Question

I have a table view. I originally used the cell’s textLabel to handle this, but that didnt work, so i added a UILabel to each cell programatically and i have two buttons a add button and a subtract button which basically counts up or down when pressed. (goes up or down by 1) The methods for the two buttons are:

 - (IBAction)addLabelText:(id)sender{    
   cellLabel.text = [NSString stringWithFormat:@"%d",[cellLabel.text intValue] +1];

}  

- (IBAction)subtractLabelText:(id)sender
{
    if ( [[cellLabel text] intValue] == 0){ 
        cellLabel.text = [NSString stringWithFormat:@"%d",[cellLabel.text intValue] +0];
    }
    else{
        cellLabel.text = [NSString stringWithFormat:@"%d",[cellLabel.text intValue] -1];
    }
}

when i pressed the buttons, and added multiple cells, the buttons interfered with each other’s labels. So i added this line of code to each of the above methods. :

    cellLabel = (UILabel*)[sender superview];    

in hopes that it would fix the problem. But it actually added i believe the cells textLabel again. Here is a photo of what it looks like before and after i press one of the buttons with the new line added.

After:

any help with fixing the buttons interfering with each other cells UILabel’s please help!! 😀 Thanks

set tag to cell whet you cnfigurating it:
in my table I have some sections and some cells in every section. So, cells from first (0) section has tag 0…9999. from second – 10000…19999 adn so on. I mean tag of cell = 10000*number of section PLUS number of raw of this cell in ths section. then, to calculate what exacly is ths cell, I see how many 10000 tag has, to calculate from what sectiont it is, and how many >10000 tag has to calculate from what raw it is. So, I have section and raw from my table view.

cell.contentView.tag = indexPath.row+10000*indexPath.section; //or any you like
[cell.contentView addSubview:button]; //adding your button

then, in button’s callback:

int row=0;
int section=0;
long tag = [sender superview].tag;
NSLog(@"tag: %ld", tag);
for (int i = 0; i<[data count]; i++) {
    if (tag>=10000) 
    {
        tag-=10000;
        section++;
    }
    else i = [data count];
}
row = tag;

NSIndexPath *indexPath = [[NSIndexPath alloc] initWithIndex:section];
indexPath = [indexPath indexPathByAddingIndex:row];
[tableView cellForRowAtIndexPath:indexPath];

now, you have full access to your cell. use calculated raw and section ta get access to cell.
