This works great for nested elements as well of course:

// Get the JSON feed from site
myRawJson = [[NSString alloc] initWithContentsOfURL:[NSURL 
            URLWithString:@"http://yoursite.com/mobile_list.json"] 
            encoding:NSUTF8StringEncoding error:nil];

// Make the content something we can use in fast enumeration
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSDictionary * myParsedJson = [parser objectWithString:myRawJson error:NULL];
[myRawJson release];
allLetterContents = [myParsedJson objectForKey:@"nodes"];

    // Create arrays just for the title and Nid items
    self.contentTitleArray = [[NSMutableArray alloc]init];

    for (NSMutableDictionary * key in myArr) {
        NSDictionary *node = [key objectForKey:@"node"];
        NSMutableString *savedContentTitle = [node objectForKey:@"title"];        

        // Add each Title and Nid to specific arrays
        //[self.contentTitleArray addObject:contentTitle];

        //change each item with & to &
        [self.contentTitleArray addObject:[[savedContentTitle      
                                stringByReplacingOccurrencesOfString:@"&" 
                                withString:@"&"] 
                                mutableCopy]];

    }

The code below, as shown in the use-case above might be helpful.

[self.contentTitleArray addObject:[[contentTitle 
                                    stringByReplacingOccurrencesOfString:@"&" 
                                    withString:@"&"] 
                                    mutableCopy]];
