Question

I do the following:

myAppDelegate file

I’m parsing an xml file and set its content to NSMutableArray * catalogue, this way:

NSMutableArray * catalogue;
    NSMutableDictionary * item;

    NSString * currentElement;
    NSMutableString *currentName, *currentUrl;

---

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{     
    //NSLog(@"ended element: %@", elementName);
    if ([elementName isEqualToString:@"catalog"]) {
        // save values to an item, then store that item into the array...
        [item setObject:currentName forKey:@"name"];
        [item setObject:currentUrl forKey:@"url"];
        [catalogue addObject:[item copy]];
    }
    }

myUiViewController class

- (void)viewDidLoad
{
    [super viewDidLoad];
    nameCatalog = [myAudiAppDelegate sharedAppDelegate].catalogue;
    NSLog(@"noul sir format %@", nameCatalog);

}

This is what my nameCatalog looks like:

 {
    name = "Audi TT Coup\U00e9";
    url = "http://host_server/uploads/modeles_pdf/43_TT_Coupe_TT_Roadster_Catalogue_Tarifs_20110428.pdf";
},
    {
    name = "Audi TT Roadster";
    url = "http://host_server/uploads/modeles_pdf/42_TT_Coupe_TT_Roadster_Catalogue_Tarifs_20110428.pdf";
}

What I don’t know is…how do I get the name value from there to put it in a tableView?

This is my method:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }

    // Set up the cell...
    cell.text = [nameCatalog objectAtIndex:indexPath.row];
    return cell;
}

But I get the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary isEqualToString:]: unrecognized

How should I acces nameCatalog?Thanks

Following is the solution for you problem…

    cell.textLabel.text = [[nameCatalog objectAtIndex:indexPath.row] valueForKey:@"name"];

nameCatalog is your NSMutableArray. [nameCatalog objectAtIndex:indexPath.row] returns a NSMutableDictionary. And you have to get the value by using valueForKey from that.
