accessing array from application delegate

i have declared 1 array in application delegate 

@property(strong,nonatomic)NSMutableArray *books;

i have added objects to this array in XMLParser.m 

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {

    if([elementName isEqualToString:@"Books"])
        return;
    NSLog(@"i m in didEndElement");

    if([elementName isEqualToString:@"Book"]) {
        [appDelegate.books addObject:aBook]; //here i have added objects to array

        [aBook release];
        aBook = nil;

        NSLog(@"books=%@",appDelegate.books);
    }
    else 
        [aBook setValue:currentElementValue forKey:elementName];

    [currentElementValue release];
    currentElementValue = nil;
}

i have declared this array in XMLParser.h like this 

@interface XMLParser : NSObject {
    NSMutableString *currentElementValue;

    AppDelegate *appDelegate;
    Book *aBook; 
}

now i have to access this array in BooksDetailViewController.m , how do i access this array. in short how i can access array from application delegate into BooksDetailViewController

First of all you should have to alloc and init your array, then You can add objects in it.

You should have to create AppDelegate instance in your BooksDetailViewController like this,

in .h file

AppDelegate *appDelegate;

and in .m file

appDelegate = [[UIApplication sharedApplication]delegate];

Now you can access your array like this,

appDelegate.books
