NSDictionary selected on Actionsheet, from a UITableView with Custom Cells - json

Question

I am working on a big learning experience, adding a NSDictionary that uses a JSON(deserializer) to grab content from my MAMP(myphp admin) server (localhost), and put all's this information nicely in a TablewView, which has custom UITableViewCell's,
my problem is, the Table View loads the information from my server just fine, however, when I use the didSelectRowatIndexPath, with an actionsheet, I can get the actionsheet to come up, however I cannot get it to pull the information from my NSDictionary that was previously used in the UITableView.... (basically in the end, the action sheet will have a few buttons, for example loading a URL from a shared application, and all this information will be grabbed from my server using the same NSDictionary in the UITable View.
any help would greatly be appreciated...... thank you so much this community rocks!!!

It's the rows, they are being autoreleased. Here's the important lines.
The first line in the viewDidLoad retains the rows correctly
rows = [[dict objectForKey:#"users"] retain];
But you sort these rows in the cellForRowAtIndexPath and did not retain it.
rows = [rows sortedArrayUsingDescriptors:[NSArray arrayWithObject:ratingsSortDescriptor]];
This should be something like:
NSArray *sortedRows = [rows sortedArrayUsingDescriptors:[NSArray arrayWithObject:ratingsSortDescriptor]];
[rows release];
rows = [sortedRows retain];
Hope this helps.
