Are present, then try this out:
if ([self respondsToSelector: @ selector (presentingViewController)]) {
[Self.presentingViewController.presentingViewController dismissModalViewControllerAnimated: YES];
}
else {
[Self.parentViewController.parentViewController dismissModalViewControllerAnimated: YES];
}
