How to manage UITableView + Dynamic Custom Cell(UIBUtton + UITextField + UIBUtton) Insertion?

I am having problem in managing UITableView. I 'm posting a screenshot here to briefly explain the problem. Image 1 shows the default View when First Time view Appears. When I tap on yellow button(Yellow Button is in a custom table section header view) I open an UIAlertView with table in it like shown in the image 2

. Then selecting any option I insert a custom cell with a button,textfield and another button. I have a mutable Array for each section so when I select an option I add that string into the corresponding section array and reloadtable.See image 3

. Now when I enter values in UITextfields the values replaced by another cells. See the two images below for understanding the problem. image 4

. Also when I delete a cell and insert a new the textfield is preloaded with previous value.

And here is the .m file implementation code for analyze the problem

#import "contactsViewController.h"
#import "textFieldCell.h"
#import "SBTableAlert.h"
#import "PhoneFieldCell.h"
#import "DHValidation.h"

#define kTextFieldTag 222
#define kTitleButtonTag 111
#define MAX_LENGTH 20
#define charecterLimit 13
#define PHONE_NUMBER @"0123456789+-"

@synthesize choiceList;
@synthesize labelHeaders;
@synthesize selectedIndexPath;
@synthesize aTable;

here is your answer http://www.icodeblog.com/2011/01/04/elctextfieldcell-a-useful-tableviewcell-for-forms/

u can also manually do some customization according to your app need

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

     [tableView reloadData];

  }
