receiver type 'AppDelegate' for instance message does not declare a method with selector ERROR

Can't seem to nail this issue here. Any idea what needs to be changed? I'm using Xcode 4.2.

Error: AppDelegate.m:23:6: error: receiver type 'AppDelegate' for instance message does not declare a method with selector 'setupHUD' [4]

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor = [UIColor whiteColor];

    LoginViewController *loginVC = [[LoginViewController alloc] init];
    UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:loginVC];
    navCon.navigationBarHidden = YES;
    self.window.rootViewController = navCon;
    [self setupHUD];

    [self.window makeKeyAndVisible];
    return YES;
}


- (void) setupHUD
{
    //setup progress hud
    self.HUD = [[MBProgressHUD alloc] initWithFrame:self.window.bounds];
    [self.window addSubview:self.HUD];
    self.HUD.dimBackground = YES;
    self.HUD.minSize = CGSizeMake(150.f, 150.f);
    self.HUD.delegate = self;
    self.HUD.isCancelButtonAdded = YES;
    self.HUD.labelText = @"Loading";
}

Prior to Xcode 4.3, you need to forward declare methods called within the same @implementation block, so make sure to add the declaration of setupHUD to either the class extension (the list of declarations inside AppDelegate.m that starts with @interface AppDelegate ()), or the @interface block in AppDelegate.h.

For example, in AppDelegate.m:

@interface AppDelegate ()
// Other declarations...
- (void)setupHUD;
@end

Or in AppDelegate.h:

@interface AppDelegate : NSObject <UIApplicationDelegate>
// Other declarations
- (void)setupHUD;
@end
