Question

On my view, I used to have few buttons and each button had an action associated with it.

    UIButton *testButton = [[UIButton alloc] initWithFrame:CGRectMake(120,300,90,90)];
    [testButton setBackgroundImage:[UIImage imageNamed:@"test.jpg"] forState:UIControlStateNormal];
    [testButton addTarget:self.view action:@selector(gotoProd:) forControlEvents:UIControlEventTouchUpInside];
    [testButton addt
    [scrollView testButton];

But now I am trying to replace all those buttons with the tableview with rows. I was able to populate the rows and I know one needs to use didSelectRowAtIndexPath for handling on select event of the cell. But how can I implement action:@selector(gotoProd:) in tableviews ?? Any help will be greatly appreciated.

The most straight-forward way would look like this:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

      switch (indexPath.row) {
        case 0:
            [self doRow0Action];
            break;
        case 1:
            [self doRow1Action];
            break;
        // etc...

        default:
            break;
    }
}

If you wanted to instead, you could initialize an array with SEL types:

[actionArray addObject:@selector(doRowNAction)];

then access it like this:

[self performSelector:[actionArray objectAtIndex:indexPath.row] withObject:nil];
