I'm trying to set up a UIPickerView with a UIToolbar on top of it. The two views will be called in response to a user click on the current UITableView that is displayed. I need the picker and toolbar to transition from the bottom (similar to how the picker responds with a combo box in safari). I tried adding a view controller containing the picker view and toolbar as a modal view to the current navigation controller - but just ended up with a white background and a toolbar floating in the middle. Any suggestions on how to get this to work?
