Always use the async API.
For networking, there are *tons* of reasons to avoid your own threading (ie,
CPU -> battery consumption) when Apple does all that for your using their Async
API (and only one global thread to manage the network)

Hi,
Whats the best way to pass a NSManagedObjectContext object from an app delegate
to other view controllers?
Currently, my NSManagedObjectContext is retained like this in my app delegate:
@property (nonatomic, retain, readonly) NSManagedObjectContext
*managedObjectContext;

Hello Gustavo.
This sounds like a perfect job for Core Animation.
With Core Animation, you can apply the animation to the UIImageView's layer.
Core Animation allows for animations to run once and stop automatically, repeat
a specific number of times, or repeat indefinitely until you tell it to st

Hi Quincey
Thanks for the speedy reply. I'll look into having the root entity either parse
from a plist or something similar.
Hmm, it just occured to me that I can put json strings in the user info, and
parse them back into the user info. That would enable me to put complex nested
dictionaries

Hi all,
I have a Core Data model and I'd like to add some metadata about the
entities/attributes/relationships. In most cases, strings are fine, but I'd
also like to record arrays or even sub-dictionaries. This will reduce the
amount of code in my app by a fair deal.

Hi folks,
I'm trying to figure out a clear guideline on how to handle weak references.

1- Say I have a button, and set its action/target (via a nib file) to call
method on the controller. In the controller dealloc method, should the
controller set the actio
I've got the following code that is almost identical to code I've got

difference between the two is the variable names;

No. It is the responsibility of the delegate to set the table view's
backpointer to nil. The delegate usu
