I'm trying to use a UIPickerView and for some reason, even though I have the required methods implemented in my code, I have it as an outlet and hooked up to the File's Owner of the view, along with that view controller being the datasource and delegate, my application no longer opens on the simulator. However, when I delete the UIPickerView from IB, the app opens fine so I am assuming it is a problem with the UIPickerView. I can't find what is wrong. Has anyone come across something similar or other things I should check for? Thanks.
