A designer asked me to add pagination to a UINavigation bar in a project with its target building for ios4.3+.
I know you can add two buttons to the right side of a Navigation bar as explained here in this blog : enter link description here
But to get the appearance requested to by the designer

Do I need to add images to my button or is this some kind of native control(Special UISegmentedControl?) I haven’t seen before? Or Just 2 custom buttons with background images.
Thanks,
-Code
I implemented the same function with a segmented control and without defining custom buttons with images.Instead of adding images for arrows i used the the corresponding Unicode chars and instantiated the segmented control with them.
Then your leftBarButtonItem is replaced by the segmented control.
