Thanks everyone again!
I have found nice working example here

I need to implement Grid view for iOS 7 and newer.
The users should have ability to scroll its contents both horizontally and
vertically.
They also should have ability to mark the very first row and column as fixed
i.e. non-scrollable.
A UITableViewController will take care of the vertical scrolling for you. You
just need to add horizontal scrolling views to each cell and to the section
header.
Here's a fairly easy way that works very well:
1. Create a UITableViewController (your own subclass of it), as normal
2. In tableView:cellForRowAtIndexPath: call createColumnsInView:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
BOOL doCreateColumns = [cell.contentView viewWithTag:scrollViewTag] ==
nil;
if (doCreateColumns)
{
[self createColumnsInView:cell.contentView];
}
// Configure cell here
return cell;
}
3. Implement createColumnsInView: to add a UIScrollView which contains the
columns you want (eg multiple UILabels). Set the UIScrollView's
contentSize.width to the required width to encompass all of the columns and set
the delegate to self (ie the UITableViewController subclass). Set the other
properties as shown:
- (void)createColumnsInView:(UIView*)containerView
{
UIScrollView* scrollView = [[UIScrollView alloc]
initWithFrame:containerView.bounds];
scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight |
UIViewAutoresizingFlexibleWidth;
scrollView.scrollsToTop = NO;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.showsHorizontalScrollIndicator = NO;
scrollView.alwaysBounceVertical = NO;
scrollView.alwaysBounceHorizontal = NO;
scrollView.directionalLockEnabled = YES; // otherwise user can start
scrolling horizontal then vertical
scrollView.tag = scrollViewTag;
scrollView.delegate = self;
[containerView addSubview:scrollView];
// Probably add your columns (eg series of UILabels) here.
scrollView.contentSize = CGSizeMake(totalWidthRequiredForColumns,
scrollView.frame.size.height - 1); // -1 so doesn't scroll vertically
}
4. Implement tableView:viewForHeaderInSection:section, returning a view
containing the same sized scrollview that you return in cells. This will be
your fixed non vertically scrolling header.
- (CGFloat)tableView:(UITableView *)tableView
heightForHeaderInSection:(NSInteger)section
{
return sectionHeight;
}
- (UIView*)tableView:(UITableView *)tableView
viewForHeaderInSection:(NSInteger)section
{
return self.sectionHeader;
}
- (UIView*)sectionHeader
{
if (_sectionHeader == nil)
{
_sectionHeader = [[UIView alloc] initWithFrame:CGRectMake(0, 0,
320, sectionHeight)];
_sectionHeader.backgroundColor = [UIColor colorWithRed:1.0
green:1.0 blue:0.8 alpha:0.8];
[self createColumnsInView:_sectionHeader];
}
return _sectionHeader;
}
5. Implement scrollViewDidScroll: to synchronize horizontal scrolling of all
the UIScrollViews:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
if (scrollView != self.tableView)
{
NSMutableArray* containers = [NSMutableArray
arrayWithObject:self.sectionHeader];
[containers addObjectsFromArray:self.tableView.visibleCells];
for (UIView* container in containers)
{
UIScrollView* containerScrollView =
(UIScrollView*)[container viewWithTag:scrollViewTag];
containerScrollView.contentOffset =
scrollView.contentOffset;
}
}
}
Hope this helps,
