Load UIViewController from the separate nib file in swift?
Solution 1
var viewController = OfferDetailViewController(nibName: "OfferDetailViewController", bundle: nil)
Solution 2
Here is a nice generic approach...
extension UIViewController {
class func loadFromNib<T: UIViewController>() -> T {
return T(nibName: String(describing: self), bundle: nil)
}
}
let vc : OfferDetailViewController = OfferDetailViewController.loadFromNib()
Solution 3
solution with type casting:
extension UIViewController {
static func initFromNib() -> Self {
func instanceFromNib<T: UIViewController>() -> T {
return T(nibName: String(describing: self), bundle: nil)
}
return instanceFromNib()
}
}
enjoyment:
let testVC = TestVC.initFromNib()
testVC.someCustomParam = "someValue"

I had take one ViewController with separate nib file. and my initial root viewcontroller is set in the storyBoard. Now the problem is that when I push to this controller the View hireachy methods are not being called (ViewDidLoad , ViewWillApper , etc)..
Code (View is loaded but methods are not calling)
var viewController = UIViewController(nibName: "OfferDetailViewController", bundle: nil) as OfferDetailViewController self.navigationController?.pushViewController(viewController, animated: true);
The same thing if i do with the storyboard its working fine.
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil) var viewController = mainStoryboard.instantiateViewControllerWithIdentifier("offer") as OfferDetailViewController self.navigationController?.pushViewController(viewController, animated: true);
Problem : With storyboard View hierarchy methods are calling but not with the separate nib file?
