in my subView?

Ok, figured it out. Wasn't setting the frame of my subView.

In your subclass you should use the designated initialiser for UIView:

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) 
    {
       //Implementation code...
    }
}
