iOS objectAtIndex beyond bounds - ios

Question

I have a table that is populated by an array of objects and whenever I call my refresh method that re-populates the array and reloads the table, when I try to read my array in cellForRowAtIndexPath I get a beyond bounds error. I have NSLogged my array to make sure it is populated correctly, and it is. It always is trying to read an index 1 larger than the array is actually. I have no idea why. Any help would be greatly appreciated!
cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"IndexPath = %d", indexPath.row);
// Returns the cell for the given indexPath
static NSString *cellidentifier1 = #"cell1";
static NSString *cellidentifier2 = #"cell2";
self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"dark-background.jpg"]];
self.tableView.separatorColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"dark-background.jpg"]];
// Invisible Cell
if (indexPath.row % 2 == 0) {
UITableViewCell *cell2 = [theTableView dequeueReusableCellWithIdentifier:cellidentifier2];
if (cell2 == nil) {
cell2 = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellidentifier2];
}
[cell2.contentView setAlpha:0];
[cell2 setUserInteractionEnabled:NO];
[cell2 setBackgroundColor:[UIColor clearColor]];
return cell2;
}
// Standard Cell
FCTableViewCell *cell = (FCTableViewCell *)[theTableView dequeueReusableCellWithIdentifier:cellidentifier1];
if (cell == nil) {
cell = [[FCTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellidentifier1];
}
FCCall *currentCall = [[dataController calls] objectAtIndex:((indexPath.row - 1 ) / 2)];
cell.callLabel.text = currentCall.call;
cell.locationLabel.text = currentCall.location;
cell.wcccaNumberLabel.text = currentCall.wcccaNumber;
cell.callNumberLabel.text = currentCall.callnumber;
// Remove leading white space from units string
NSString *units = [currentCall.units stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
cell.unitsLabel.text = units;
cell.stationLabel.text = currentCall.station;
if ([currentCall.county isEqualToString:#"W"]) {
cell.countyImageView.image = [UIImage imageNamed:#"blue.png"];
}
else {
cell.countyImageView.image = [UIImage imageNamed:#"green.png"];
}
if ([currentCall.callType isEqualToString:#"F"]) {
cell.callTypeImageView.image = [UIImage imageNamed:#"red.png"];
}
else {
cell.callTypeImageView.image = [UIImage imageNamed:#"yellow.png"];
}
[cell.unitButton addTarget:self action:#selector(unitButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
cell.unitButton.tag = ((indexPath.section & 0xFFFF) << 16) |
(indexPath.row & 0xFFFF);
[cell.directionsButton addTarget:self action:#selector(directionsButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
cell.directionsButton.tag = ((indexPath.section & 0xFFFF) << 16) |
