Delete / move UITableView string attached to web service

Question

Removing or moving rows for a UITableView supported by local data (e.g. NSArray) is easy and instant:

• Remove value from array.
• Challenge deleteRowsAtIndexPaths:withRowAnimation:.
• Profit!

But my view of the table interacts with the web service, which means that after clicking the "Delete" button on this line I need to send a request to the server (via ASIHTTPRequest , of course), get a response, and then tell the table view to start a little animation with deletion , all with a gap of a few seconds between them.

From a high level, what is the best way to do this? Throw multiple callback selectors in the ASIHTTPRequest userInfo dictionary? KVO ?

Bonus points for a nice interface, for example, some kind of counter in a cell that will be deleted soon.

Answer 1

The most elegant way I know is to use Core Data for local data and listen to the UITableView for change notifications from the Core Data repository. This supports model / view separation, and yet you can still get a glamorous animation of the string animation. This happens as follows:

• The user says to delete the line.
• ASIHTTPRequest , , .
• , , .
• UITableView , , .

, , . , , , , - , , - , , ASIHTTPRequest /; , , . , , , - . Core Data "" , , , .

Core Data, KVO - .

: , , , Core Data , "ForDeletion" -; ASIHTTPRequest, , markForDeletion true. UITableView ( ); , , . - , , . , ASIHTTPRequest , ; , " " false, UITableView .
