Meaning of Warning "while a presentation is in progress!"

When I am integarting the Instagram in my project. I am getting a

and after it i want to send it to Instagram But when I am sending
to Instagram by
delegate method
presentOptionsMenuFromRect:inView: animated:
like this

[documentInteractionController presentOptionsMenuFromRect:CGRectZero inView:self.view animated:YES];

The warning comes Warning: Attempt to present <_UIDocumentActivityViewController: 0x7584780> on while a presentation is in progress!

The application is not Crashing. But I am not getting the Problem. Why this warning comes and what It means. I searched on Internet and read questions about this but not got any answer. Help me !!

// Breaks
[viewController1 dismissViewControllerAnimated:YES completion:NULL];
[self presentViewController:viewController2 animated:YES completion:NULL];

// Does not break
[viewController1 dismissViewControllerAnimated:YES completion:^{
    [self presentViewController:viewController2 animated:YES completion:NULL];

Note the use of the completion handler in the second example above. It only presents viewController2 after viewController1 has been fully dismissed.
