iphone popup how to? what control to use

I want to make a popup type of layer on the iPhone 4. Is that possi开发者_StackOverflow社区ble? Like in this screenshot:

On the iPad, you can use the built in UIPopoverController to achieve a very similar control. There is no built in control that shows like a popover in the iPhone. You will either have to create your own or use a different control.

There is an open source Popover for iPhone. I've never used it but I think it will fulfil your needs: https://github.com/werner77/WEPopover

That’s a custom control. There’s a system pop-up control on the iPad called UIPopOverController, but I don’t think it’s available on the iPhone. See also this previous question about popovers on iPhone.
