Does this segue still exist in iOS9?

Question

I seem to recall a few years back that Apple Maps had a segue that would roll back the map from the bottom right corner to reveal options such as 2D/3D, add traffic conditions etc. But the map was still partially visible.

Does this segue still exist? I'm presenting information about various beers... ABV for example.. but there are many others. I want to add an information button that will present the definition of (Alcohol By Volume) without transitioning abruptly to completely different View.

You may use the following animation for subView UIViewAnimationTransitionCurlUp. Here is the sample code:

[UIView beginAnimations:@"PartialPageCurlEffect" context:nil];
[UIView setAnimationDuration:0.3];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:myOldSubViewController.view cache:YES];
[myOldSubViewController.view addSubview:myNewViewController.view];
[UIView commitAnimations];
