While rebuilding my project with the new Xcode 5 released yesterday, I was disappointed to see my storyboard view controller shaken up.
After many attempts to fix things, I must conclude I'm stuck with one remaining issue: Navigation View Controller makes the navigation bar overlaps with the content of the view. Doing so, the app is ok on a iOS 7 device (no overlapping), but with a iOS 6.1 device, the navbar overlaps.
I ran a sample project from FlatUI to crosscheck the issue, and they have the same issue. Any idea please?
As I said in the comment: in IB (interface builder), you need to go to the "Attribute Inspector" for the view controller, and look at the "Extend Edges" attribute: simply uncheck the "Under Top Bar" flag and you're done.
