ios - 新手需要帮助 : Bold Font & Text Colour Based on Value

Question

我想在下方将 sl.asl 设为粗体，并根据下方的数值为其着色。有什么想法吗？

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateStyle:NSDateFormatterShortStyle];

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}


// Configure the cell...
ServiceLevel *sl = (ServiceLevel *)[self.importedRows objectAtIndex:indexPath.row];
cell.textLabel.text = [NSString stringWithFormat:@"%@ - %@", sl.name , sl.asl];

return cell;
}

NSAttributedString 应该可以解决这个问题。

喜欢:

    NSString *name = @"SampleName";
    NSUInteger asl = 2;
    NSString *t_string = [NSString stringWithFormat:@"%@ - %d", name , asl];

    NSUInteger t_nameLength = name.length;
    NSUInteger t_aslLength = 1;

    UIColor *t_color = nil;
    switch (asl) {
        case 1:
            t_color = [UIColor redColor];
            break;
        case 2:
            t_color = [UIColor greenColor];
            break;
        default:
            t_color = [UIColor blackColor];
            break;
    }

    NSMutableAttributedString *t_attributedString = [[NSMutableAttributedString alloc] initWithString:t_string];
    [t_attributedString addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial" size:14.0] range:NSMakeRange(0, t_nameLength)];
    [t_attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, t_nameLength)];
    [t_attributedString addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Arial-BoldMT" size:14.0] range:NSMakeRange(t_nameLength + 3, t_aslLength)];
    [t_attributedString addAttribute:NSForegroundColorAttributeName value:t_color range:NSMakeRange(t_nameLength + 3, t_aslLength)];

    cell.textLabel.attributedText = t_attributedString;
