The best option is to use the top layout guide (topLayoutGuide). This will tell you where to place your subviews, based on the presence and size of the status bar, navigation bar, whether the view extends below them, etc.

Ideally, you should use auto-layout. Then just add a constraint from the view's top to the top layout guide (in Interface Builder, control-drag from the view to the superview and select "Vertical Spacing to Top Layout Guide").

Don't forget the status bar can change size (during a call and other similar circumstances). With auto-layout, this will be taken care of for you automatically.

That's known as the status bar. Off the top of my head I think you can find the frame for it using 

[UIApplication sharedApplication].statusbarFrame
