iPhone SDK中的弹出菜单？

Question

I'm designing a tab-based app, and I want a menu to pop up from one of the tabs when the user taps it. Like in the WaveSense Diabetes Manager app (I would post pictures, but I'm a new user and SO won't allow it. It's a free download if you would like to check it out; it has a cool design that you can take some ideas from).

Tapping a tab bar icon brings up a little pop-up menu, as opposed to switching the UIViewController. I've looked everywhere and have no idea how make something like this. I'm guessing modifications have to be made to the UITabBarController? Is the pop-up menu a custom UIView? Please help!

Thanks!

Answer 1

The tab bar delegate has a method tabBar:didSelectItem: . You could render your menu at that time, animating it up from the tabBar if you wanted.

As far as creating the menu, a UIView with a UITableView contained in it would work great. You can make the view smaller than the width of the device screen if you like, to get the effect of it being a menu which slides up. It would also allow you to have more menu entries than would comfortably fit on the screen.
