How to perform a segue by tapping a UIView

Question

I wonder if it is possible to conenct a UIView property to a UIViewController. By connecting a UIView, I want to transition to a second view controller. I have attempted several times by dragging and coding, but I just faild. I am looking for ways that do not need to program like using seague.

Is there anything that achievs this goal?

Thanks

Answer 1

Storyboard mode supports this (at least now.) Drag a Tap Gesture Recognizer onto your view you want to click. Then connect the gesture recognizer to the view you want to show, just like any other segue transition. Make sure any containing views are "User Interaction Enabled." No code required.

To perform a segue by tapping a UIView, you need to add a gesture recognizer. In my example I instantiate and added a Subclass of UIView programmatically :

viewDidLoad(){

    // here we instantiate an object of our subclass
    let customView = MyViewSubclass(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
    // here we add it to our ViewController
    self.view.addSubview(customView)

    // here we instantiate an object of gesture recognizer
    let gestureRec = UITapGestureRecognizer(target: self, action:  #selector (self.someAction (_:)))
    // here we add it to our custom view
    customView.addGestureRecognizer(gestureRec)
}

func someAction(sender:UITapGestureRecognizer){     
   performSegueWithIdentifier("Whazzzzup", sender: self)
}

// Swift 3
func someAction(_ sender:UITapGestureRecognizer){  

   // this is the function that lets us perform the segue   
   performSegue(withIdentifier: "Whazzzup", sender: self)
}

If you don't have a Subclass of UIView, then you just add a UIView...

let customView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))

Also you could of course just take your UIView Outlet and add the gesture recognizer to it.

let gestureRec = UITapGestureRecognizer(target: self, action:  #selector (self.someAction (_:)))
myView.addGestureRecognizer(gestureRec)

To present a ViewController without segue, you need to instantiate the ViewController:

func someAction(_ sender:UITapGestureRecognizer){
    let controller = storyboard?.instantiateViewController(withIdentifier: "someViewController")
    self.present(controller!, animated: true, completion: nil)
    // swift 2
    // self.presentViewController(controller, animated: true, completion: nil)
}

You need to set the withIdentifier in your ViewController's Attribute Inspector:

In this example withIdentifier would be: LandingVC

If you're using a UINavigationController and want a back Button, you push the ViewController on the Navigation stack:

self.navigationController?.pushViewController(controller!, animated: true)
