Update UITableView Cell imageView by Tag - ios

Question

Is it possible to update the cell imageView in an iOS UITableView by tag? I appreciate other methods are available but I would like to use tags if possible.
I set the image by:
cell.imageView.image = [UIImage imageNamed:#"dinner.png"];
And in another method I can get the cell by (Tags are always unique):
NSInteger the_tag = ((UIView*)sender).tag;
UITableViewCell *updateCell = (UITableViewCell*)[tableView viewWithTag:the_tag];
Is it possible to update the cell with this method? This does not work:
updateCell.imageView.image = [UIImage imageNamed:#"lunch.png"];
EDIT:
On reflection, the tags are bad method to use. You can use (Which will give you the row and the section if you have a sectioned table):
- (void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {
NSLog(#"Tapped Row %#", indexPath);
UITableViewCell *cell = [self->tableView cellForRowAtIndexPath:indexPath];
cell.imageView.image = [UIImage imageNamed:#"lunch.png"];
}

Answer 1

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
CustomCell *cell = (CustomCell*)[tblView1 cellForRowAtIndexPath:indexPath.row];
UIImageView *imageView = cell.imageView;//CustomCell you have imageView as #propertyVariable..
imageView.image = [UIImage imageNamed:#"image.png"];
}
I hope it will be helpful for you...

Answer 2

try calling [updateCell setNeedsLayout] or [updateCell.imageView setNeedsLayout]

Answer 3

Thank you for all the answers. On reflection, I feel tags are a bad method to use. I have updated my original post with what I feel is a better solution.

Answer 4

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.tag = indexPath.row;
cell.imageView.image = [UIImage imageNamed:#"icon.png"];
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
int tag = 2;//this is same at table cell row number.
UITableViewCell *cell = (UITableViewCell*)[tableView viewWithTag:tag];
cell.imageView.image = [UIImage imageNamed:#"image.png"];
}
