How to change speed of segue between ViewControllers

Question

Is it possible to control segue speed?

I have checked the documentation but there is no given method by Apple.

But I am more looking for ideas to hack in and change lower level code to make segueing in slow motion.

Below code is of custom segue, and you can set duration of transition in code.

- (void)perform 
{
    UIViewController *src = (UIViewController *) self.sourceViewController;
    UIViewController *dst = (UIViewController *) self.destinationViewController;
    [UIView transitionFromView:src.view
                        toView:dst.view
                      duration:3.0
                       options:UIViewAnimationOptionTransitionFlipFromLeft
                    completion:NULL];

}

Sample project is here in GitHub:https://github.com/weed/p120805_CustomSegue

You can download and just run it. I wish this is help for you.

to prevent zombies creation i think better to do use subview add/remove as well:

- (void)perform
{
    UIView *src = ((UIViewController *) self.sourceViewController).view;
    UIView *dst = ((UIViewController *) self.destinationViewController).view;

    UIWindow *window = [[[UIApplication sharedApplication] delegate] window];
    [window insertSubview:dst aboveSubview:src];

    [UIView transitionFromView:src
                        toView:dst
                      duration:1.5
                       options:UIViewAnimationOptionTransitionCrossDissolve
                    completion:^(BOOL finished){
                        [src removeFromSuperview];
                        window.rootViewController = self.destinationViewController;
                    }];
}

this is if you are not using navigation controller!
