You can try this give a tag to your button (make sure it is unique).

Let say your button has tag 45; and you have made it in your table view.

Now in another method you want to use your that button like this:-

-(void)deletePostMethod
{
    UIButton *button=(UIButton *)[self.view viewWithTag:49];
    [button setBackgroundColor:[UIColor redColor]];
    NSLog(@"button=%@",button);
}

Edited Answer:-

- (UITableViewCell *)tableView:(UITableView *)tablefirst cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    // I  have added a button in my table view in first row
    if (indexPath.row==0) {
        UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom];
        [btn setFrame:CGRectMake(0, 0, 40, 30)];
        [btn addTarget:self action:@selector(deletePostMethod) forControlEvents:UIControlEventTouchUpInside];
        btn.tag=579;
        [cell.contentView addSubview:btn];
    }
        return cell;
}

On that button click method

-(void)deletePostMethod
{
    UIButton *button=(UIButton *)[self.view viewWithTag:579];
    [button setBackgroundColor:[UIColor redColor]];
    NSLog(@"button=%@",button);
}

After clicking this button button background color set to red.
