Xcode being the vast IDE that it is, it’s sometimes the simplest things that flummox you. It’s rare that I ever want to look at the XML code for any of my interface files, unless I’m copying one from one project to another or hunting down some forgotten outlet that’s throwing a warning. But when I do, I invariably forget how to get back to IB view.
If that’s you, fortunately it’s easy to return to the Interface Builder view from the source code view. Just right-click (aka ‘Control click’) on your nib file in the project navigator sidebar and choose “Open as…” and “Interface Builder XIB Document”. Unlike myself, you’ll remember that for next time, too (me, I’ll be looking for this post again in six months time! 🙂 ).
