Automatically cell selected UITableView - ios

Question

My UITableView opens via PopOverViewController , so How can I load one of these cells automatically after app did load ,
the cell selecting process on MainViewController
- (void)setDetailItem:(id)newDetailItem {
if (detailItem != newDetailItem) {
[detailItem release];
detailItem = [newDetailItem retain];
//---update the view---
label.text = [detailItem description];
}
}
and cell selecting in TableViewController :
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
myAppDelegate *appDelegate =
[[UIApplication sharedApplication] delegate];
appDelegate.viewController.detailItem = [list objectAtIndex:indexPath.row];
}
I use this code in TableViewController but does not work ! It means after press the the popOver button the code just highlight the cell !!
[myTableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:0];
I used above code in different methods like viewDidAppear , viewWillAppear and didSelectRowAtIndexPath and ...
Thank you

When you call selectRowAtIndexPath:animated:scrollPosition:, tableView:didSelectRowAtIndexPath: is not called on the delegate.
From the selectRowAtIndexPath:animated:scrollPosition: reference:
Calling this method does not cause the delegate to receive a
tableView:willSelectRowAtIndexPath: or
tableView:didSelectRowAtIndexPath: message, nor will it send
UITableViewSelectionDidChangeNotification notifications to observers.
So, instead of just calling selectRowAtIndexPath:animated:scrollPosition::
[myTableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:0];
you could call the delegate methods manually:
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
if ([myTableView.delegate respondsToSelector:#selector(tableView:willSelectRowAtIndexPath:)]) {
[myTableView.delegate tableView:self.tableView willSelectRowAtIndexPath:indexPath];
}
[myTableView selectRowAtIndexPath:indexPath animated:YES scrollPosition: UITableViewScrollPositionNone];
if ([myTableView.delegate respondsToSelector:#selector(tableView:didSelectRowAtIndexPath:)]) {
[myTableView.delegate tableView:self.tableView didSelectRowAtIndexPath:indexPath];
}
