Great little iBeacon demo app from Nick Toumpelis. This is a simple app but we tested it out here in the office and it worked well. The code is extremely simple and this is a good introduction if you were excited about beacons but hadn't looked at what it takes to broadcast and detect them yet.
Oliver Foggin with a useful replacement for a method with the same name which appeared in the iOS 7 betas but was removed for the final release (I wonder why?). Don't worry too much about the unprefixed category method names in the blog post, the Github repo has prefixed methods so it will be safe if Apple ever add this back to NSCalendar.
Conor Winders with a nice category for reducing the amount of code needed to add motion effects to your UI elements on iOS 7. Strikes me that this could be a good use of outlet collections for the layers of controls to add motion effects to. Hey guys, I finally found a use for outlet collections!
