DropDown ViewController transition (aka iOS 8 Mail app swipeable VC) in 200 strings

#VCTransition The heart of this project is GITransition object, it adopts UIViewControllerAnimatedTransitioning and UIGestureRecognizerDelegate protocol, which allows you to have one view controller at the bottom, and on the same time keeping your main navigation separate. This was inspired by the iOS 8 emails implementation where you can have your new email open at the bottom while still viewing all your old emails above it.

#Demo

#Example

    transitionManager = [[GITransition alloc] init];
    self.transitioningDelegate = transitionManager;
    
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    controller = [storyboard instantiateViewControllerWithIdentifier:@"vcAddNewGoal"];
    controller.transitioningDelegate = transitionManager;
    controller.modalPresentationStyle = UIModalPresentationCustom;
    controller.transitionManager = transitionManager;

- (IBAction)show:(id)sender {
    [self presentViewController:controller animated:YES completion:nil];
}

#Usage Copy GITransition folder into your project.

vctransition's Issues

Presenting a view controller above VCTransition controller causes parent view to slide up

Hi,

This is a great bit of code, makes for a much nicer view controller transition. The only problem I am having is that if I open a view controller with GITransition and then open another view controller on top of that, the GITransition view controller slides to the top (it doesn't stay at the ~80% y axis position that it originally opened to). For example:

You open a "settings" view controller with GITransition. The settings view has a few different buttons, one which includes a "Send Feedback" email button. When the button is pressed, it opens Apple's Mail composer view above the settings view. That's all fine, however when you then dismiss the main composer view, you notice that the settings view has been positioned higher than it was before - in other words it has moved up and is taking up the entire y axis (which is not where it was before the mail composer view was opened).

Is there anyway to fix this?

Thanks for your time, Dan.
