De lo que puedo recopilar no es posible usar una animación de View Controller como una transición Segue. Actualmente tengo un conjunto de animaciones de View Controller en un proyecto existente que crea transiciones animadas entre View Controllers. Por ejemplo:

Animación modal archivo .h:

//
//  MVModalDismissAnimation.h
//

#import "MVBaseAnimation.h"

@interface MVModalAnimation : MVBaseAnimation

@end

Animación modal archivo .m:

//
//  MVModalDismissAnimation.m
//

#import "MVModalAnimation.h"

@implementation MVModalAnimation {
UIView *_coverView;
NSArray *_constraints;
}

#pragma mark - Animated Transitioning

-(void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext {
//The view controller's view that is presenting the modal view
UIView *containerView = [transitionContext containerView];

if (self.type == AnimationTypePresent) {
    //The modal view itself
    UIView *modalView = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey].view;

    //View to darken the area behind the modal view
    if (!_coverView) {
        _coverView = [[UIView alloc] initWithFrame:containerView.frame];
        _coverView.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.6];
        _coverView.alpha = 0.0;
    } else _coverView.frame = containerView.frame;
    [containerView addSubview:_coverView];

    //Using autolayout to position the modal view
    modalView.translatesAutoresizingMaskIntoConstraints = NO;
    [containerView addSubview:modalView];
    NSDictionary *views = NSDictionaryOfVariableBindings(containerView, modalView);
    _constraints = [[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-30-[modalView]-30-|" options:0 metrics:nil views:views] arrayByAddingObjectsFromArray:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-30-[modalView]-30-|" options:0 metrics:nil views:views]];
    [containerView addConstraints:_constraints];

    //Move off of the screen so we can slide it up
    CGRect endFrame = modalView.frame;
    modalView.frame = CGRectMake(endFrame.origin.x, containerView.frame.size.height, endFrame.size.width, endFrame.size.height);
    [containerView bringSubviewToFront:modalView];

    //Animate using spring animation
    [UIView animateWithDuration:[self transitionDuration:transitionContext] delay:0.0 usingSpringWithDamping:0.8 initialSpringVelocity:1.0 options:0 animations:^{
        modalView.frame = endFrame;
        _coverView.alpha = 1.0;
    } completion:^(BOOL finished) {
        [transitionContext completeTransition:YES];
    }];
} else if (self.type == AnimationTypeDismiss) {
    //The modal view itself
    UIView *modalView = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey].view;

    //Grab a snapshot of the modal view for animating
    UIView *snapshot = [modalView snapshotViewAfterScreenUpdates:NO];
    snapshot.frame = modalView.frame;
    [containerView addSubview:snapshot];
    [containerView bringSubviewToFront:snapshot];
    [modalView removeFromSuperview];

    //Set the snapshot's anchor point for CG transform
    CGRect originalFrame = snapshot.frame;
    snapshot.layer.anchorPoint = CGPointMake(0.0, 1.0);
    snapshot.frame = originalFrame;

    //Animate using keyframe animation
    [UIView animateKeyframesWithDuration:[self transitionDuration:transitionContext] delay:0.0 options:0 animations:^{
        [UIView addKeyframeWithRelativeStartTime:0.0 relativeDuration:0.15 animations:^{
            //90 degrees (clockwise)
            snapshot.transform = CGAffineTransformMakeRotation(M_PI * -1.5);
        }];
        [UIView addKeyframeWithRelativeStartTime:0.15 relativeDuration:0.10 animations:^{
            //180 degrees
            snapshot.transform = CGAffineTransformMakeRotation(M_PI * 1.0);
        }];
        [UIView addKeyframeWithRelativeStartTime:0.25 relativeDuration:0.20 animations:^{
            //Swing past, ~225 degrees
            snapshot.transform = CGAffineTransformMakeRotation(M_PI * 1.3);
        }];
        [UIView addKeyframeWithRelativeStartTime:0.45 relativeDuration:0.20 animations:^{
            //Swing back, ~140 degrees
            snapshot.transform = CGAffineTransformMakeRotation(M_PI * 0.8);
        }];
        [UIView addKeyframeWithRelativeStartTime:0.65 relativeDuration:0.35 animations:^{
            //Spin and fall off the corner
            //Fade out the cover view since it is the last step
            CGAffineTransform shift = CGAffineTransformMakeTranslation(180.0, 0.0);
            CGAffineTransform rotate = CGAffineTransformMakeRotation(M_PI * 0.3);
            snapshot.transform = CGAffineTransformConcat(shift, rotate);
            _coverView.alpha = 0.0;
        }];
    } completion:^(BOOL finished) {
        [_coverView removeFromSuperview];
        [containerView removeConstraints:_constraints];
        [transitionContext completeTransition:YES];
    }];
}
}

-(NSTimeInterval)transitionDuration:(id<UIViewControllerContextTransitioning>)transitionContext {
if (self.type == AnimationTypePresent) return 1.0;
else if (self.type == AnimationTypeDismiss) return 1.75;
else return [super transitionDuration:transitionContext];
}

@end

Lo anterior desliza un controlador de vista modal hacia arriba desde la parte inferior.

Ahora me gustaría convertir esto para trabajar con guiones gráficos y segues.

Tengo otros cuatro tipos de animación que quiero convertir, ¿hay una forma sencilla de hacer que la clase anterior funcione con transiciones segue?
