ios - iPhone application - pop up dialogue - sort of -

i have iphone application is, in essence, list. there uinavigationbar @ top, , there uitableview holds list. i'd have option in way or of allowing user sort list in different ways. so, in mind, picture having navigationitem on uinavigationbar that, when touched, little pop dialogue comes up. select "sort" want, check mark appears next it, , dialogue goes away.

i'm not sure how this. tried creating uiview, adding uiviewcontroller onto (which held list of different "sort" parameters (ex. sort alphabetically, sort date, etc) in uitableview. but uitableview isn't responding touches, , i'm not sure why.

does have idea using apples wonderful interface having option this? can't use uisegmentedcontrol below uinavigationbar, because there 5 possible options, , can't fit in single uisegmentedcontrol.

thanks!!

this sounds job uipickerview. slide 1 bottom of view whenever button pressed. i've done in past , works well. perhaps this article can started. hope helps!
