iOS create UISegmentedControl programmatically

A segmented control is a UI Component that display a series of buttons that are stuck to each other and displayed horizontally. You can relate this to a group of radio buttons on a HTML form where the user can make a choice. In this example we will learn the following
  • Create and initialize a UISegmentControl from an array list of Items
  • Set style for the segmented control
  • Default a specific segment as selected
  • Remove a segment from the control
  • Add a new segment to the control
  • Attach a target action to the control to capture the selection made by the user
  • You can make the control work like a UIButton that pops back up by setting the momentary property to TRUE
