How can I display UILabel "No result found" in cell if no collectionview item?

Question

I would like to display UILabel "No result found" in cell ("HomeProductCell" as below") if no data in collectionview. How can I set for this label in cell? Please help.

Here is my code:-

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {

    if (section == 3) { //Product

        if(_youLikeItem.count >0)
        {
           return _youLikeItem.count;  
        }

    }
    return 0;
} 


- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    UICollectionViewCell *gridcell = nil;

    if (indexPath.section == 3) {
        HomeProductCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:HomeProductCellID forIndexPath:indexPath];

        if(_youLikeItem.count > 0){

            cell.productImage = [_youLikeItem[indexPath.row]valueForKey:@"image"];
            cell.productName = [_youLikeItem[indexPath.row]valueForKey:@"name"];
            cell.productPrice = [_youLikeItem[indexPath.row]valueForKey:@"price"];

            gridcell = cell;
        }
        else
        {
            UILabel *noDataLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, collectionView.bounds.size.width, collectionView.bounds.size.height)];
            noDataLabel.text = @"No product(s) available";
            noDataLabel.textColor = [UIColor grayColor];
            noDataLabel.font = PFR18Font;
            noDataLabel.textAlignment = NSTextAlignmentCenter;
            [cell addSubview:noDataLabel];

        }
    }

Answer 1

Make sure that you indicate that there's at least 1 item in section 3:

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    if (section == 3) { //Product
        if (_youLikeItem.count > 0) {
           return _youLikeItem.count;  
        } else {
           return 1;
        }
    }
    return 0;
}

That will do the trick. If you want to be extra careful then in collectionView:cellForItemAtIndexPath: you can change

if(_youLikeItem.count > 0){

to

if (indexPath.item < _youLikeItem.count) {

(N.B. For collection views you should use indexPath.item, not indexPath.row.)
