How can I do variable height table cells on the iPhone properly?

Question

My app needs to have variable height table cells (as in each table cell differs in height, not that each cell needs to be able to resize itself).

I have a solution t

Here's what I use. NSString has a method that will tell you the dimensions of a textbox based on the font information and the height/width constraints you give it.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *text = [self getTextForIndexPath:indexPath];
    UIFont *font = [UIFont systemFontOfSize:14];
    CGSize size = [self getSizeOfText:text withFont:font];

    return (size.height + 11); // I put some padding on it.
}

Then you write a method pull the text for this cell...

- (NSString *)getTextForIndexPath:(NSIndexPath *)indexPath
{
    NSString *sectionHeader = [self.tableSections objectAtIndex:[indexPath section]];
    NSString *sectionContent = [self.tableData objectForKey:sectionHeader];

    return sectionContent;
}

And this is to get the size of the text.

- (CGSize)getSizeOfText:(NSString *)text withFont:(UIFont *)font
{
    return [text sizeWithFont:font constrainedToSize:CGSizeMake(280, 500)];
}
