At the end of the chapter, there are instructions about changing the width constraint of the UIImageView to a placeholder using the attributes inspector. In Xcode 5.1, I can’t find the UI element for enabling this. What am I missing?
I still see it under the Attributes Inspector. Make sure the constraint is selected, and then you should see it at the bottom. Here is a screenshot from Xcode 5.1 with a constraint selected: cl.ly/image/2F0U201O1I2W
Thanks for the sanity check. It turns out the little constraints attributes inspector widget was collapsed and so only showed the title. I didn’t realise you could even collapse these widgets and I was mostly confused by the fact that it was only collapsed for the constraints and not for anything else that I selected.
