Applying a UIImageView to only a specific section in a UITableView - ios

Question

I have a simple application which is made up of a UITabBar where each Tab is a UITableViewController. For the purpose of this question, I will only focus on the UITableViewController called Videos (1st Tab) and another UITableViewController called Languages (2nd Tab).
The Videos Tab is made up of one section of a list of Videos. The Languages tab contains two sections, where section 0 is Leaflets and section 1 = the same corresponding Videos as the Videos tab.
So for example, if the Videos tab has:
Video 10010
Video 20010
Video 30010
Video 40010
Video 50010
Then the Languages tab section 1 will also have:
Video 10010
Video 20010
Video 30010
Video 40010
Video 50010
I have some code which puts a star on any cell that has been selected and the title of this cell is getting added to Core Data (to be displayed in the 3rd tab called Favourites - but this isn't important for this question).
I want to ensure consistency within the app, so if I place a star in Video 20010 in the Videos tab, I want to make sure that the Video 20010 in the Languages also has a star.
That part works. However, the issue is that the star gets placed in the Leaflets section (section 0) as well as the Videos section (section 1) of the Languages tab.
Here is part of the code of the cellForRow in the Languages tab.
// This code is important because I might set the Leaflets section to be a favourite from within the Languages tab (not related to the Videos tab, etc).
if(indexPath.section==0)
{
customCell.customCellLabel.text = [NSString stringWithFormat:#"%#",[self.availableLeaflets objectAtIndex:indexPath.row]];
NSString *key = [NSString stringWithFormat:#"%#_%ld_%ld", self.selectedLanguage, (long)indexPath.section, (long)indexPath.row];
if (self.favoritesDict[key]) {
// show the favorite image
customCell.customCellImage.hidden = NO;
} else {
// hide the favorite image
customCell.customCellImage.hidden = YES;
}
}
else
{
customCell.customCellLabel.frame = CGRectMake(8, 20, 100, 40);
customCell.customCellLabel.text = [NSString stringWithFormat:#"%#",[self.availableVideos objectAtIndex:indexPath.row]];
NSString *key = [NSString stringWithFormat:#"%#_%ld_%ld", self.selectedLanguage, (long)indexPath.section, (long)indexPath.row];
if (self.favoritesDict[key]) {
// show the favorite image
customCell.customCellImage.hidden = NO;
} else {
// hide the favorite image
customCell.customCellImage.hidden = YES;
}
}
NSManagedObjectContext *context = [self managedObjectContext];
NSFetchRequest *request = [NSFetchRequest fetchRequestWithEntityName:#"Favourites"];
request.predicate = [NSPredicate predicateWithFormat:#"title != nil"];
NSSortDescriptor *sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:#"title" ascending:YES];
request.sortDescriptors = [NSArray arrayWithObject:sortDescriptor];
NSError *error = nil;
NSArray *favs = [context executeFetchRequest:request error:&error];
if (!favs)
{
NSLog(#"Nothing to see here");
}
else
{
NSLog(#"Number of objects %lu", [favs count]);
for (Favourites *favourite in favs)
{
NSString *string = [NSString stringWithFormat:#"%#", favourite.title];
favourite.title = string;
NSLog(#"The favourite titles are %#", favourite.title);
if ([customCell.customCellLabel.text isEqualToString:favourite.title])
{
customCell.customCellImage.hidden = NO;
}
}
}
Update
When a cell is favourited, this is what's happening:
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
CustomLeafletVideoTableViewCell *selectedCell = (CustomLeafletVideoTableViewCell*)[self.tableView cellForRowAtIndexPath:indexPath];
NSString *cellTitle = selectedCell.customCellLabel.text;
NSLog(#"The text is %#", cellTitle);
NSManagedObjectContext *context = [self managedObjectContext];
NSString *key = [NSString stringWithFormat:#"%#_%ld_%ld", self.selectedLanguage, (long)indexPath.section, (long)indexPath.row];
if (self.favoritesDict[key] == nil)
{
self.favoritesDict[key] = #(1);
Favourites *favourites = [NSEntityDescription insertNewObjectForEntityForName:#"Favourites" inManagedObjectContext:context];
favourites.title = cellTitle;
}
else
{
[self.favoritesDict removeObjectForKey:key];
NSError *error;
NSFetchRequest *request = [[NSFetchRequest alloc] init];
request.entity = [NSEntityDescription entityForName:#"Favourites" inManagedObjectContext: context];
request.predicate = [NSPredicate predicateWithFormat:#"title == %#", cellTitle];
NSArray *items = [context executeFetchRequest:request error:&error];
if (error == nil && items.count)
{
NSManagedObject *managedObject = items[0];
[context deleteObject:managedObject];
}
}
[[NSUserDefaults standardUserDefaults] setObject:self.favoritesDict forKey:#"favoritesDict"];
NSError *error = nil;
if (![context save:&error])
{
// Error
}
[cell hideUtilityButtonsAnimated:YES];
[self.tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
I am not interested in putting the image in the Leaflets section of the Languages tab (section 0); I just want to target the Videos section (section 1). With this code above, the correct cell in section 1 is getting the UIImageView being applied, but I want to make sure the first section (Leaflets) is NOT getting the star as well.
Any guidance on this would be really appreciated.

Answer 1

Right after you dequeue the cell say customCell.customCellImage.hidden = YES; Then change:
if ([customCell.customCellLabel.text isEqualToString:favourite.title])
{
customCell.customCellImage.hidden = NO;
}
To:
if ([customCell.customCellLabel.text isEqualToString:favourite.title] && indexPath.section == 1)
{
customCell.customCellImage.hidden = NO;
}

Answer 2

In tableView:cellForRowAtIndexPath:, you have the key part, which is the indexPath. Add the following condition to your if statement.
indexPath.section == 1
