Interestingly, I just learned that most people's unit-tests are not actually testing all paths. When people follow jamisbuck's suggestion, they end up with two ways to get at nested resources. Their unit-tests will generally get/post to the simplest:

UIButton: Making the hit area larger than the default hit area

First, add a category to UIButton that overrides the hit test and also adds a property for expanding the hit test frame.

Dealing with commas in a CSV file
... including embedded quotes and carriage returns.
By the way, this is unit-tested code. I’m posting it now because this question seems to come up a lot and others may not want an entire library when simple CSV support will do.
You can use it as follows:
