what type of view controller is this?

Question

and how do you create it? - the popup one in the middle

I would lie to use something like this for my game (in the main menu).

Answer 1

There is no type for UIViewController . There are different ways how you can present UIViewController .

iPad support following three type:

1. Full Screen
2. Page Sheet
3. From Sheet

Your image is showing third one UIModalPresentationFormSheet .

You can Find detail of how to use this three type of presentation at following app guide: Presenting View Controllers from Other View Controllers .

Answer 2

That's the link to the documentation.

Presenting View Controllers from Other View Controllers

A modal view controller is a controller that can be presented on top of another one.

To create it, for example, you can just call presentViewController:animated:completion: method of the current view controller, passing in the view controller you want to present.

Since the interface you have uploaded contains a navigation bar that contains a close bar button item, you can simply wrap the controller you want to present in a navigation controller.

YourViewController *yourViewController = [[YourViewController alloc] init];

UINavigationController *navigationController = [[UINavigationController alloc]
                             initWithRootViewController:yourViewController];
[self presentViewController:navigationController animated:YES completion: nil];

Otherwise, you can create a plain controller and use a UIToolBar .

Hope that helps.

PS The close button will not be there for free. You need to add it ;)

Answer 3

I think it would be much better to use a third party library instead of implementing it. There are many libraries that offer similar functionality.

• UAModalPanel

  MTPopupWindow

  KGModal

If you do not want to use the above libraries, you can use UIModalPresentationFormSheet explained by Apple in this document: Presenting View Controllers from Other View Controllers

Hope this helps!
