Initial Description

The UISegmentedControl consists of a horizontal control divided into segments. Segmented controls are useful for allowing users to pick from a group or set of values.

Each segment functions as its own button. By default, selecting a segment will deselect the others in the control (much as a radio button does in HTML). You can alter this behavior by setting the "momentary" property.
