Adding a UIActivityIndicator ID to a Modal View (ELCimagepicker)

I added the ELCimagepicker (https://github.com/Fingertips/ELCImagePickerController) to my project and it works great, allowing the user to select multiple images for the slide show. But when you click "Save", there may be a long delay depending on how many photos have been added.

I am trying to add the UIActivityIndicator identifier when the user clicks “Save”, but has problems due to the presented modal view. I can call the method from the activity that ELCimagepicker represents (ELCImagePickerController), and this is activated by the action that handles the image picker view. But whenever I try to add to the view, it does not appear, since the modal is on top of the activity indicator.

I tried using the bringSubviewToFront method, I tried to add code directly to the imagepicker method file with [[self parentViewController] addSubView], but no luck.

Here is the last code I tried: (the indicator is declared in the .h file as a UIActivityIndicator * indicator)

 indicator = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
indicator.hidden=false;

[self.navigationController.view addSubview:self.indicator];
[self.navigationController.view bringSubviewToFront:self.indicator];

[indicator startAnimating];

if([delegate respondsToSelector:@selector(elcImagePickerController:showIndicator:)]) {
    [delegate performSelector:@selector(elcImagePickerController:showIndicator:) withObject:self withObject:@"test"];
}

I solved a problem like this

     activityIndicatorObject = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

     // Set Center Position for ActivityIndicator

     activityIndicatorObject.center = CGPointMake(150, 250);
     activityIndicatorObject.backgroundColor=[UIColor grayColor];

     // Add ActivityIndicator to your view
     [self.view addSubview:activityIndicatorObject];

     activityIndicatorObject.hidesWhenStopped=NO;

     [activityIndicatorObject startAnimating];
