you create button assign

set button tag as a index of tableView cell.

[editButton setTag:indexPath.row];

in button

-(IBAction)editButtonAction:(id)sender
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:[sender tag] inSection:0]];

    NSLog(@"Selected Cell is: %@",cell);
    NSLog(@"Selected row is: %d",[sender tag]);
}

Actually the code works fine..Which row you selected for testing?is it 0? Try logging both rows and section.

Also check the outlet of table connected?and if the reference changed anywhere for that outlet

Otherwise the code runs fine for me

    NSLog(@"Row: %d\n ,Section :%d",indexPath.row,indexPath.section);;

In this method..

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

add this line:

  button.tag = indexPath.row;

And in this button action ,

 -(IBAction)editButtonAction:(id)sender

add this line:

int row = [sender tag];

alternative solution:

.
.
editButton.tag = indexPath.row;
[editButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[editButton addTarget:self action:@selector(editButtonAction:) forControlEvents:UIControlEventTouchUpInside];
.
.

-(IBAction)editButtonAction:(id)sender{
UIButton *btn = (UIButton*) sender;
NSLog(@"Selected row is: %d",btn.tag);
}
