[UPDATE: Oct 9, 2012] OK, the chapter is not so obsolete if you turn off ‘Use Autolayout’ for the view - see the second post below.
After updating to xCode 4.5, the concept of an autosizing inspector shown in Figure 8 appears go be gone. when I select the view or any of the buttons, imageview or horizontal slider post xCode 4.5 upgrade there is no longer an autosizing size inspector in the ‘Show the Size Inspector’ tab.
There appears to be a whole new paradigm for dealing with what happens when views rotate. Each time I added a subview to the main view new ‘Constraints’ shows up with purple icons in the Objects window. It appears that through these the developer is to control what happens when a view is rotated. I spent a few minutes with them but couldn’t find any obvious way to replicate what was going on in the remainder of chapter 8. When i run the Heavy Rotation App the image view doesn’t re-size. It scrolls past the end of the page and the buttons underneath are gone. My slider does stay at the top and adjust to be the full width of the landscape screen.
It would seem that I need to add a new vertical constraint somehow to make sure the image view stays centered above the bottom. But i can’t see how toa dd a new constraint beyond those created automatically.
I know that the authors just put out an update to the changed book page in .pdf form:
but the issues arising from these changes are not dealt with there.
I would post images on the changes but near as I can tell there is no way to upload images to this forum.
Onwards to Chapter 9 I guess.
