"Problems with View1 path to View2."

pleasehelp · September 2011

hi friends,

hope you can help.

i have a string (customerName) in CustomersViewController (view 1).
now i just want to display in my CustomersViewDetailController (view 2)
the string (customerName) from CustomersViewController (view 1). this should be displayed in the section 0 of my tableview.

it must be something little but i don´t know how to do!?

in my CustomersViewController.m

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSInteger row = [indexPath row];
NSString *customerName = @"Name";
if (cusDetailViewController == nil) {
CustomersDetailViewController *aCustomerDetail = [[CustomersDetailViewController alloc] initWithNibName:@"CustomersDetailView" bundle:nil];
self.cusDetailViewController = aCustomerDetail;
[aCustomerDetail release];
}
CustomersDetailViewController *cusDetailViewController = [[CustomersDetailViewController alloc] initWithStyle:UITableViewStyleGrouped];
[self.navigationController pushViewController:cusDetailViewController animated:YES];
if(indexPath.section == 0)
{
<----Here I dont' t know what to do---->
}
[cusDetailViewController release];
cusDetailViewController = nil;
}

Hmm... well it looks like for one you are alloc/init CustomersDetailViewController two times.
Once here:


if (cusDetailViewController == nil) {
CustomersDetailViewController *aCustomerDetail = [[CustomersDetailViewController alloc] initWithNibName:@\"CustomersDetailView\" bundle:nil];
self.cusDetailViewController = aCustomerDetail;
[aCustomerDetail release];
}

and again here:


CustomersDetailViewController *cusDetailViewController = [[CustomersDetailViewController alloc] initWithStyle:UITableViewStyleGrouped];

You only need to do this once. If you are doing it twice just so you can indicate both to use your .xib and that you want the UIViewController to be of type UITableViewStyleGrouped, I would go with indicating the .xib file and set the style in interface builder. Also you should not set cusDetailViewController to nil in the method but in the dealloc method (unless you are using xcode 4, which does this for you).

Lastly, to set the cell.textLabel in cusDetailViewController, you need to pass "name" to this new viewController in some way (possibly NSUserDefaults) and then set it as the textLabel.text of the cell in either cellForRowAtIndexPath or willDisplayCell.

Howdy, Stranger!
