Question

I have a tableview which contains some text and I have a label inside tableviewcell as subview, in the label there is also some values. My question is, when I tap the cell I want to get the label value, I know how to get a cell value when tapping the cell but I need to get the label value, my code for getting the tablecell value is

NSString *localStringValue;
localStringValue = [tableView cellForRowAtIndexPath:indexPath].textLabel.text; 

and I display it in a textview textview.text = self.localStringValue;
My label name is chapterandverse, I need to implement this label instead of textlabel.text.
I add localStringValue = [tableView cellForRowAtIndexPath:indexPath].chapterandverse.text;
but I got error for this code. Please help me to do this.
Thanks in advance.

There’s 2 main ways to do this:

1. You can give the chapterandverse label a tag value. In Interface Builder, there is a Tag property on the same page where you set the other properties like Text. If you’re doing it programmatically, chapterandverse.tag = 1;. Then you need to refer to the label by the tag value, like:

   localStringValue = [(UILabel *)[[tableView cellForRowAtIndexPath:indexPath]
                                   viewWithTag:1] text];
   

2. You can do it by having an @property referring to the label in your custom table view cell class. You seem to have already tried to do this, but note that if you call [cell addSubview:chapterandverse] that does not mean you can later say cell.chapterandverse. To make it work properly, you need to make a subclass of UITableViewCell and add the following declaration to it:

   @property (nonatomic, retain) IBOutlet UILabel *chapterandverse;
   

   And then synthesize it in the cell’s .m file:

   @synthesize chapterandverse;
   

   Then you can connect the label you placed in Interface Builder to the chapterandverse outlet on the view and refer to it by cell.chapterandverse like you are doing. If you create it programmatically, though, you will need to initialise the UILabel before using it:

   - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
   {
       self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
       if(self != nil)
       {
           CGRect labelFrame = CGRectMake(x, y, width, height); // set this properly
           self.chapterandverse = [[UILabel alloc] initWithFrame:frame];
           [self.view addSubview:self.chapterandverse];
       }
   
       return self;
   }
