Here is the error printed out to the console:

libc++abi.dylib: terminate called throwing an exception
The program breaks exactly at:
NSString *cellValue = [models objectAtIndex:indexPath.row];
from within the cellForRowAtIndexPath: method
Here are all of the tableview methods:
//---set the title for each section---
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
//countyIndex returns the number of counties per state
//in the debugger I checked and the countyIndex is returning the correct number
//of counties!
return [countyIndex objectAtIndex:section];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return [countyIndex count];
}
//---set the number of rows in each section---
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
//---get the county in section---
NSString *county = [countyIndex objectAtIndex:section];
//---get all models from the county---
NSPredicate *predicate =
[NSPredicate predicateWithFormat:@"countyName == %@", county];
NSArray *mods = [modelArray filteredArrayUsingPredicate:predicate];
//---return the number of models from the county---
return [mods count];
}
//models appears to be counted as the number of objects per section
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
// now configure the cell
//---get the county in the current section---
NSString *county = [countyIndex objectAtIndex:[indexPath section]];
//---get all models from the county---
NSPredicate *predicate =
[NSPredicate predicateWithFormat:@"countyName == %@", county];
NSArray *mods = [modelArray filteredArrayUsingPredicate:predicate];
NSMutableArray *newModelArray = [[NSMutableArray alloc] init];
for (NSManagedObject *obj in mods) {
[newModelArray addObject:[NSString stringWithFormat:@"%@",[obj valueForKey: @"model"]]];
}
//get rid of duplicates
NSArray *objectsWithDuplicates = newModelArray;
NSSet *duplicatesRemover = [NSSet setWithArray:objectsWithDuplicates];
models = [duplicatesRemover allObjects];
models = [models sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
UITableViewCell *bgView = [[UITableViewCell alloc] initWithFrame:CGRectZero];
//cell.contentView.backgroundColor = [UIColor whiteColor];
bgView.backgroundColor = [UIColor whiteColor];
cell.backgroundView = bgView;
cell.layer.borderColor = [[UIColor lightGrayColor] CGColor];
cell.layer.borderWidth = .50;
if ([models count]>0) {
//---extract the relevant model from the model object---
NSString *cellValue = [models objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
[cell setAccessibilityTraits:UIAccessibilityTraitButton];
}
return cell;
}
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
//index path to row that's selected
NSIndexPath *myIndexPath = [self.sTable indexPathForSelectedRow];
UITableViewCell *cell = [self.sTable cellForRowAtIndexPath:myIndexPath];
labelText = cell.textLabel.text;
selectedModel = cell.textLabel.text;
}
After doing some commands from console:
po [models count]
po (int)[indexPath row]
I see that it is breaking when the [models count] equals 2 and the [indexPath row] also equals 2, which of course would make it out of range because 2 is actually 3 since the table indexes start at 0.
The question is, why is this occuring? I already reload the tabledata after switching table values, and I went through and counted all the number of rows per section and they appear correct. so why else could this be occuring? the strange thing is this break happens after cellForRowAtIndexPath:(NSIndexPath *)indexPath is re-called as I scroll down in the table.
This happens from within all simulators ios 5.0 - ios 6.1 in Xcode 4.6.1
**EDIT:
I should add that this only happens with the state of California and Wisconsin. I thought this would help narrow it down, but I have checked the databases, and the numbers of counties and models are matching between what is returned in the debugger.
