I have transitioned my iPad application from iOS 6 to iOS 7 and I had to turn off auto layout or the whole application would crash when I selected to view the storyboard.
Now that I can view it, all the uielements don't appear in the each storyboard screen.
The screens are there but they are blank (white). The editor shows that they are there but I cannot view them at all.
Try changing the width and height/ x and y coordinate of the views. That fixed the same problem for me.
