tableview scrollRectToVisible CGRectMake 0  0  1  1  animated NO     This will take your tableview to the first row

Use  tableView scrollToRowAtIndexPath indexPath atScrollPosition scrollPosition animated YES    Scrolls the receiver until a row identified by index path is at a particular location on the screen   And  scrollToNearestSelectedRowAtScrollPosition animated    Scrolls the table view so that the selected row nearest to a specified position in the table view is at that position

It is worth noting that if you use the setContentOffset approach  it may cause your table view collection view to jump a little  I would honestly try to go about this another way  A recommendation is to use the scroll view delegate methods you are given for free

finally I found    it will work nice when table displays only 3 rows    if rows are more change should be accordingly     -  NSInteger numberOfSectionsInTableView  UITableView   tableView           return 1         Customize the number of rows in the table view  -  NSInteger tableView  UITableView   tableView   numberOfRowsInSection  NSInteger section         return 30     -  UITableViewCell   tableView  UITableView   tableView           cellForRowAtIndexPath  NSIndexPath   indexPath       static NSString  CellIdentifier     Cell        UITableViewCell  cell    tableView dequeueReusableCellWithIdentifier CellIdentifier        if  cell    nil                         cell      UITableViewCell alloc  initWithStyle UITableViewCellStyleDefault                                            reuseIdentifier CellIdentifier  autorelease                 Configure the cell      cell textLabel text   NSString stringWithFormat   Hello roe no   d   indexPath row         return cell     -  void tableView  UITableView   tableView didSelectRowAtIndexPath  NSIndexPath   indexPath       UITableViewCell   theCell    UITableViewCell    tableView                                                    cellForRowAtIndexPath indexPath        CGPoint tableViewCenter    tableView contentOffset       tableViewCenter y    myTable frame size height 2        tableView setContentOffset CGPointMake 0 theCell center y-65  animated YES        tableView reloadData

it should work using -  void scrollToRowAtIndexPath  NSIndexPath   indexPath atScrollPosition  UITableViewScrollPosition scrollPosition animated  BOOL animated using it this way   NSIndexPath  indexPath    NSIndexPath indexPathForRow 0 inSection 0    yourTableView scrollToRowAtIndexPath indexPath                       atScrollPosition UITableViewScrollPositionTop                               animated YES     atScrollPosition could take any of these values   typedef enum   UITableViewScrollPositionNone  UITableViewScrollPositionTop  UITableViewScrollPositionMiddle  UITableViewScrollPositionBottom   UITableViewScrollPosition    I hope this helps you  Cheers
