改變一個UITableViewCell子視圖的UILabel文本

Question

這是我tableviewcell是如何設置

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]; 
} 

我稍後需要更改程序類別標籤的文本。 我該如何做到這一點？我假設我需要使用標籤來引用UILabel？

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

我想通了......

我把中的UILabel我的頭文件，並改變了代碼，像這樣

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]; 
} 

然後，當我想在以後改變它，我這樣做

categoryLabel.text = @"sample string"; 

最後它發佈了我的dealloc方法。
