    [_window release];
    [_viewController release];
    [super dealloc];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease];
    } else {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil] autorelease];
    }
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

@interface ViewController ()

@end

Parts of the framework are retaining and releasing (or autoreleasing) the object as they feel appropriate. This is one of the many reasons why you are encouraged not to try to track retain counts precisely — you don't need to know all these retains and releases are happening, as they have nothing to do with you.

Most likely, your view controller is being added to autorelease pools as it is handed around through system libraries. But as long as you're confident that your code is managing the view controller correctly, you should just ignore this as background noise.
