Memory Leak with Navigation Controller

[NJ1]

This is a very simple test code to debug a very mystifying leak. When I run this code using Xcode's leak tool I get two leak objects ( _NSArrayM). The commented line below shows my leak source but I just fail to understand why I get this leak. All allocs in this code have been properly released.
Only way I can get rid of the leak is if I build my viewcontrollers using Interface Builder.
Any clue will be greatly appreciated. I am sure I am missing something very simple here. Anybody any ideas??

P.S using SDK 4.0

- (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions {

// Override point for customization after application launch.

UIViewController *VC1 = [[UITableViewController alloc]initWithStyle:UITableViewStylePlain];
VC1.title =@"First";
UINavigationController *nvc1 =[[UINavigationController alloc]init];
[nvc1 initWithRootViewController:VC1]; // Source of LEAK 1 !!!


UIViewController *VC2 = [[UITableViewController alloc]initWithStyle:UITableViewStylePlain];
VC2.title =@"Second";
UINavigationController *nvc2 =[[UINavigationController alloc]init];
[nvc2 initWithRootViewController:VC2]; // Source of LEAK 2 !!!

// Add the tab bar controller's view to the window and display.

tabBarController.viewControllers = [NSArray arrayWithObjects:nvc1,nvc2, nil];


[nvc1 release];
[nvc2 release];
[VC1 release];
[VC2 release];

// Add the tab bar controller's view to the window and display.
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];

return YES;
}

you are initializing 2 times, so you have the leak. Just do_

UINavigationController *nvc1 =[[UINavigationController alloc]initWithRootViewController:VC1];

and same for the 2nd

Thanks! That was a easy fix! Moral of the story here: never rely only on balancing allocs/retains/releases.
