Disable Swipe Back Gesture in Swift

Disable swipe back gesture in Swift

You could disable it but that would not be to recommended as most iOS users go back by swiping and less by pressing the back button.
If you want to disable it it would be more reasonable to use a modal segue instead of a push segue which is not that big of a transfer.
If you really want to get rid of the swipe to go back function I would just disable the back button and have a done button on the top right of the screen.

self.navigationController?.navigationItem.backBarButtonItem?.isEnabled = false;

How to disable back/left swipe gesture?

From the controller you want this to be enabled/disabled just

Swift:

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false // or true

ObjC:

self.navigationController.interactivePopGestureRecognizer.enabled = NO; // or YES

How to disable back swipe gesture in UINavigationController on iOS 7

I found a solution:

Objective-C:

if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
    self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}

Swift 3+:
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

Disable swipe-back for a NavigationLink SwiftUI

By hiding the back-button in the navigation bar, the swipe-back gesture is disabled. You can set a custom back-button with .navigationBarItems()

struct ContentView: View {
    var body: some View {
        NavigationView{
            List{
                NavigationLink(destination: Text("You can swipe back")){
                    Text("Child 1")
                }
                NavigationLink(destination: ChildView()){
                    Text("Child 2")
                }
            }
        }
    }
}

struct ChildView: View{
    @Environment(\.presentationMode) var presentationMode

    var body:some View{
        Text("You cannot swipe back")
            .navigationBarBackButtonHidden(true)
            .navigationBarItems(leading: Button("Back"){self.presentationMode.wrappedValue.dismiss()})
    }
}

How to disable swipe back gesture with master-detail view in ios 11?

I figured it out. I had to add this to my DetailViewController

id savedGestureRecognizerDelegate1;
id savedGestureRecognizerDelegate2;

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        savedGestureRecognizerDelegate1 = self.navigationController.interactivePopGestureRecognizer.delegate;
        self.navigationController.interactivePopGestureRecognizer.delegate = self;
    }
    if ([self.navigationController.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        savedGestureRecognizerDelegate2 = self.navigationController.navigationController.interactivePopGestureRecognizer.delegate;
        self.navigationController.navigationController.interactivePopGestureRecognizer.delegate = self;
    }
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.delegate = savedGestureRecognizerDelegate1;
    }
    if ([self.navigationController.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.navigationController.interactivePopGestureRecognizer.delegate = savedGestureRecognizerDelegate2;
    }
}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer == self.navigationController.interactivePopGestureRecognizer || gestureRecognizer == self.navigationController.navigationController.interactivePopGestureRecognizer) {
        return NO;
    }
    return YES;
}

This is because there's two navigation controllers in a split view controller. The saved gesture recognizer delegate is because of this.

How to disable swipe back specifically on only one view controller

A better approach is to clear them from the stack when you show UserProfileVC

let profile  = self.storyboard?.instantiateViewController(withIdentifier: "profileID") as! UserProfileVC
self.navigationController?.viewControllers = [profile]

Edit: Do this inside profileVC

self.navigationController?.viewControllers = [self]

//

self.view.alpha = 0

UIView.animate(withDuration: 0.5) {

    self.view.alpha = 1

}

Overriding back swipe gesture in UINavigationController

You can do this in a combination of the following:

Add a swipe gesture recognizer to your view controller:

Add the following to your view controller class:

import UIKit

class SwipeBackViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        navigationController?.interactivePopGestureRecognizer?.isEnabled = false
    }

    @IBAction func swipeback(_ sender: UISwipeGestureRecognizer) {
        navigationController?.popToRootViewController(animated: true)
    }
}

• The command in viewDidLoad disables the default swipe recogninzer in iOS
• Then, the action associated with the swipe recognizer you added above handles the pop for you

My answer here goes into disabling the recognizer in more detail in case you have any questions on that.
