UIScreen bounds versus applicationFrame

Question
Why do I see in some sample code from Apple (such as PhotoScroller) that I should do the following in loadView
:
CGRect frame = [[UIScreen mainScreen] bounds];
instead of
CGRect frame = [[UIScreen mainScreen] applicationFrame];
Does it make a difference to get the main screen's frame?
Solution
ApplicationFrame is the screen size minus the size of the status bar (if visible), bounds is the screen size regardless of status bar.
So applicationFrame would return CGRectMake(0,0,320,460)
assuming your app has the status bar set to be visible, while bounds would return CGRectMake(0,0,320,480)
under the same conditions. Those numbers are assuming iPhone/iPod Touch screen sizes.

iOS 9 Update
When using the Split View feature on the iPad, applicationFrame
returns the size of your app window. bounds
always returns the size of the device.
