Description Vincent Bellet 2013-09-19 12:43:20 UTC
iOS 7 introduced new API for managing custom transition between UIViewController.

While it work well, the APi choice is badly thought for the UIViewControllerTransitioningDelegate delegate :

public override IUIViewControllerAnimatedTransitioning PresentingController (UIViewController presented, UIViewController presenting, UIViewController source)


			public override IUIViewControllerAnimatedTransitioning GetAnimationControllerForDismissedController (UIViewController dismissed)


there is no CONSISTENCY between the two! (one have get and the other doesn't)

Proposal :

Make it balance and consistent so you either go for two gets or none!

On a general note and I know that I will go outside the code of bug report but changing cocoa API is bad, cause all objc resources like tutorial and tips are harder to translate when API is not the same.
Comment 1 Vincent Bellet 2013-09-19 12:47:25 UTC
to be more clear here the proposal API change :

either :

public virtual IUIViewControllerAnimatedTransitioning GetAnimationControllerForPresentingController (UIViewController presented, UIViewController presenting, UIViewController source)


public virtual IUIViewControllerAnimatedTransitioning AnimationControllerForPresentingController (UIViewController presented, UIViewController presenting, UIViewController source)

(this one have my preference)
Comment 2 Rolf Bjarne Kvinge [MSFT] 2014-11-04 05:56:51 UTC
Fixed for the Unified API.

It ended up being called GetAnimationControllerForPresentedController to match the rest of the members.
