How to create a segue to a Table View Controller Scene directly in a swift class file?

I am implementing FB Login. I have instantiated the FBSDKLoginButton() and added it to view directly from my ViewController.swift file (created and presented through the source code).

FBSDKLoginButton()

Normally I present a view modally by dragging and connecting the button to the new view in Interface Builder. However this button does not exist in my storyboard. How can I complete this task, but directly from my ViewController.swift file.

You can add manual segues from one ViewController to other ViewController.

ViewController

ViewController

In your FirstViewController in storyboard :

FirstViewController

storyboard

Connect the segue.

segue

Then select the connected segue and add Identifier:

segue

Identifier

Now you can use:

self.navigationController?.performSegue(withIdentifier: <The Identifier name>, sender: <If you want to send some data with it>)


you can use prepare(for segue: UIStoryboardSegue, sender: Any?):

prepare(for segue: UIStoryboardSegue, sender: Any?)

override func prepare(for segue: UIStoryboardSegue, sender: Any?)




to send data to the SecondViewCntroller.

SecondViewCntroller

Hope this helps.

Direct segue needs a connection from UI object to other view-controller. Rather segue, you can use pushViewController:

pushViewController

let sb = UIStoryboard(name: "Main", bundle: Bundle.main)
if let viewcontroller = sb.instantiateViewController(withIdentifier: "storyboardIdentifier") as? YourViewController
self.navigationController?.pushViewController(viewcontroller, animated: true)
