You should do this in you viewDidload

- (void)viewDidLoad
{
    //Start Activity Indicator View
    indicatorView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    indicatorView.frame = CGRectMake(40.0, 20.0, 60.0, 60.0);
    indicatorView.center = self.view.center;
    [self.view addSubview:indicatorView];
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
    [indicatorView startAnimating];

    [self performSelectorInBackground:@selector(loadscroll) withObject:self];
}

Note: "performSelectorInBackground" will show you an activity indicator on the view and your loadScroll method will fetch all data from internet and do other work.

-(void)loadscroll
{
    //Your Scroll View 
        //Your other Data Manipulation even from internet
        //When data is fetched display it 
       [self removeActivityIndicator]; //To stop activity Indicator       
}

- (void)removeActivityIndicator
{
       [indicatorView stopAnimating];
}
