RSDMassInputTableItem

public final class RSDMassInputTableItem : RSDTextInputTableItem

A custom implementation for inputing a person’s mass (weight) that can set up a picker for setting the weight of an infant. Typically, US participants know what their newborn baby’s weight is in lb and oz. Additionally, the placeholder text for an adult or child measurement range will be either pounds or kilograms, depending upon the participant’s locale.

  • The base unit is the unit of mass that the measurement should be converted to in order to save the result. Because the Measurement class has a generic UnitType, it cannot be easily converted to a Codable object so the results are stored as .decimal base type with the unit symbol also stored on the result.

    Declaration

    Swift

    public let baseUnit: UnitMass

  • Default initializer.

    Declaration

    Swift

    public init(rowIndex: Int, inputField: RSDInputField, uiHint: RSDFormUIHint, measurementSize: RSDFormDataType.MeasurementRange)

    Parameters

    rowIndex

    The index of this item relative to all rows in the section in which this item resides.
    inputField

    The RSDInputField representing this tableItem.
    uiHint

    The UI hint for this row of the table.
    measurementSize

    The measurement range for the input field.

  • Override the convertAnswer() function to convert the Measurement returned by the formatter into a decimal value in the baseUnit.

    Declaration

    Swift

    override public func convertAnswer(_ newValue: Any) throws -> Any?
