addChildViewController view not displaying

Using storyboards I am trying to overlay a UIViewController on top of a current View.

In my FirstViewController I import the SecondViewController.h and then run the following in the viewDidLoad method

SecondViewController *overlay = [[SecondViewController alloc]init];
overlay.view.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height);
[self addChildViewController:overlay];
[self.view addSubview:overlay.view];
[overlay didMoveToParentViewController:self];
[self.view bringSubviewToFront:overlay.view];

In my SecondViewController.h viewDidLoad method I have an output to NSLog which is getting displayed in the console when I run the app, however the second view is not being display on top of the first. So the SecondViewController is getting added but not displayed. What is it am I missing?

Essentially I want the SecondViewController to have transparent background so I can do a fancy alert message that displays information, and you can still see the FirstViewController behind it.

Thanks

First set the identifier of secondViewController and the use the simple code:

secondViewController *overlay = [self.storyboard instantiateViewControllerWithIdentifier:@"secondViewController"];
overlay.view.frame = CGRectMake(100, 100, 100, 200);
[self.view addSubview:overlay.view];

In my case the identifier is same as class name that is "secondViewController".
