I have a hard time understanding the segue unwinding.
I have a simple storyboard setup. UIViewController with
UINavigationController. On a table cell click a custom segue pushes a
new UIViewController onto the navigation stack. But then pressing the
"back" button in the navigation bar, it only uses the default pop
animation.
Now the is the question how do I tell the navigation controller to use
my custom segue when popping back? There are
segueForUnwindingToViewController:fromViewController:identifier:
canPerformUnwindSegueAction:fromViewController:withSender:
but it seems like those do not get called unless there is an action
- (IBAction)unwind:(UIStoryboardSegue *)segue;
wired up to the exit. Unfortunately IB doesn't allow me to wire that
up to the back button.
Any suggestions?
I've already wasted so much time on this that I am almost tempted to
go down the route of subclassing UINavigationController, trying to
trigger a segue manually on a pop.
cheers,
Torsten
