如何在UITableViewCellStyleSubtitle中显示多行

Question

So I have a download manager in my app. I have taken it upon myself to liven it up today.

I have implemented UITableViewCellStyleSubtitle, and is displaying properly.

I want to add more than 1 line to it. Right now I'm stuck in choosing either the file size or the formatted date.

How would I do both? ie

Cell Title
Date: (followed by file size) or
File Size:

Below is the relevant code I'm working with.

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        static NSString *CellIdentifier = @"Cell";
        UITableViewCell *cell = [(UITableViewCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier] autorelease];
        if (cell == nil) {
            cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
            [cell setSelectionStyle:UITableViewCellSelectionStyleBlue];
        }

    // Configure the cell.
        cell.textLabel.text = [directoryContents objectAtIndex:indexPath.row];
        cell.accessoryType = UITableViewCellAccessoryNone;
        [cell.layer setBorderColor:[UIColor colorWithRed:30/255.0 green:30/255.0 blue:30/255.0 alpha:1.0].CGColor];
        [cell.layer setBorderWidth:1.5f];
        cell.textLabel.numberOfLines = 0;


    //Get file size
        NSError *error;
        NSString *fileName = [directoryContents objectAtIndex:indexPath.row];
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"my folder"];
        path = [path stringByAppendingPathComponent:fileName];

        NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:path error:&error];
        NSInteger fileSize = [[fileAttributes objectForKey:NSFileSize] intValue];

    //Setting the date
        NSFileManager *fileManager = [NSFileManager defaultManager];
        NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
        NSString *filePath = [documentsPath stringByAppendingPathComponent:@"my folder"];
        filePath = [filePath stringByAppendingPathComponent:fileName];

        NSDate *creationDate = nil;
        NSDictionary *attributes = [fileManager attributesOfItemAtPath:filePath error:nil];
        creationDate = attributes[NSFileCreationDate];

        NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"MM-dd-yyyy"];
        NSString *dateString = [dateFormatter stringFromDate:creationDate];


/////This is where I need to blend the dateString with the file size//////
        cell.detailTextLabel.text = [NSString stringWithFormat:dateString, @"%@", [self formattedFileSize:fileSize]];
        cell.detailTextLabel.numberOfLines = 2;

        return cell;
    }

Thank you in advanced.

Answer 1

I tried this out, and for some reason, setting numberOfLines to 2 didn't work for me either, but setting it to anything greater then 2, or setting it to 0 worked.

You need to format your two strings properly. This is not correct syntax,

[NSString stringWithFormat:dateString, @"%@", [self formattedFileSize:fileSize]]

It should be like this,

[NSString stringWithFormat:@"%@\n%@",  dateString, [self formattedFileSize:fileSize]];

Answer 2

Figured this out. Just had to tweak around with the format of the string.

cell.detailTextLabel.text = [NSString stringWithFormat:@"%@\n%@", dateString, [self formattedFileSize:fileSize]];

As posting this answer the page refreshed and seen that rdelmar is also correct in his updated post showing the proper syntax.

Credit and thanks to him for the help in helping me think this out.
