I have a class 'MyViewController.swift' and a string "MyViewController". How can I create an instance of that viewController from the string and push it in the navigation controller?
I've checked this answer (How to create an object depending on a String in Swift?) but it doesn't seem to do the trick.
Assuming you are working with storyboard, you could extend UIStoryboard like:
class func mainStoryboard() -> UIStoryboard {
return UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())
}
class func myViewController(s: String) -> UIViewController? {
return mainStoryboard().instantiateViewControllerWithIdentifier(s) as? UIViewController
}
and then you can use it like
myVC = UIStoryboard.myViewController("controller")
myVC.view.frame = view.frame
view.addSubview(myVC.view)
addChildViewController(myVC)
myVC.didMoveToParentViewController(self)
or
let vc = getVC("controller")
vc!.modalTransitionStyle = UIModalTransitionStyle.CrossDissolve
self.presentViewController(vc!, animated: true, completion: nil)
Update: If you are not using storyboards, you can add a something like this to your controller:
func getVC(s: String) -> UIViewController {
switch s {
case "myVc":
return MyVC() as! UIViewController
default:
// handle default case
}
}
