I have a like button on a cell, and the number of likes being shown beside it.
I have created all the cells in cellForRowAtIndexPath, and I have tagged each cell with it's indexPath. Now, when somebody taps the "like" button, I want to show the updated number without having to reload the entire table.

For the sake of simplicity, I'll show the barebones of my code:

```
-()cellForRowAtIndexPath{
...

cell.Plus.tag = indexPath.row;
[cell.Plus addTarget:self action:@selector(plusBtnClick:) forControlEvents:UIControlEventTouchUpInside];

...
}

-(void) plusBtnClick:(id)sender{
//update the number
}

```
