Black background color on dismiss transition (Objective-C only)

[slxl]

func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    transition.transitionMode = .Dismiss
    transition.startingPoint = transitionButton.center
    transition.bubbleColor = transitionButton.backgroundColor!
    return transition
}

Demo project, tested on simulator iOS8.3/iOS8.4 and on iPhone 5s iOS8.4

[andreamazz]

Tested now, it's working fine. I did a fresh clone also, just to be sure.
Which version of Xcode are you using?

[slxl]

Version 6.4 (6E35b)

[andreamazz]

Yup, same version here, no issues.

[slxl]

What environment (iOS version, device/simulator) do you use?

[andreamazz]

8.4 on an iPhone 5s as you suggested above.

[slxl]

looks like I found, problem was with a setting for segue presentation (full screen instead of default in project), pardon, my fault

[andreamazz]

No problem 👍

[slxl]

thanks for tool!

[andreamazz]

👍

[slxl]

@andreamazz problem still persists (but in my project only), looks like its something similar to what google returns for "dismiss modal view controller black screen" request, still looking for solution :/

all presentation settings and stuff are (i hope) identical, the only significant difference is that im using your BubbleTransition.swift in objective-c project. But I think that shouldnt be a problem

[andreamazz]

Can you share the code or reproduce part of it in a stand alone project? I'll be happy to take a look at it.

[slxl]

Will try tmrw, thanks!

I found solution here:
http://www.raywenderlich.com/forums/viewtopic.php?f=2&t=18661

Add this code in prepareForSegue:

UIViewController *controller = segue.destinationViewController;

if (SYSTEM_VERSION_LESS_THAN(@"8.0")) {
} else {
    controller.modalPresentationStyle = UIModalPresentationOverCurrentContext;

}

@andreamazz Despite being slowpoke, but I'm responsible also :)

here is a template project with a same structure as mine original. Would be great if you' have a look whats wrong there. Thanks! )

[slxl]

@andreamazz had a time to look?

[andreamazz]

Not yet, sorry, I'll get around it this weekend.

[slxl]

@andreamazz appreciate this, thanks! I tried few approaches already, we could discuss in skype if you want (id: slxl.ru)

[andreamazz]

Well, I'm confused.
This is the view hierarchy in the sample:

You can see the starting view.
This is the hierarchy of your sample:

The starting view is not in the hierarchy, that's why you see a black screen during the transition.
Can't figure out why...

[andreamazz]

Ok, I started a new project, dropped in the animation, and I have the same issue. wth...

[andreamazz]

The same sample written in Swift works fine. Awesome.

@andreamazz good news everyone!

somehow in both (yours and mine) projects there was

controller.modalTransitionStyle = UIModalPresentationCustom; // incorrect

instead of

controller.modalPresentationStyle = UIModalPresentationCustom; // correct

thanks to apple developer's support )

[andreamazz]

Sneaky! Glad that this wasn't related to the lib itself.
Thanks for solving the mystery @slxl 👍

Cheers

[slxl]

i'd say, glad it wasn't related to Obj-C :)

[andreamazz]

That would have been awkward 😬

[alicanbatur]

This fixed for me, using
controller.modalPresentationStyle = UIModalPresentationCustom;
instead of
controller.modalTransitionStyle = UIModalPresentationCustom; // incorrect

fyi.
(I'm on a objc project btw.)
