Use Lazy Load File for your requirement.

LazyLoad.h
LazyLoad.m

Use them like this

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"cellIdentifier" forIndexPath:indexPath];

    [cell addSubview:[self addViewWithURL:@"http://openwalls.com/image/399/explosion_of_colors_1920x1200.jpg" NFrame:CGRectMake(0, 0, 50, 50)]];

    cell.backgroundColor=[UIColor blueColor];
    return cell;
}

-(UIView*)addViewWithURL:(NSString*)urlStr NFrame:(CGRect)rect
{
    LazyLoad *lazyLoading;

    lazyLoading = [[LazyLoad alloc] init];
    [lazyLoading setBackgroundColor:[UIColor grayColor]];
    [lazyLoading setFrame:rect];

    [lazyLoading loadImageFromURL:[NSURL URLWithString:urlStr]];
    return lazyLoading;
}
