I got the default iOS Master-Detail project (using Swift) from Xocde 6 beta 3.
Deployment target 7.1
There is a UISplitViewController which has an array of 2
UINavigationControllers, both have each one UIViewController: the first has
MasterViewController, the second one has DetailViewController.
UISplitViewController:
UINavigationController-1 → [MasterViewController]
UINavigationController-2 → [DetailViewController]
I added this to DetailViewController:
init( coder: NSCoder )
{
super.init(coder: coder)
println("\ninit \(self)") // seen whenever a
DetailView is appearing
}
And I see that when ever there is a segue from Master to Detail this happens:
a new DetailViewController is created and the second UINavigationController in
UISplitViewController changes and points to the just created
DetailViewController controller.
UISplitViewController:
UINavigationController-1 → [MasterViewController] //
unchanged
UINavigationController-2b → [DetailViewController-b] // both
changing at every segue
Is this expected behaviour?
Cannot be: in didFinishLaunchingWithOptions the UISplitViewController gets as
delegate the first ever DetailViewController, which subsequently is never used.
Also after using the Back button (top left of Detail View) once, there never
will be such a button to be used.
Probably result of current DetailViewController NOT being delegate of
UISplitViewController.
How to fix this (meaning: the segue should reuse the already existing stuff in
UISplitViewController instead creating new things) ?
Gerriet.
