iOS how to start a viewcontroller from framework - ios

Question

I have created my private framework successfully. It has no error. I have created a project now I want a simple thing but I do not have clue. Following is what I want
I want to start the Framework view controller.
You can think it is the whole app. I want to start its first view
controller. and then the app flow is as per business logic. I
want to exit app when user exit the Framework main view controller. Actually it was the complete app but I decided to make it framework for different clients because only small modifications are needed for different clients but I do not know how it should be done.
here is how I am trying to start first view controller in my Client project but it does not recognize that controller.
#IBAction func onClickBtnStartOver(_ sender: Any)
{
let storyBoard : UIStoryboard = UIStoryboard(name: "Storyboard", bundle:nil)
let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("idFrameworkVC") as FwViewController
self.presentViewController(nextViewController, animated:true, completion:nil)
}
It gives me error like "Use of undeclared type 'FwViewController'"
So what should I do to start the first viewcontroller of framework.
Note: I have viewcontrollers in one Storyboard namely Storyboard inside Framework

Answer 1

Declare an open func in your framework for opening first viewController :
open func presentFirstViewControllerOn(_ viewController:UIViewController) {
let storyBoard : UIStoryboard = UIStoryboard(name: "Storyboard", bundle:nil)
let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("idFrameworkVC") as FwViewController
viewController.presentViewController(nextViewController, animated:true, completion:nil)
}
and call this method from client app's VC.
Deciding which is the first VC (if needed) should be the responsibility of the framework, not your client app.

Answer 2

use your framework bundle identifier
let frameworkBundle = Bundle(identifier: "your framework bundle identifier")
let storyboard = UIStoryboard(name: "your framework storyboard name", bundle: frameworkBundle)
let mas = storyboard.instantiateInitialViewController() as! UIViewController
self.present(mas, animated: true, completion: nil)

Answer 3

Try this:
UIApplication.shared.keyWindow?.rootViewController = UIStoryboard(name: "yy", bundle: nil).instantiateInitialViewController()

Answer 4

If everything is setup nicely then you may have not imported your framework in it. This is very important part. Make double check if You have declared Public your framework VC.
Then After it you need to start It in you method.
