Trying to mimic the Apple iPad popover style

My sincere apologies if this question has been asked, but I really couldn't find it.

Essentially, I am trying to mimic the look of the popovers used by the built-in Apple applications. In particular, not the popovers that use a tableview list, but rather those popovers that only have buttons inside.

For example, in the Mail app, clicking the left-facing arrow on the top right of the screen, a popover is shown with four buttons: Reply, Reply All, Forward开发者_JS百科, Print.

How is this particular popup created to give that look?

I have tried making my own UIViewController with a black background and Round Rect Buttons, but it doesn't look the same. Any help would be much appreciated!

Thank you.

It's a UIActionSheet. On iPad, it gets a "popover" appearance if it's not presented from within another popover.
