Question

这是我的tableviewcell的设置方式

else if(indexPath.row == 3)
{
    cell.textLabel.text = @"Category";

    UILabel *categoryLabel = [[UILabel alloc] initWithFrame:CGRectMake(150, 2, 145, 34)];
    categoryLabel.adjustsFontSizeToFitWidth = YES;
    categoryLabel.textColor = [UIColor blackColor];
    categoryLabel.font = [UIFont systemFontOfSize:17.0];
    categoryLabel.text = @"select a category";
    categoryLabel.backgroundColor = [UIColor clearColor];
    categoryLabel.textAlignment = UITextAlignmentRight;
    categoryLabel.tag = 3;
    [cell addSubview:categoryLabel];
    [categoryLabel release];
}

我需要稍后在程序中更改类别标签的文本。我该如何做到这一点？我假设我需要使用标签来引用UILabel？

========================

我明白了......

我把UILabel放在我的头文件中并像这样更改了代码

else if(indexPath.row == 3)
{
    cell.textLabel.text = @"Category";

    categoryLabel = [[UILabel alloc] initWithFrame:CGRectMake(150, 2, 145, 34)];
    categoryLabel.adjustsFontSizeToFitWidth = YES;
    categoryLabel.textColor = [UIColor blackColor];
    categoryLabel.font = [UIFont systemFontOfSize:17.0];
    categoryLabel.text = [NSString stringWithFormat:@"%@",categoryFriendlyString];
    categoryLabel.backgroundColor = [UIColor clearColor];
    categoryLabel.textAlignment = UITextAlignmentRight;
    categoryLabel.tag = 3;
    [cell addSubview:categoryLabel];
}

然后当我想改变它时，我做了这个

categoryLabel.text = @"sample string";

最后以我的dealloc方法发布它。
