how to instantiate/ show a TableViewController - ios

Question

I am struggling with this awful project for two weeks now and nothing seems to work. I have to do an app that loads some words from a server and presents them as pins on a map(MKView). I have to cluster the pins when the user zooms-out and for that I have used a this-party library written in Objective-C, but I also had to make a custom callout view with a button. When the user presses the said button the app should go to a TableViewController and here is my problem: I can't make it to do it. I have used before the "performSegueWIthIdentifier" and it worked very well, but now I get the error "there is no segue with '---' identifier". I know there are many other threads with this, but none of the solutions there work for me. Moreover, I have tried to instantiate the ViewController programmatically, but this does not work either because I get the "unexpectedly found nil..." and I don't know what to do any more.
I know I am doing something wrong, most probably how I call these functions, but I don't know what. This is what I have tried until now:
in the .xib file I have this:
import UIKit
class MarkerInfoView: MKAnnotationView {
#IBOutlet weak var theButton: UIButton!
#IBAction func readIt(sender: AnyObject) {
ViewController.goToArticles()
}
}
and in the ViewController:
class func goToArticles(){
ViewController().reallyGoToArticles()
}
I did this because I could not find another way to be able to call performSegueWithIdentifier or presentViewController
func reallyGoToArticles(){
println("let's go!")
let theArticlesSB = UIStoryboard(name: "Main", bundle: nil)
let vc = theArticlesSB.instantiateViewControllerWithIdentifier("theArticles") as! articlesViewController
self.presentViewController(vc, animated: true, completion: nil)
self.performSegueWithIdentifier("showArticles", sender: self)
}
I have uncommented both options just to show you.
I have uploaded the project here
Thank you very much!
Update
I forgot to mention that if I put the line
self.performSegueWithIdentifier("showArticles", sender: self)
in viewDidLoad it works

I had a look at your project and found your issue.
In MarkerInfoView.swift, you call ViewController.goToArticles() which is a class function:
class func goToArticles(){
ViewController().reallyGoToArticles()
}
This class function creates a NEW instance of ViewController which has nothing to do with the storyboard (and is not aware of segues).
You have to call self.reallyGoToArticles() from an instance method like
func goToArticles(){
self.reallyGoToArticles()
}
You have to manage to call the existing ViewController from your MarkerInfoView
EDIT: Here is how to achieve it
MarkerInfoView.swift
class MarkerInfoView: MKAnnotationView {
var vc: ViewController!
#IBOutlet weak var placePhoto: UIImageView!
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var detailsLabel: UILabel!
#IBOutlet weak var theButton: UIButton!
#IBAction func readIt(sender: AnyObject) {
vc.goToArticles()
}
}
ViewController.swift
func mapView(mapView: MKMapView!, didSelectAnnotationView annotation: MKAnnotationView!)
{
if let pin = annotation.annotation as? CustomPointAnnotation{
if var infoView = UIView.viewFromNibName("MarkerInfoView") as? MarkerInfoView {
infoView.nameLabel.text = pin.theTitle
infoView.detailsLabel.text = pin.theDetails
infoView.vc = self
infoView.center = CGPointMake(self.view.bounds.width/2, self.view.bounds.height/2)
self.view.addSubview(infoView)
} else {
}
}
}
func goToArticles(){
self.reallyGoToArticles()
}
