didSelectRowAtIndexPath is not invoked to UIButton of cellForRowAtIndex

Question

I know that there are many duplicates here regarding this question but my requirement is that I added 2 UIButtons on one cell and both the buttons will open two different views. If I set the property userInteractionEnabled to YES, then it will not pic the 'finalID' from didSelectRowAtIndexPath from the below code.

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

    if(tableView == self.tableViewProject){
        static NSString *cellId = @"attachmentCellId";
        attachmentCell *cell = (attachmentCell *)[self.tableViewProject dequeueReusableCellWithIdentifier:cellId];
        if(!cell)
        {
            if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
            {
                NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"attachmentCell" owner:self options:Nil];
                for(id object in nib)
                {
                    if([object isKindOfClass:[attachmentCell class]])
                    {
                        cell = (attachmentCell *)object;
                        break;
                    }

                }
                UIButton *button;
                button = [[UIButton alloc] initWithFrame:CGRectMake(162, 0, 75, 53)];
                [button addTarget:self action:@selector(buttonClicked) forControlEvents:UIControlEventTouchUpInside];
                button.userInteractionEnabled = YES;
//button.userInteractionEnabled = NO;
                [cell.contentView addSubview:button];

                UIButton *buttonAttach = [[UIButton alloc] initWithFrame:CGRectMake(245, 0, 75, 53)];
                [buttonAttach addTarget:self action:@selector(buttonAttachClicked) forControlEvents:UIControlEventTouchUpInside];


                buttonAttach.userInteractionEnabled = YES;
//buttonAttach.userInteractionEnabled = NO;
                [cell.contentView addSubview:buttonAttach];

                cell = [nib objectAtIndex:0];
                SaveAttachment *attach = [array objectAtIndex:indexPath.row];
                cell.name.text = attach.name;
                cell.list.text = [NSString stringWithFormat:@"%d", attach.list];
                cell.attachment.text = [NSString stringWithFormat:@"%d", attach.attachment];
                cell.date.text = attach.date;
            }
    return cell;
    }

And my DidSelectRowAtIndexPath is

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
     NSLog(@"Array == %@", anotherTempArray);

        NSString *finalId = [NSString stringWithFormat:@"%@", [anotherTempArray objectAtIndex:indexPath.row]];
        NSLog(@"final id for selected row = %@", finalId);
        NSUserDefaults *defaultForFinalId = [NSUserDefaults standardUserDefaults];
        NSString *setFinalId = finalId;
        [defaultForFinalId setObject:setFinalId forKey:@"SETFINALID"];

    if(tableView == self.tableViewProject)
    {

        [self buttonClicked];
        //[self viewDidLoadForList];

    }
    if(tableView == self.tableViewAttachmentList)
    {


        [self buttonAttachClicked];

    }
}

Answer 1

If you want to call the selector of UIButton inside cell, then what you dont need to use didSelectRowAtIndexPath method.

What you did was correct upto adding handler to UIButton. Now, remove your didSelectRowAtIndexPath code to button's click handler. Here is how you can get indexPath from the button click handler.

- (void)buttonClicked:(UIButton *)sender {

    UITableViewCell *cell = (UITableViewCell*)sender.superview.superview; //Since you are adding to cell.contentView, navigate two levels to get cell object
    NSIndexPath *indexPath = [tableView indexPathForCell:cell];

    // Now you can do the code you put in didSelectRow here.
}

Hope this helps.

change your code for button selector

[button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside]; //add colon in selector buttonClicked


[buttonAttach addTarget:self action:@selector(buttonAttachClicked:) forControlEvents:UIControlEventTouchUpInside]; //add colon in selector buttonAttachClicked
