Problem with uiscrollview swapping in iOS 6 using storyboard

I have a very strange problem. I use this tutorial: http://www.iosdevnotes.com/2011/03/uiscrollview-paging/ to do the swap uiscrollview. But it seems that I do not work in iOS 6 when I try to implement it in a storyboard. I just copied the code and took all the necessary steps. But that still doesn't work. uiscrollviewjust refuses to show anything. But the fact is, it worked great before I upgraded my Xcode to the latest version. Can anyone suggest what I'm doing wrong? Maybe I forgot something?
