| Declared in | ORKAnswerFormat.h |
The ORKMultipleValuePickerAnswerFormat class represents an answer format that lets participants use a
multiple-component value picker to choose from a fixed set of text choices.
Note that the multiple value picker answer format reports itself as being of the multiple picker question
type. The multiple-component value picker answer format produces an ORKMultipleComponentQuestionResult
object where the index into the array matches the array of ORKValuePickerAnswerFormat objects.
For example, if the picker shows two columns with choices of [[A, B, C], [1, 2, 3, 4]] and the user picked
B and 3 then this would result in componentsAnswer = [B, 3].
