Am working on an ipod/iphone application that primarily captures a photo. Am designing the flow in xcode4 IB storyboard. 
However, as you can see from the image it is taking the default resolution as 320×480 which causing the preview on ipod retina display to show up in a corner than full screen. How can I make the IB get device resolution and adjust the ratio accordingly?
I tried looking at project settings, build settings, info.plist however couldn’t find an answer yet.
Thx
Those dimensions are in points, not pixels. They are correct. On retina displays, 320 points are equal to 640 pixels. If your application is only showing up in a quarter of the screen, it’s likely the problem is in your code, not in how you have set things up in Interface Builder.
