Hi,
I'm in the process of converting an existing iPhone app to use Core
Data for its backend storage. I've got a model that manages an upload

I've subclassed a NSOperation and declared a completion block in the

I'd probably set the managed object as the delegate of your URL connection.
NSURLConnection retains its delegate, and NSURLConnection is itself retained by
the run loop, so you don't have to worry about the managed object disappearing
from underneath you. Then you can simply clean up the conne
By referencing instance variables within the block, you're causing the block to
retain self, and since self retains (copy'd) the block, you've got a retain
cycle.
The easiest way to fix this is to break the retain cycle yourself. Doing
"[self setCompletionBlock:nil];" at the end of the block s
Setting the block to nil within the block itself actually did the trick.
Thank you very much for the quick reply and the correct solution! :)

Have you looked at the sample code for NSUserDefaults ?
I think this IS the place you want to put your info, even though you may not
have realized it yet ;)
You can serialize any data that can take advantage of NSCoding? ie NSData, and
save that as a key value pair.
Also, you should first l

I think you can use NSUserDefaults just fine.
For the exposure example, you might do something like register a

First check for the camera specific key ("QI1438.exposure"), if result

You could wrap that in a single me

Do retained NSManagedObjects never fault, then?

Clustering might be a solution but it's a bit of a heavyweight pattern.

Are you sure in the using of 'library/application support'? There is

Maybe you should save such files in a directory relative to the bundle

[NSBundle mainBundle] will return the path of the application bundle, not

"NSSearchPathForDirectoriesInDomains" with the appropriate masks to search in
