A better option is still to use the UITextField. You don't have to actually show it on screen. Just put it in a 0x0 UIView so that it is not visible, set it's inputView to your UIPickerView and call becomeFirstResponder on it to show the picker and resignFirstResponder to hide it.

It is convenient to have a UIView subclass that implements all of that along with UIPickerViewDelegate and UIPickerViewDataSource methods.
