问题
This is regarding the latest version Xcode 6 and iOS 8.4.
I have a set of three view controllers, which VC2
& VC3
are presented modally:
VC1
-> VC2
-> VC3
Each of the segues are presented with a presentation style of .OverCurrentContext
. I am using this presentation style because both VC2
& VC3
have a UIVisualEffectView
with a blurred background to let the view underneath subtly show through.
My issue is that the unwind segue that I have created does not unwind neither VC2
or VC3
to VC1
with the presentation style of .OverCurrentContext
. However, when I change the presentation style back to .Defatult
it works.
I would really prefer to use .OverCurrentContext
because having to use dismissViewController:animated:completion
causes a second unwanted animation of both view controllers when dismissing. I want to be able to dismiss VC3
and immediately see VC1
without seeing VC2
animate it's dismissal between. Also, I do not like using presentingViewController.presentingViewController.dismissViewController:animated:completion
because it also causes the unwanted animation of dismissing VC2
after VC3
has been dismissed.
Any suggestions on how to solve this?
回答1:
I was able to use presentingViewController.presentingViewController.dismissViewController:animated:completion
from VC3
to achieve the same effect as using an unwind segue.
However, as noted in my comment, I would still like to know why I had to resort to this rather than being able to use an unwind segue with .OverCurrentContext
.
