How to press "Back" button in UINavigationController programmatically

Question

I have a UIViewController called FriendsViewController inside a UINavigationController. And a second UIViewController called FriendsDetailedViewController. When navigating from the first view controller to the second, I want to programmatically press the Back button when needed. How to do this?

May be you just want to pop to previous view? – Nekto Oct 04 '11 at 09:50 — Nekto, Oct 04 '11 at 09:50

Simply use

[self.navigationController popViewControllerAnimated:YES]

from FriendsDetailedViewController. Your view will be popped out i.e. the behavior of back button.

Note that it returns UIViewController on normally, and returns nil if there is nothing to pop.

If by pressing "Back" button you mean just to go to the previous view controller, you can just call:

[self.navigationController popViewControllerAnimated:YES];

Here is the swift method

    navController.popViewControllerAnimated(true)
}

Or just `navigationController?.popViewControllerAnimated(true)`. – clozach Feb 11 '15 at 19:33

Swift 5

 self.navigationController?.popViewController(animated: true)

Usage in a code snippet:

func unwindViewController() {
    self.navigationController?.popViewController(animated: true)
}

Here is how I did it in Swift 3

_ = self.navigationController?.popViewController(animated: true)

_ is used to suppress the ugly warning generated by XCode.

You do not let, so you can just write: _ = self.navigationController?.popViewController(animated: true) – Brian Ogden Sep 18 '17 at 04:09
@BrianOgden Thanks for the tip :) – Jay Mayu Sep 19 '17 at 05:41

1) When you pop in current NavigationController Then

In Swift

self.navigationController?.popViewControllerAnimated(true)

Objective C

[self.navigationController popViewControllerAnimated:YES];

2) When you back another Navigation controller Then

In Swift

let story = UIStoryboard(name: "Main", bundle: nil)
let pushVC = story.instantiateViewControllerWithIdentifier("PushVC")
let navigation = story.instantiateViewControllerWithIdentifier("homeNavigation") as! UINavigationController
navigation.pushViewController(pushVC!, animated: true)

In Objective C

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"storyBoardName" bundle:nil];
pushVC* ObjectOfPushVC = [storyboard instantiateViewControllerWithIdentifier:@"pushVC"];

[self.navigationController pushViewController:ObjectOfPushVC animated:YES];
