Ok this is probably so simple that it's laughable, but I can't figure the answer. What is the property of the uipickerview? For the UIDatePicker, its datePicker.date, for label you can do label.text, etc etc. Is there a pickerView.XX syntax where I can get the value selected similar to the datePicker? Please let me know. Thanks ...

However, when I delete the UIPicke...

Basically, I want the functionality of the UIDatePicker when it scrolls the hours/minutes/seconds continuously.

Is it possible for a UIPickerView to appear instead of a keyboard when a UITextField is selected? Every option in Interface Builder is some sort of keyboard.

I'm new to iPhone and Objective C programming but I'm able to make my code work. I'm just not sure if it's the best way to do it because it requires a lot of code and doesn't look pretty.
