Description of Problem:
This class works if I don't assign .Delegate. It fails with SIGSEGV if I do
assign the Delegate.
class Container
{
public UINavigationController Nav { get; private set; }
UIViewController _vc;
Del _del;
public Container ()
{
_vc = new UITableViewController ();
Nav = new UINavigationController (_vc);
_del = new Del ();
Nav.Delegate = _del;
}
class Del : UINavigationControllerDelegate
{
public override void WillShowViewController (UINavigationController
navigationController, UIViewController viewController, bool animated)
{
Console.WriteLine ("SHOW: " + viewController);
}
}
}
