I'm not sure if this the intended behavior of the segmented control, but when I place the object in a view that is embedded in a Navigation Controller, the segment titles don't show up. I discovered that if I scrolled up within the area where the title should be, the titles eventually showed up, so it seems that the titles are being incorrectly positioned.
I also tried embedding a UIView inside a container view, but I still had the same issue.
Any ideas?
