I am learning iOS and using Apress - Beggining iOS 5 development book. The book says there is a window to preview UI elements's autosizing behaviour in size inspector as:
but I can not see such a window. After searching in Xcode windows I realized that that windows actually appearing in a very short time period while switching size inspector to any other section in utilities tab. How can I make it constanly appear?
I have found the answer here
Xcode 4.3 not presenting Autoresizing panel in Size Inspector Just uncheck "Use Auto Layout" option on file inspector tab:
While you are editing XIB or storyboard file. You can see "Size Inspector" tab panel at right menu. It has a ruler icon.
But the view -that you want to set it's layout- must be selected. At this sample on screenshot, a Label (text:social) is selected.
This tutorial can help to your problem.
