only show half screen of controller using presentModalViewController

Question

i have a UIViewController that is only about 260px tall(or at least the area i want viewable is 260 approx. height) and really just has a picker on it and a done button. I'm calling presentModalViewController to display it but its showing the whole view, when really i only want to show the picker and the done button bar above the picker, not the black above the bar , is there a way to show only this and not the whole view behind the picker when it is presented ?

not too much for code here, ....

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:tipPickerController];

[self presentModalViewController:navigationController animated:YES];

let me know if i should post more code to get help, thanks

Direct answer to your question:
You don't have to use a full screen view (320 X 480). You might set the view for the exact size that you need (without the black part on the top).

My suggestion:
Set the view for full screen, but in addition set a transparent color for your top level view (instead of black).
This way the original view won't be interactive while the picker is visible...
