I am trying to force a navigation bar to show on a modal view. As per this answer, I am trying to do that by embedding just the modal view, nextScreenViewController in a special navigation controller, nextScreenNavigationController.
However, I am using delegate patterns to pass data between the initial viewController and nextScreenViewController. Before embedding in the navigationController, I was initalizing with the following code:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "goToNextScreen" {
let nextScreenDelegate = segue.destinationViewController as! nextScreenViewController
nextScreenDelegate.delegate = self
}
}
Some research suggested that, in order to account for nextScreenNavigationController I should use code like...
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "goToNextScreen" {
let navigation: UINavigationController = segue.destinationViewController as! nextScreenNavigationController
var nextScreenDelegate = nextScreenViewController.init()
nextScreenDelegate = navigation.viewControllers[0] as! nextScreenViewController
nextScreenDelegate.delegate = self
}
}
However, that fails without crashing - no data are passed.
Please comment if you want more of my delegate pattern... I just want to be sure it is not a basic implementation problem. Or, is there a better way to show a nav bar on a modal view?
