Back to target quit vc animatable.

pod 'TargetQuitViewController' to install.

#import "UIViewController+TargetQuitViewController.h"

UIViewController *tmpVC = [what vc you want to back to];

Then self.targetQuitViewController = tmpVC;

[self backToTargetQuitViewController];

And it will back to tmpVC from self animatable, ignore self's parentVC or presentingVC.
