NSNull+TypeAdditions is a category on NSNull that automatically sanitizes null inputs by providing implementations of common primitive type accessors. They return initialized blank values instead of crashing. This is super useful for web APIs that think that returning "null" won't crash NSJSONSerializer.
NSNull+TypeAdditions is on CocoaPods, so you can install it with this line at the end of your Podfile
pod 'NSNull+TypeAdditions'
