A nice segmented control for iOS ###Usage:
(see sample Xcode project in /SRVSegmentedControlDemo)
SRVSegmentedControl is a more customizable option to the standard UISegmentedControl. It supports and arbitrary number of items, and can either be set up in IB or programmatically. It emits an event for UIControlEventValueChanged whenever a different segment is selected. It's really pretty straightforward.
