This action will happen in your didSelectRowAtIndexPath, when you will try to hide or show number of cell in a  section

first of all declare a global variable numberOfSectionInMoreInfo in .h file and in your viewDidLoad set suppose to numberOfSectionInMoreInfo = 4.

Now use following logic: 


 // More info link
        if(row == 3) {

            /*Logic: We are trying to hide/show the number of row into more information section */

            NSString *log= [NSString stringWithFormat:@"Number of section in more %i",numberOfSectionInMoreInfo];

            [objSpineCustomProtocol showAlertMessage:log];

            // Check if the number of rows are open or close in view
            if(numberOfSectionInMoreInfo > 4) {

                // close the more info toggle
                numberOfSectionInMoreInfo = 4;

            }else {

                // Open more info toggle
                numberOfSectionInMoreInfo = 9;

            }

            //reload this section
            [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:1] withRowAnimation:UITableViewRowAnimationFade];
