I hadn't come across uncrustify before but it looks like a good tool for keeping code formatting preferences in check across a team. Tony Arnold gives Xcode 4 some uncrustify integration with these automator workflows.
This is quite old code but I came across a link to it this week. Leah Culver's gives us her take on a pull to refresh table view controller. Yes there is lots of pull to refresh code out there but we can always use more right?
