iOS: Access app-info.plist variables in code

I am working on a Universal app & would like to access the values stored in app-info.plist file in my code.

Reason: I instantiate a UIViewController dynamically from a storyboard using:

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
self = [storyboard instantiateViewControllerWithIdentifier:@"ExampleViewController"];

Now, having the storyboard name @"MainStoryboard_iPhone" above is ugly.

I want to do something like:

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:appInfo.mainStoryboardBaseNamePhone bundle:nil];
self = [storyboard instantiateViewControllerWithIdentifier:@"ExampleViewController"];

where appInfo can perhaps be an NSDictionary of all values in app-info.plist
