iOS: Go back to previous view

Question

I have two views like this in Story Board:

[View1] -> [Navigation Controller] -> [View2]

To go from View1(has tableview) to View 2, i do this on click of a row on View1:

self.performSegueWithIdentifier("showmyview2", sender:self)

This works.

Now i have a button on View 2, which when clicked should take me back to previous view i.e View 1.

I tried this:

 navigationController!.popViewControllerAnimated(true)

But this does not work. How do i go back to first view?

is your performsegue is pushview controller or presentview controller?? – Subcartilaginous

miuku> not sure, where do i see that? The NavigationController is UINavigationController class in identity inspector. Sorry i am new to iOS, Swift – Asparagus

your View1 is not in the navigationcontroller hierarchy, so you cannot call popViewController on navigationController to go back to View1 – Vuillard

Vinay> So how do i bring View1 in the navigationController hierarchy, or alternately any other solution? – Asparagus

@Asparagus you mean ViewController by View? – Tricornered

Answer 1

First Add a navigation controller to your First view1 through storyboard.(Editor->Embed Navigation controller), If navigation is not present.

OR

self.dismissViewControllerAnimated(true, completion: nil);

Call this function and try instead of navigation popviewcontroller

SWIFT 3.0 syntax has changed like this; self.dismiss(animated: true, completion: nil) – Underclothes

Answer 2

Use this code to present first view in your button action:

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("FirstView") as! TableViewController
self.presentViewController(vc, animated: true, completion: nil)

And don't forget to give Id to your First view.

Select your firstView into storyBoard and then click on Identity Inspector and you can assign StoryBoard ID like show into below Image.

self.dismiss(animated: true, completion: nil); this will work in swift 3
