NSRangeException - Index (2008) beyond bounds (1) - ios

Question

I am trying to get the contents of my UITableViewCell before I delete it from my Core Data model in order to act on its contents. If there is only one item in the Core Data model and I go to delete it from my UITableView, the app will only sometimes throw an error of 2014-01-05 11:10:26.189 Nibbles[43609:70b] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[_PFArray objectAtIndex:]: index (2008) beyond bounds (1)'
My biggest confusion is that this only happens with one item in the UITableView and doesn't happen 100% of the time. If you need to see any other code, please let me know.
Here is the code I am using. The bolded line is the one causing the error since it never makes it past there to NSLog to the console.
// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete) {
NSLog(#"Delete button pressed!");
FoodListCell *cell = (FoodListCell*)[tableView cellForRowAtIndexPath:indexPath];
NSLog(#"DEBUG | Selected Cell: %#", cell);
NSString *foodOrActivity = cell.foodNameLabel.text;
NSString *points = cell.foodPointsLabel.text;
NSManagedObjectContext *localContext = [NSManagedObjectContext MR_contextForCurrentThread];
[[self.fetchedResultsController objectAtIndexPath:indexPath] MR_deleteInContext:localContext];
[localContext MR_saveOnlySelfAndWait];
NSIndexPath *path = [NSIndexPath indexPathForRow:indexPath.row inSection:0];
NSManagedObject *deleteObject = [_fetchedResultsController objectAtIndexPath:path];
[managedObjectContext deleteObject:deleteObject];
}
And here is the full stack trace:

Answer 1

The conventional pattern is to access the model (not through a table cell, but directly from the model). Do whatever you need to do with it, then remove it from your model, then remove it from your table...
The error implies that the localContext being accessed this method is different from (or is in a different state than) the MOC that reports the number of items in the model (used in numberOfRowsInSection:)
Before moving on to recording that deleted object's state, or deleting it. Fix the code that gets that object and just NSLog it. The code that gets that object should exactly match the code that gets it in your cellForRowAtIndexPath:, and the MOC used there should exactly match the numberOfRowsInSection: MOC.

Answer 2

NSIndexPath *path = [NSIndexPath indexPathForRow:indexPath.row inSection:0];
NSManagedObject *deleteObject = [_fetchedResultsController objectAtIndexPath:path];
[managedObjectContext deleteObject:deleteObject];
Here you are getting the index path for the row in section 0 and deleting it.
You already have the index path for the row/cell/section that you want to delete, so why are you trying to delete that row only in section 0?
Try a breakpoint at this line and add some logging to show what row in section 0 is trying to be deleted.
