Hypo Dependency Injection Framework
Wolf Rentzsch (via Edge Cases):
Hypo helps Cocoa coders write loosely-coupled classes. That is, classes that use the services of other classes but try to minimize assumptions.
It’s incredibly lightweight, although I’m not keen on using the _hypo ivar/property name suffix to annotate the required dependencies. With Objection, you would instead add a separate line such as objection_requires(@"engine", @"brakes").
