Question

I hava a format problem in cell-subtitle.
I have a string and a number I want to show in subtitle of a cell

String should be left aligned, number right aligned

I tried it in that way:

rangeAutor = [rangeAutor stringByPaddingToLength:40-[rangeAutor length] withString:@" " startingAtIndex:0];

NSString *subTitle = [NSString stringWithFormat:@"by %@ %1.2f km", rangeAutor, rangeDistance];
cell.detailTextLabel.text = subTitle;

result can you see here 🙁 format problem

Do you have an idea for me for a solution?

due to the fact I only have 7 reputation, i cant write in comments my answer 🙁
So i try to do it here:

    static NSString *const kIdentifier = @"SelectRange";
static NSInteger const kDistanceLabelTag = 1;

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kIdentifier];
UILabel *distanceLabel;
if (cell) {
    distanceLabel = (UILabel *)[cell.contentView viewWithTag:kDistanceLabelTag];
} else {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:kIdentifier];
    CGRect cellBounds = cell.bounds;
    static CGFloat const kLabelHeight = 20.0f;
    distanceLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, cellBounds.size.height - kLabelHeight, cellBounds.size.width, kLabelHeight)];
    distanceLabel.tag = kDistanceLabelTag;
    distanceLabel.font = cell.textLabel.font;
    distanceLabel.textColor = cell.textLabel.textColor;
    distanceLabel.textAlignment = UITextAlignmentRight;
    distanceLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;
    [cell.contentView addSubview:distanceLabel];
}

UIImage *icon = [UIImage imageNamed:iconName];;
cell.imageView.image = icon;
cell.textLabel.text = rangeName;
cell.detailTextLabel.text = [@"by " stringByAppendingString:rangeAutor];
distanceLabel.text = [NSString stringWithFormat:@"%1.2f km", rangeDistance];
NSLog(@"RangeDistance: %1.2f", rangeDistance);

return cell;

to rob mayoff

I changed only small things
but now I cant see rangeDistance in the cell 🙁
output of log is ok

The problem is you’re using a variable-width font. Each glyph in the font may have a different width. So you can’t just pad the autor out to 40 characters, because “llll” followed by 36 spaces is a different width (on screen) than “MMMM” followed by 36 spaces.

Just give your cell another label to hold the distance. I assume the code in your post is from your tableView:cellForRowAtIndexPath: method. You’ll need to do something like this:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *const kIdentifier = @"Cell";
    static NSInteger const kDistanceLabelTag = 1;

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kIdentifier];
    UILabel *distanceLabel;
    if (cell) {
        distanceLabel = (UILabel *)[cell.contentView viewWithTag:kDistanceLabelTag];
    } else {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:kIdentifier];
        CGRect cellBounds = cell.bounds;
        static CGFloat const kLabelHeight = 20.0f;
        distanceLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, cellBounds.size.height - kLabelHeight, cellBounds.size.width, kLabelHeight)];
        distanceLabel.tag = kDistanceLabelTag;
        distanceLabel.font = cell.textLabel.font;
        distanceLabel.textColor = cell.textLabel.textColor;
        distanceLabel.textAlignment = UITextAlignmentRight;
        distanceLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;
        [cell.contentView addSubview:distanceLabel];
    }

    cell.imageView.image = rangeImage;
    cell.textLabel.text = rangeName;
    cell.detailTextLabel.text = [@"by " stringByAppendingString:rangeAutor];
    distanceLabel.text = [NSString stringWithFormat:@"%1.2f km", rangeDistance];

    return cell;
}
