- (void)viewDidLoad {
  UIAlertView* _alertView = [[UIAlertView alloc] initWithTitle:@"Loading Chapters..."
                                                             message:@"\n"
                                                            delegate:self
                                                   cancelButtonTitle:nil
                                                   otherButtonTitles:nil];

        UIActivityIndicatorView *spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
        // UIProgressView *loading=[[UIProgressView alloc]initWithProgressViewStyle:UIProgressViewStyleBar];

        // loading.center=CGPointMake(50,100);
        spinner.center = CGPointMake(139.5, 75.5); // .5 so it doesn't blur

        [_alertView addSubview:spinner];
        // [_alertView addSubview:loading];

        [spinner startAnimating];
        [_alertView show];
          if(loadingProgressBar+1>[sharedManager.spineArray count]) {

            [_alertView dismissWithClickedButtonIndex:0 animated:YES];
        }


    [_alertView dismissWithClickedButtonIndex:0 animated:YES];
      [super viewDidLoad];

    if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))

    {
        webView.frame=CGRectMake(0,0,480,315);

          BottomBar.frame=CGRectMake(0,260, CGRectGetWidth(self.view.bounds),41);

        //NSLog(@"%f%f",CGRectGetHeight(self.view.bounds), CGRectGetWidth(self.view.bounds));

    }
    }
