Autoresizingmask not showing in Interface Builder?

Question

I want to deal with autoresizingmasks, but for some reason I cannot make the dialog appear. The size inspector of my IB is as follows:

When I click on another inspector - attributes, connections, etc. - the dialog / inspector autoresizingmasks appears for a moment (not enough for me to take a screenshot), only to be replaced by any inspector, you clicked. I assume that I have some kind of tweak or other function that I need to get tuned up, but the Xcode firmware did not detect it and I did not find this problem in other Xcode issues. Obviously a very simple question, but can anyone help?

Answer 1

File Inspector → Document Builder Document → Use Autolayout [UNCHECK]

Autolayout is a new feature of OSX7 / iOS6 using restrictions (as you can see from this inspector)
- it replaces Autoresizing masks, but only works on OSX7 + and iOS6 +
