How to write actions for UIButton placed in every cell of tableview?

Question

i am having a custom tableview cell where i have a UIButton. i want to write action for every button placed in tableview cell. tell me how to do it. i have tried using tag but its not working as cellForRowAtIndexPath load all the cell at once so its overwriting the tag number. please tell me how to do it. following code i am using

if(indexPath.row == 0){[cell.viewButton addTarget:self action:@selector(playMovie) forControlEvents:UIControlEventTouchUpInside];
       cell.viewButton.tag = 1;
    }
    else {
        [cell.viewButton addTarget:self action:@selector(playMovie) forControlEvents:UIControlEventTouchUpInside];
        cell.viewButton.tag = 2;
    }
return cell;

enter image description here

do you want to do different action for different button or same action for all button — Yohan, Dec 11 '13 at 11:43
different action for different buttons and i dont wanna use didSelectRowAtIndexPath. — Deepak Carpenter, Dec 11 '13 at 11:44
@jrturton its not duplicate. PFP in my question i have updated. i am not using IBOutlet its just a UIButton. — Deepak Carpenter, Dec 11 '13 at 11:57
It _is_ a duplicate. It makes no difference if you are using an outlet or not. You want to know which cell the button was in when it was clicked, right? — jrturton, Dec 11 '13 at 12:04

Pass the instance of button also with @selector

[cell.viewButton addTarget:self action:@selector(playMovie:) forControlEvents:UIControlEventTouchUpInside]
cell.viewButton.tag = indexpath.row;

And then implement the button click method like this

-(void)playMovie:(UIButton *)sender{

  if(sender.tag == 0){
  NSLog(@"button at first cell");

  }else if (sender.tag  == 1){
  NSLog(@"button at first cell");
  }
  // SO on.......
}

You can give button tag to your button then you can identified that button in its method.

cell.btn.tag = indexPath.row+1;

and you can get that in its click event

-(void)btnOnClick:(id)sender
{
UIButton *btnTag = (UIButton *)sender.tag;
if(btn.tag == 1)
{
}
}

Why do you add +1? Is their any special reason? – Mani Dec 11 '13 at 11:56
in tableview indexPath.row is starting with 0 thats why add +1 so it is start with +1. Nothing else. – Maulik Kundaliya Dec 11 '13 at 12:28
Ya I can understand what you've done. But Even if you don't add +1, code should work.. that's why asked.. Happy coding :) – Mani Dec 11 '13 at 12:31
Ya i know then you compare tag with 0 in click event... – Maulik Kundaliya Dec 11 '13 at 12:33

No need to add target for every rows, Do something like this :

if(indexPath.row == 0){
       cell.viewButton.tag = 100;
    }
    else {
        cell.viewButton.tag = 101;
    }
[cell.viewButton addTarget:self action:@selector(playMovie:) forControlEvents:UIControlEventTouchUpInside];
return cell;


-(IBAction)playMovie:(id)sender{
if(sender.tag == 100){
// Do your Stuff..
}else if(....).....

}
