Question

I´m using custom cells in a TableView.

The cell height is calculated based on an NSString that is loaded in a UILabel of the cell.
The size is calculated using this function

(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSString *text = [self getTableViewRow:tableView index:indexPath];

CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);

CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

CGFloat height = MAX(size.height, 44.0f);

return height + (CELL_CONTENT_MARGIN * 2) + 60;

}

The size is calculated correctly but when the cell is loaded to the uiTableView, the row has the correct height but the cell does not have.

This is where i create my cell

//Com Custom Cell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"CustomCellIdentifier";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

if (cell == nil) 
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCellApresentacao" owner:self options:nil];

    if ([nib count] > 0 )
        cell = self.tvCell;    
    else
        NSLog(@"Falhou a carregar o xib");
}    

NSInteger row = [indexPath row];

if(self.myTableView1 == tableView)
    labelDescricaoApresentacao.text = [listData1 objectAtIndex:row];
else if (self.myTableView2 == tableView) 
    labelDescricaoApresentacao.text = [listData2 objectAtIndex:row];
else
    labelDescricaoApresentacao.text = [listData3 objectAtIndex:row];  

return cell;
}

i tried to change the cell height in this method using

cell.frame.size.height

but it still didn´t loaded the correct heigth.

Do i have to do anything in the xib of the customCell?
How should i update the cell heigth to the same size has the row?

Answer 1

Where did you set the cell.frame.size.height? I would recommend trying to put it here:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    cell.frame = CGRectMake(0,0,320.0f,30.0f);
}

This method gets called right before the cell is displayed and is a good place to make any visual changes to the cell.
