Auto calculate height for rows and sub-rows

[brbgyn]

Hi, i implemented the auto-heigh for rows and sub-rows.

Hope to see it on project and help other developers.

Code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
...
    cell.textLabel.numberOfLines = 0;
...
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForSubRowAtIndexPath:(NSIndexPath *)indexPath
{
...
    cell.textLabel.numberOfLines = 0;
...
}

- (CGFloat)tableView:(SKSTableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *item = self.contents[indexPath.section][indexPath.row][0];

    CGFloat textHeight = [self getLabelHeightForText:item andWidth:tableView.bounds.size.width];
    return textHeight + 20;
}

-(CGFloat)tableView:(SKSTableView *)tableView heightForSubRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *item = self.contents[indexPath.section][indexPath.row][indexPath.subRow];

    CGFloat textHeight = [self getLabelHeightForText:item andWidth:tableView.bounds.size.width - 20];
    return textHeight + 20;
}

-(CGFloat)getLabelHeightForText:(NSString *)text andWidth:(CGFloat)labelWidth
{
    CGSize maximumSize = CGSizeMake(labelWidth, 10000);
    CGSize labelHeighSize = [text sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:maximumSize lineBreakMode:UILineBreakModeTailTruncation];
    return labelHeighSize.height;
}

sorry; but i faced new problem; when i select first time auto calculation for height for sub row not working; but with second selection or when close the row and open again its working perfect; can you help

I don't have the code here with me, but maybe if you try to force recalculation on view did appear, or to programmatically touch on the first row to force the row height recalculation, i don't know.. Maybe one of this could work
