I have just install Xcode 4.5 and trying to learn new features and tools.
I have set one background image from storyboard and checked whether 'Apply retina 4 factor' and 'Apply retina 3.5 factor' is working fine or not. its working ok.
I have put one UIButton but its not changing its position looks something like this


Can anyone help me in this ?
