Objective-c – Dark shadow on navigation bar during segue transition after upgrading to Xcode 5.1 and iOS 7.1

Behavior from some of the properties of UINavigationBar has changed from iOS 7. You can see in the image shown below :

Two beautiful links I'd like to share with you. For more details you can go through these links :

1. iOS 7 UI Transition Guide.
2. How to Update Your App for iOS 7.

Apple Documentation for barTintColor says :

This color is made translucent by default unless you set the translucent property to NO.

Sample Code :

self.navigationController.navigationBar.barTintColor = [UIColor blackColor];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
[self.navigationController.navigationBar 
 setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
self.navigationController.navigationBar.translucent = NO;

I solved this problem by myself through following way:

MyChildViewController *childViewController = [[MyChildViewController alloc] initWithNibName:@"MyChildViewController" bundle:nil];
[childViewController.view setFrame:CGRectMake(0.0f, 0.0f, self.rightContainerView.frame.size.width, self.rightContainerView.frame.size.height)];

UINavigationController *childNavController = [[UINavigationController alloc] initWithRootViewController:childViewController];
childNavController.view.frame = childViewController.view.frame;

[self addChildViewController:childNavController];
[self.rightContainerView addSubview:childNavController.view];
[childNavController didMoveToParentViewController:self];

Now when I add navigation bar in MyChildViewController, it gets added in child view controller and does not affect navigation bar of parent view controller. The navigationController property of child view controller is also different than navigationController property of parent view controller and both have their own navigation stacks.
