Answer 1

Apple calls it a "Picker" in its iOS Human interface guidelines.

Picker

A picker displays a set of values from which a user picks one.

To learn more about defining a picker in your code, see UIPickerView Class Reference. Appearance and Behavior

A picker is a generic version of the date and time picker. As with a date and time picker, users spin the wheel (or wheels) of a picker until the value they want appears. The overall size of a picker, including its background, is fixed at the same size as the keyboard on iPhone. (For more information about the date and time picker, see “Date and Time Picker.”)

Answer 2

On Android, you can use a Spinner or a NumberPicker. The latter is available as of Android 3.0 and can be used for more than just numbers.
