Thanks to an email from Jasper Blues, I can pass along information about an interesting Objective-C dependency injection framework:
Many people have trouble getting the hang of dependency injection, at first. And I think part of the problem is that it is actually so simple that we’re inclined to look for something more complicated. “Surely that there has to be more to it?!”, so to say.
I would agree with the above sentiment. Typhoon is described as follows:
A new dependency injection container for Objective-C. Light-weight, yet full-featured and super-easy to use.
If you are unfamiliar with injection, this is a good place to start.
