[amitbattan]

Hi

there is issue in the RTLabel with its frame. its height is not correct. Always shown only one line of text.

Log

updateContentLabel.frame : {{0, 0}, {300, 100}} optimumSize of RTLabel : {296.856, 82}

- (float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return [self rowHeightForRecord:nil];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    float cellWidth = self.tableView.frame.size.width;

// other controls
    RTLabel *updateContentLabel;

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"DataCell"];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"DataCell"] autorelease];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

// other controls

        updateContentLabel = [[RTLabel alloc] init];
        updateContentLabel.tag = 1006;
        updateContentLabel.backgroundColor = [UIColor redColor];
        updateContentLabel.lineBreakMode = RTTextLineBreakModeWordWrapping;
        updateContentLabel.lineSpacing = 20;
        [cell.contentView addSubview:updateContentLabel];

    } else {
// other controls
        updateContentLabel = (RTLabel *)[cell viewWithTag:1006];
    }

    id record = [activityUpdateArray objectAtIndex:indexPath.row];

    triggeredByAvtar.frame = CGRectMake(10, 10, 25, 25);
    triggeredByAvtar.image = [[StarshipImagesServices shared] getImageWithUrl:[record objectForKey:@"TriggeredByProfileImage"]];
    if ( triggeredByAvtar.image == nil ) {
        triggeredByAvtar.image = [UIImage imageNamed:@"img-fetching.png"];
    }

// other controls

    updateContentLabel.frame = CGRectMake(10, 35, cellWidth-20, 300);
    [self setUpdateContent:updateContentLabel forRecord:record];
    CGSize optimumSize = [updateContentLabel optimumSize];
    updateContentLabel.frame = CGRectMake(0, 0, cellWidth-20, 100); // set height 100 for temporary test

// other controls

    return cell;
}

-(void)setUpdateContent:(RTLabel *)contentLabel forRecord:(id)record {

    NSString *string1 = @"this is blue text this is blue text this is blue text this is blue text this is blue text this is blue text this is blue text this is blue text";
    NSString *string2 = @" black black black black black black ";
    NSString *string3 = @"this is blue text this is blue text this is blue text this is blue text this is blue text";

I had the same issue, found solution after initialization of RTlLabel with frame of height 100.

RTLabel *yourLabel = [[RTLabel alloc] initWithFrame:CGRectMake(0,0,100,100)]; then assign text n get optimize height and update frame of yourLabel.
