Consider the multi-threaded case where you want property access to be atomic
(and remember, properties might not always be object
round in InGameViewController's implementation of -viewDidUnload and see
if you're doing anything that involves '[self view]' (or 'self.view' for you
dot-syntax people :) ).

What are you really trying to do?
In general, resource forks on Mac OS X aren't used anymore. NSFileManager
preserves them on file moves and copies for legac. And while the "..namedfork"
bits work now, they're unlikely to continue working in the future.

4u; NSDictionaryController is tagged as being
available in 10.5 (Leopard) and later.
So Tiger's unarchiver doesn't know what to do with an archived
NSDictionaryController. There's a setting in Interface Builder which should
warn you about this kind of thing - if you're set
tion because it's basically using what's
available in the stat() block and nothing else.
You should be fine in just using NSFileManager and asking for fileAttributes
using an NSDirectoryEnumerator. And as that gets faster, you'll get faster. If
you're that worried about it,
is also a good resource.
You can also write your own dtrace scripts to track messages to
retain/release/autorelease to your own objects and that can help filter down
the noise to only those objects of the class which are causing you problems.

As Clark noted elsewhere, you're using a string key properly with
NSUserDefaults itself and NSUserDefaults and CFPreferences both require that
the entire subtree of the value be a properly formed property list object.
For NSDictionaries that means all keys must be strings for the entire tree. Th
Please remember that gethostuuid() has all the same caveats mentioned

t's probably complaining about the
MDItemCopyAttributeNames() call, which (because it has "Copy" in the

It's just not safe, unless you can guarantee that you own the entire

that's not necessary either).
When the user runs the application again, retrieve the dictionary and
use those values to call -[NSNetService initWithDomain:type:name:].
That call returns an NSNetService suitable for res

You should just use NSTemporaryDirectory().

Another is to use the "persistent domain" capabilities of
NSUserDefaults. Pull in the dictionary for the domain, make a
mutable copy, modify it, and then write the whole domain back out.
This is overkill; use the CFPreferences API instead.

As far as parsing arguments go, you may wish to look at using
[[NSProcessInfo processInfo] arguments], which gives you an NSArray of
