• This code has been known to work on iOS 5.x+.
• This code uses Automatic Reference Counting, if your project does not use ARC, you must add the -fobjc-arc compiler flag to each implementation files in Target Settings > Build Phases > Compile Source.
• This code also uses the literals syntax, so at least Xcode 4.5 is required.

If you're using CocoaPods, there's nothing simpler. Add the following to your Podfile and run pod install
