How to make Modal view over Tab Bar instead of under?

I have a tab bar to select one of four different screens. For one of the views, let's call it "view A" I also have a modal view that slides up. This all worked fine and the modal view slid up over the tab bar which is what I want. I wanted to add a flipside view to "view A". In order to do this I made a rootviewcontroller to control "view a" and the flipside and toggle between them. Well this broke the modal view. So I then moved the modal view code that was in "view a"'s controller code to the root view controller code that I added to have the flipside animation. This is almost working, but the problem is now the modal view slides under the tab Bar instead of over it. How do I control this? The other problem is that when I dismiss the modal view, the button that allows the modal view to be presented in "view a" disappears. So I assume the button is getting pushed to the back. Here is my code for presenting the modal view controller over "view a". I think I may have some extra stuff in here I don't need.

- (IBAction)activatetradeinview:(id)sender {
//change view
LeaseViewController *timodal= [[til alloc] initWithNibName:@"tilxib" bundle:nil];
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:timodal];
 LVController *viewController = [[LVController alloc] initWithNibName:@"LView" bundle:nil];
self.lViewController = viewController;
 [viewController release];
 
[self.view insertSubview:lViewController.view aboveSubview:infoButton];
[lViewController presentModalViewController:secondNavigationController animated:YES];
 [timodal release];
 [secondNavigationController release];
}
