need help with heightForRowAtIndexPath please

[Leon112]

hello, ive been struggling to assign dynamic height for my cell in the table, ive tried many thing but none of them worked... from reading i gather that my best way or rather only way to do this is by using heightForRowAtIndexPath.. can some one assist me please on where and how i should be using this? below is my code.

// Customize the appearance of table view cells.
- (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] autorelease];
    }

	

    // Configure the cell.
    [self configureCell:cell atIndexPath:indexPath];
    
    return cell;
}

- (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath {
    
    NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:indexPath];
	cell.textLabel.text = [[managedObject valueForKey:@"text"] description];
	

	cell.textLabel.numberOfLines = 0;

	cell.textLabel.font = [UIFont systemFontOfSize:16];

    
}

hello , sorry for my quick reply but it always happens right after i post something here... i think i just figured it out using the below code but not sure if i am doing it right....

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
	NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:indexPath];
	NSString *temp = [[managedObject valueForKey:@"text"] description];
	
	struct CGSize size;
	size = [temp sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:CGSizeMake(300.0, 4000) lineBreakMode:UILineBreakModeCharacterWrap];
	return size.height * 1.5;	
}

any ideas? help?

Couple of things to correct...
1. Specify the same line break mode while creating the cell...
2. Don't give font size different while creating cell and calculating height of cell.

Also, in height function, return size.height (not size.height * 1.5) unless you are sure of what you are doing here. Add some delta (20 something) to it, don't scale it.

I hope it helps.
