Status bar and navigation bar appear over my view's bounds in iOS 7

Question

I recently downloaded Xcode 5 DP to test my apps in iOS 7. The first thing I noticed and confirmed is that my view\'s bounds is not always resized to account for the status

You don't have to calculate how far to shift everything down, there's a build in property for this. In Interface Builder, highlight your view controller, and then navigate to the attributes inspector. Here you'll see some check boxes next to the words "Extend Edges". As you can see, in the first screenshot, the default selection is for content to appear under top and bottom bars, but not under opaque bars, which is why setting the bar style to not translucent worked for you.

As you can somewhat see in the first screenshot, there are two UI elements hiding below the navigation bar. (I've enabled wireframes in IB to illustrate this) These elements, a UIButton and a UISegmentedControl both have their "y" origin set to zero, and the view controller is set to allow content below the top bar.

This second screenshot shows what happens when you deselect the "Under Top Bars" check box. As you can see, the view controllers view has been shifted down appropriately for its y origin to be right underneath the navigation bar.

This can also be accomplished programmatically through the usage of -[UIViewController edgesForExtendedLayout]. Here's a link to the class reference for edgeForExtendedLayout, and for UIRectEdge

[self setEdgesForExtendedLayout:UIRectEdgeNone];
