You can use like this too.

For adding:

[[UIApplication sharedApplication].keyWindow.rootViewController addChildViewController:childVC];
[[UIApplication sharedApplication].keyWindow.rootViewController.view addSubview:childVC.view];

For removing:

[childVC.view removeFromSuperview];
[childVC removeFromParentViewController];
