I need a UIDatePicker for selecting Month and Year only. I checked the class reference documents. Looks like UIDatePicker is a UIView.
No, this cannot be done using the stock UIDatePicker.
UIDatePickerModeDate
The date picker displays months, days of the month, and years. The exact order of these items depends on the locale setting. An example of this mode is [ November | 15 | 2007 ].

I recommend customizing a UIPickerView to use two components and populating its rows with month and year symbols retrieved from NSDateFormatter.
