Calling (deleteRowsAtIndexPaths) outside (commitEditingStyle) in Objective-C for iPhone

Question

I have a custom UITableViewCellone in which two custom ones are added UIButton. On one of these buttons, I want to remove the cell row from myMethod().

The method is called addTarget:@selector(myMethod:)inside cellForRowAtIndexPath:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    ...
    cell.acceptButton.tag = indexPath.row;
    [cell.contentView addSubview:acceptButton];

    [cell.acceptButton addTarget:self action:@selector(myMethod:) forControlEvents:UIControlEventTouchUpInside];
}

This works, the actual method is called successfully.

- (void)myMethod:(id)sender {
   NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; //works fine (correct indexPath is returned)
   friendsArray removeObjectAtIndex:indexPath.row]; //works fine (correct indexPath.row is returned and the object is removed from the array)
   [tv deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; //throws error below
}

Error:

I usually did this when deleting a row inside a cell. This works great:

- (void)tableView:(UITableView *)tableview commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
 if(editingStyle == UITableViewCellEditingStyleDelete) {
  //Delete the object from the friends array and the table.
  [friendsArray removeObjectAtIndex:indexPath.row];
  [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
 }
}

Answer 1

if you use uibutton for each cell or more than one cell and set the same selector than the best option is to recognize the cell using tags.

, ( , , -, ). , accessView . . tableView:cellForRowAtIndexPath:
