如何完全重载视图？

Question

I know in IOS you can set a view to be redrawn with this:

self.view.setNeedsDisplay()

However, is there anyway to refresh the view in such a way that it recalls viewDidLoad() and all its constructor methods again?

Answer 1

What you can do is something like this:

var window: UIWindow?

let storyBoard : UIStoryboard = UIStoryboard(name: "StoryBoardName", bundle:nil)

let viewController = storyBoard.instantiateViewControllerWithIdentifier("ExampleIdentifier") as! ExampleViewController

And then inside whatever function:

window!.rootViewController = viewController
window!.makeKeyWindow()

This will basically reload/redraw the window. You should not try to directly call viewDidLoad()
