Wil Shipley continues his Pimp My Code series with an article reviewing what should have been a very simple method to return a path inside the Application Support folder.
Well worth a read, both for the stylistic as well as the comedic commentary.
From my perspective, it is also a useful source of learning about Cocoa from one of the better programmers.
In Python, the final example looks something like:
from Foundation import * def applicationSupportFolder(): return NSSearchPathForDirectoriesInDomains(\ NSApplicationSupportDirectory, NSUserDomainMask, True\ ).stringByAppendingPathComponent_(\ NSProcessInfo.processInfo().processName())
Note: The code has been reformatted to (attempt to) fit your screen.
