Question

My problem is that I have a UITable, and I cannot get the numberOfRowsInSection to correspond with cellForRowAtIndexPath.

My foodCategoryObj has three arrays, first array has 6 elems, second has 2 and third has 3.

This line
FoodCategory *foodCategoryObj = [appDelegate.foodCategoryArray objectAtIndex:indexPath.row];

..keeps throwing this error.. index 2 beyond bounds [0 .. 1]

Overall I do not know what number to return for numberOfRowsInSection

Also arrayCountInt returns number of objects in the array I have created in viewWillAppear.

- (NSInteger)tableView:(UITableView *)tblView numberOfRowsInSection:(NSInteger)section {

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *arrayCountString = [prefs stringForKey:@"arrayCountString"];
NSInteger *arrayCountInt = [arrayCountString intValue];
//NSLog(@"arrayCountInt.. %i", (arrayCountInt) - 1);


AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSInteger *arrayCount = [appDelegate.foodCategoryArray count];


NSInteger *foodArray = [foodCatArray count];


// testing
NSLog(@"foodCatArray.. %i", foodArray);


return arrayCountInt;
}


- (UITableViewCell *)tableView:(UITableView *)tblView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier];
}

//NSLog(@"indexPath.row.. %i", (indexPath.row)-1);
FoodCategory *foodCategoryObj = [appDelegate.foodCategoryArray objectAtIndex:indexPath.row];

//Set the cell title
cell.text = foodCategoryObj.foodName;


// testing
//NSLog(@"%@", foodCategoryObj.foodName);
//NSLog(@"appDelegate.foodCategoryArray.. %@", appDelegate.foodCategoryArray);

return cell;
}

why don’t you return [appDelegate.foodCategoryArray count] in the numberofrowInSection method. You should return your foodArray and you return the wrong var
