How to know the indexPath/row on button click of Tableview cell in a UITableView? [duplicate]

Question

I created a TableView having a custom UITableViewCell. A button is associated with each row of tableview. Now I want to know the row number on click of a button, so that I would know that of which row button has been clicked. I have given a try to few things found on stack but nothing is working.

I have tried this code -:

-(void)button1Tapped:(id)sender
{
UIButton *senderButton = (UIButton *)sender;
UITableViewCell *buttonCell = (UITableViewCell *)[senderButton superview];
UITableView* table = (UITableView *)[buttonCell superview];
NSIndexPath* pathOfTheCell = [table indexPathForCell:buttonCell];
NSInteger rowOfTheCell = [pathOfTheCell row];
NSLog(@"rowofthecell %d", rowOfTheCell);
}

But this is also not working.

Thanks for helping me out.

Answer 1

try with this

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

        static NSString *CellIdentifier = @"Cell";

        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
            cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
            [[cell contentView] setBackgroundColor:[UIColor clearColor]];
            [[cell backgroundView] setBackgroundColor:[UIColor clearColor]];
             [cell.Mybutton addTarget:self action:@selector(btnCommentClick:) forControlEvents:UIControlEventTouchUpInside];
        }
         cell.Mybutton.tag=indexPath.row;
    }

    -(void)btnCommentClick:(id)sender
    {
            UIButton *senderButton = (UIButton *)sender;  
            NSLog(@"current Row=%d",senderButton.tag);
            NSIndexPath *path = [NSIndexPath indexPathForRow:senderButton.tag inSection:0];
    }

The best way to know which row of tableView is clicked is by setting tag value of cell button in cellForRowAtIndexPath method while using custom cell.
