Question

I am trying to get the UITableView cells to fit the text. So far I have something like this:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UILabel *label = nil;

    UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:(UITableViewCellStyleDefault)
            reuseIdentifier:@"business"];

    NSString *comment = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"comment")];

cell.textLabel.numberOfLines = 0;
        cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;

        CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f);

        CGSize size = [comment sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];


        label = [[UILabel alloc] initWithFrame:CGRectZero];

        [label setText:comment];
        [label setFrame:CGRectMake(10, 10, 320 - (10 * 2), MAX(size.height, 44.0f))];

        cell.textLabel.text = comment;  
    }

I also have this function

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{    
    NSString *comment = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"comment")];

    CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f);

    CGSize size = [comment sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

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

    return height + (10 * 2);
}

But it isn’t allocating the right amount of height to the cells of the UITableViews. I think I am making some mistakes with how/where I assign the label and the text of the cells.

Please help me understand how it should be.

Thanks!

Answer 1

does this get you closer?

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"business"]; 

 if (cell == nil)
 {  
  cell = [[UITableViewCell alloc] initWithStyle:(UITableViewCellStyleDefault)reuseIdentifier:@"business"]; 
 }

 NSString *comment = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"comment")]; 

 CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f); 

 CGSize size = [comment sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap]; 

 UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 300, MAX(size.height, 44.0f) + 20.0f)]; 
 label.numberOfLines = 0; 
 label.lineBreakMode = UILineBreakModeWordWrap; 
 label.text = comment;  

 [cell.contentView addSubview:label]; 

}
