Artifact 1a4f4e7d5d61f4da39ce45031b235a6f11cb451caec4752ebda21eaa72aa18cf:

• File src/OFINICategory.h — part of check-in [0a73af49f0] at 2017-04-30 13:35:16 on branch trunk — Use nonatomic for properties and clean up

  This changes retaining behavior, meaning properties are not returned
  retained and autoreleased anymore, so a property returned from a getter
  now needs to be manually retained and autoreleased before calling the
  setter. However, this is rarely the case and not using atomic improves
  performance. (user: js, size: 7808) [annotate] [blame] [check-ins using]
