UISegmentedControl includes API for customizing it's appearance. You set images for various state combinations using -setBackgroundImage:forState:barMetrics: and -setDividerImage:forLeftSegmentState:rightSegmentState:barMetrics:.

You can also customize the text using -setTitleTextAttributes:forState:.

These methods can be found in the Customizing Appearance section of the UISegmentedControl documentation.
