Interface Builder Send to Back

UI Builder 'send to back' can be done by:

Toolbar->Layout->Send to back

Toolbar disappears on rotate (ipad/iphone/ios)

In interface viewer, my toolbar was disappearing when I rotated the interface.

To solve it, I had to adjust the 'Autosizing' property inside the 'Toolbar Size' tab.

"does not have an outlet named" problem in XCode/Interface Builder

I was getting the error "Blah blah does not have an outlet named blahblah" in Interface Builder.

After clicking on 'reload all class files'

I guess the problem was caused because I moved my user directory from one drive to another.

To solve it, I clicked on "File -> Read Class Files" then located the correct view controller class that I was trying to link to.
