Making custom segue

In developing iOS application, have you wanted to make your own cutomized segue? UIKit provides bare segues such as push, modal, popover and replace. These are useful in any situations. But sometimes I want to make my own transition. So, I wrote down some tips for making your own custom animation used by segue.

Make custom segue class

In Xcode, add new files. The name of this class, anything is OK. But you have to set super class UIStoryboardSegue. Otherwise storyboard cannot find this custom class subsequently.


In this case, I named FlipSegue

#import <UIKit/UIKit.h>

@interface FlipSegue : UIStoryboardSegue


And write animations like below.

#import "FlipSegue.h"

@implementation FlipSegue

- (void)perform {
    UIViewController *sourceController = (UIViewController*)self.sourceViewController;
    UIViewController *destinationController = (UIViewController*)self.destinationViewController;

    CATransition *transition = [CATransition animation];
    transition.duration = 0.4;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

    // Set transition animation type
    transition.type = kCATransitionFade;
    // Set transition animation subtype
    transition.subtype = kCATransitionFromTop;
    // Change animation
    [sourceController.navigationController.view.layer addAnimation:transition forKey:@"mytransition"];
    // Transition 
    [sourceController.navigationController pushViewController:destinationController animated:NO];



When this segue is called, these animation settings are executed automatically. If you want to change animation, type and subtype is the core of how the animation moves. These presets are documented in here Please see official document for detail. And then we’ll use this segue on storyboard.

Make segue with story board

You need to draw your custom segue on storyboard.


You can see flip, when you drag the arrow of segue on storyboard. This is your custom FlipSegue. So choose this segue. And run!! Pusing source button of flip segue, your will see your custom animated transition.
