Picker View Help

I have a Login Screen with 5 Fields. Currently, all fields prompt the keyboard as the first responder, as is normal. What I would like is for 4 of these fields to prompt the keyboard as it currently stands when the text fields are clicked, but for 1 of the fields to dismiss the keyboard and show a picker view in its place.

All the picker view tutorials I have seen treat the PV as a static object that just sits on a View Controller altering a label, without the means to dismiss it, or to program it so that the PV only appears in a view when a text field is clicked.

Can anyone point me in this direction? Do I just plop a PV down on the storyboard and then dismiss it programatically in viewWillAppear or something? Then prompt it again when the text view is clicked. Will there be a conflict when the Keyboard is present and the picker view is called?

If anyone has thoughts on this or can point me to a resource I would appreciate it.

Thanks!

I havent worked with a picker view before, but this could work:

you could plop it down in your storyboard then in viewWIllAppear hide it using 

self.picker.hidden = YES;

then when the text field/label/whatever you use is pressed (you could use an action for this, or a delegate method if it has one) 

self.picker.hidden = NO;

if there is a conflict with the keyboard and the picker view you could dismiss it when the picker view appears then bring it back up when the picker view is hidden again I guess. Couldnt really tell you much about that
