If you actually want to push view controllers in the modal view then the modal view needs to be a UINavigationController. So you would do something like this:

ViewController *modalViewController=[[ViewController alloc]initWithNibName:@"ViewController" bundle:nil];
UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:modalViewController];
[modalViewController release];

[self.navigationController presentModalViewController:modalNavController animated:NO];
[modalNavController release];

I generally wouldn't recommend doing it because it is confusing to the user, but in some cases it makes sense.

from the documentation at apple's iphone dev site:

Sets the modalViewController property to the specified view controller. Resizes its view and attaches it to the view hierarchy. The view is animated according to the transition style specified in the modalTransitionStyle property of the controller in the modalViewController parameter.

here are your options if you want to use what Apple gives you:

typedef enum {
   UIModalTransitionStyleCoverVertical = 0,
   UIModalTransitionStyleFlipHorizontal,
   UIModalTransitionStyleCrossDissolve,
} UIModalTransitionStyle;

anything else, and you'll have to do it manually, which isn't too hard. First load your new view in the current or a new view controller. Set it to its initial state, start an animation block, call:

+ (void)beginAnimations:(NSString *)animationID context:(void *)context

do whatever transformations you want then:

+ (void)commitAnimations

I don't believe you can without using undocumented classes. However, if you set the rightBarButtonItem property to an item that looks the same, there shouldn't be a big difference.
