how to add UITableviewcell subview as uiscrollview - ios

Question

I have UITableViewCell subview as UIScrollview and UIscrollview as dynamic uilabels and i need to scroll horizontally with pagination. but i need to scroll synchronously all the table view cell. problem is not able to scroll all the cell togeather.
here is my source code.
Customcell source:
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
//ScrollView
self.kpiScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 300, 70)];
[self.kpiScrollView setPagingEnabled:YES];
[self.contentView addSubview:self.kpiScrollView];
[self.kpiScrollView release];
NSArray *colors = [NSArray arrayWithObjects:[UIColor grayColor], [UIColor greenColor], [UIColor blueColor], nil];
for (int i =0; i<colors.count; i++) {
CGRect frame;
frame.origin.x = self.kpiScrollView.frame.size.width *i;
frame.origin.y = 0;
frame.size = self.kpiScrollView.frame.size;
subView = [[UIView alloc] initWithFrame:frame];
subView.backgroundColor = [colors objectAtIndex:i];
[self.kpiScrollView addSubview:subView];
[subView release];
}
self.kpiScrollView.contentSize =
CGSizeMake(self.kpiScrollView.frame.size.width*colors.count,
self.kpiScrollView.frame.size.height);
}
}
and TableView source:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"CellIdentifier";
PageCell *cell = (PageCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[[PageCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]autorelease];
}
// cell.pageDelegate = self;
cell.self.kpiScrollView.delegate= self;
cell.tag = indexPath.row+1;
NSLog(#"cell tag:%d", cell.tag);
return cell;
}
UIScrollView delegate methods:
- (void)scrollViewDidScroll:(UIScrollView *)sender {
if (kpiScrollView == self.kpiTableView) {
return;
}
CGPoint contentOffset = kpiScrollView.contentOffset;
for (PageCell *cell in [self.kpiTableView visibleCells]) {
cell.kpiScrollView.contentOffset = contentOffset;
}
}

Skimming the code, not sure if there are other problems, but the first thing to fix is where you get the content offset....
- (void)scrollViewDidScroll:(UIScrollView *)sender {
// note the change here...
if (sender == self.kpiTableView) return;
// get the content offset from the cell's scrollview that posted this delegate message
CGPoint contentOffset = sender.contentOffset;
for (PageCell *cell in [self.kpiTableView visibleCells]) {
cell.kpiScrollView.contentOffset = contentOffset;
}
}
