dynamically increase height of row -iphone - iphone

Question

I am having table view.
I want to dynamically increase the height of the row to some size.
How can I do this.
I know its a silly question.But still can't find the solution.Help me please.
I have used this code.But it is not working :
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UILabel *lblOutTime = [[UILabel alloc]init];
lblOutTime = [[UILabel alloc] initWithFrame:CGRectMake(2, 20, 200, 40)];
lblOutTime.text =#"Outtime : ";
lblOutTime.backgroundColor = [UIColor clearColor];
lblOutTime.font = [UIFont boldSystemFontOfSize:5.0f];
lblOutTime.font = [UIFont fontWithName:#"HelveticaNeue Heavy" size:5.0f];
[cell.contentView insertSubview:lblOutTime atIndex:1];
return cell;
}

Answer 1

-
(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == myIndexPath)
{
return someHeight;
}
return normalHeight;
}
In this case the height is not dynamic. here
is only 2 fixed positions of cell height.
as the if conditions shows.

Answer 2

Here you can change the size of the cell:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
if (indexPath.myRow == myCellIndex)
return NEW_HEIGHT;
else return NORMAL_HEIGHT;
}
And you can reload your table whenever you want with:
[myTable reloadData];

Answer 3

add this tableview delegate method to your class.m file.
Make sure your class conforms to UITtableViewDelegate protocol
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == myIndexPath)
{
return someHeight;
}
return normalHeight;
}

Answer 4

If You Want Increase the height of all row use
[tableView setRowHeight:44];
[tableView reloadData];
if You want increase the height of a particular row use UITableView Delegete heightForRowAtIndexPath:
and use this
[tableView reloadData];

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row <[ListOfCartItems count])
{
CGFloat result = 44.0f;
NSString* text = nil;
CGFloat width =220 ;
clsCart *tempCartPro;
tempCartPro=[ListOfCartItems objectAtIndex:indexPath.row];
text=tempCartPro.clsProductItem.productName;
if (text)
{
CGSize textSize = { width, 20000.0f }; // width and height of text area
CGSize size = [text sizeWithFont:[UIFont boldSystemFontOfSize:15] constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap];
size.height += 90.0f; // top and bottom margin
result = MAX(size.height, result) ; // at least one row
}
return result;
}
else
{
return 230.0;
}
}
