The problem was that I access a file (without proper error-
handling; I will add that now :-)). The default working directory
is the main-bundle path when run from within XCode and it is "/"
when run from Finder.
I repaired this by adding
[[NSFileManager defaultManager] changeCurrentDirectoryPath:
[[[NSBundle mainBundle] bundlePath]
stringByDeletingLastPathComponent]];
to my awakeFromNib. I hope this works as I intend.
That will work, although if any other -awakeFromNib method (of an
object in that nib) wants to use a relative path, you have a race
condition, because the order in which -awakeFromNib methods are
called is, basically, random.
But it's better to just avoid using relative paths, if possible. If
you're accessing a file inside your bundle, you should use the
NSBundle resource APIs to get its location.
Let me echo what Jens said. The cwd is for command-line tools; don't
use it, or anything that relies on it, in an application context, if
you can do anything to avoid it.
