iOS 以编程方式更改字体大小不起作用

Question

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        self.backgroundColor = [UIColor clearColor];
        if ([[UIDevice currentDevice].systemVersion floatValue] < 7.0f) {
            self.textLabel.backgroundColor = [UIColor whiteColor];
        }

        _topUserNewName= [[UILabel alloc] init];
        _topUserNewName.textAlignment = NSTextAlignmentLeft;
        _topUserNewName.backgroundColor = [UIColor clearColor];
        _topUserNewName.font = [UIFont fontWithName:@"HelvaticaNeue-Regular" size:5.0];
        _topUserNewName.textColor = [UIColor colorWithRed:(47/255.0) green:(55/255.0) blue:(65/255.0) alpha:1];
        _topUserNewName.frame = CGRectMake(66, 8, 215, 21);


        _topUserName= [[UILabel alloc] init];
        _topUserName.textAlignment = NSTextAlignmentLeft;
        _topUserName.backgroundColor = [UIColor clearColor];
        _topUserName.font = [UIFont fontWithName:@"HelvaticaNeue-Regular" size:10.0];
        _topUserName.textColor = [UIColor colorWithRed:(145/255.0) green:(212/255.0) blue:(210/255.0) alpha:1];
        _topUserName.frame = CGRectMake(66, 37, 210, 21);


        [self.contentView addSubview:_topUserNewName];
        [self.contentView addSubview:_topUserName];


        self.selectionStyle = UITableViewCellSelectionStyleNone;
    }
    return self;
}

此代码在我的表格单元格类中。我想在这里以编程方式更改字体大小，当我更改大小时没有任何变化？ 我在谷歌上研究过这条规则是正确的但没有任何想法？

名称 HelveticaNeue-Regular 实际上并不存在。这应该是 [UIFont fontWithName:@"HelvaticaNeue"size:10.0];。
