问题
I have a UISegmentedControl that is being displayed within my UINavigationBar on an iPhone app running iOS 7. I've noticed that when I select one of the values in the UISegmentedControl the highlighting does not stay active. That is, if I select the first item, it triggers the action that I have added to it, but immediately un-highlights the value I selected.
Is this expected behavior? A bug? I don't recall ever seeing this in other apps using this control, and it works just fine on iOS 6. Thoughts?

Make sure the momentary property of the UISegmentedControl is NO (Apple docs).
