The ORKValuePickerAnswerFormat class represents an answer format that lets participants use a value picker to choose from a fixed set of text choices.

When the number of choices is relatively large and the text that describes each choice is short, you might want to use the value picker answer format instead of the text choice answer format (ORKTextChoiceAnswerFormat). When the text that describes each choice is long, or there are only a very small number of choices, it’s usually better to use the text choice answer format.

Note that the value picker answer format reports itself as being of the single choice question type. The value picker answer format produces an ORKChoiceQuestionResult object.
