@interface AppAppDelegate : NSObject <UIApplicationDelegate,MBProgressHUDDelegate,ProductListDelegate,NSXMLParserDelegate,UIPopoverControllerDelegate,UIAlertViewDelegate,UIPrintInteractionControllerDelegate,UIWebViewDelegate>

(Add Delegate Methods).

@property (nonatomic,retain) MBProgressHUD* HUD;

AppDelegate.M
