How to disable back swipe gesture in UINavigationController on iOS 7

In iOS 7 Apple added a new default navigation behavior. You can swipe from the left edge of the screen to go back on the navigation stack. But in my app, this behavior conflicts with my custom left menu. So, is it possible to disable this new gesture in UINavigationController?

I also found out that if you set navigationItem.hidesBackButton = true, this gesture also gets disabled. In my case i implemented a custom back button and add as a leftBarButtonItem

I found a solution:

Objective-C:

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

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


Of course, you need to check the availability of new methods if you are supporting old versions of the iOS.
Is there a way to disable it for a potion of the view?
You can enable / disable recognizer on viewDidAppear: / viewDidDisappear. Or, you can implement UIGestureRecognizerDelegate protocol with your more complex logic and set it as recognizer.delegate property.
On iOS8, setting self.navigationController.interactivePopGestureRecognizer.enabled property does not work in following view's methods: viewDidLoad, viewWillAppear, viewDidAppear, viewDidDisappear, but works in method viewWillDisappear. On iOS7 it works in all of above mentioned methods. So try to use it in any other methods while working on the viewController, I confirm it works for me on iOS8 when I click on some button inside of the view.
Can confirm that this will not work in iOS8 in viewDidLoad and viewWillAppear, putting it into viewwilllayoutgubviews did the trick

I found out setting the gesture to disabled only doesn't always work. It does work, but for me it only did after I once used the backgesture. Second time it wouldn't trigger the backgesture.

Fix for me was to delegate the gesture and implement the shouldbegin method to return NO:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    // Disable iOS 7 back gesture
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
        self.navigationController.interactivePopGestureRecognizer.delegate = self;
    }
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];

    // Enable iOS 7 back gesture
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
        self.navigationController.interactivePopGestureRecognizer.delegate = nil;
    }
}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    return NO;
}

Thanks! This is required to fully disable back swipe. It still exists in iOS 8, and smells like an Apple bug.
I dont know why but a view controller in my app for some unknown reason was crashing on this back gesture.. this saved me from finding it as I didnt needed this back gesture and so i disabled using this code.. +1
@AhsanEbrahim, when the back gesture starts, viewWillAppear is called on the view behind the current view. This can cause havoc in code logic since the current view is still active. Might be the cause of your crash.
Are the enabled yes/no lines needed? You return NO from gestureRecognizerShouldBegin, isn't that sufficient?
For anyone who was stuck on this like I was, if you are doing this for a master-detail view in a split view controller, you have to do the same for self.navigationController.navigationController. See stackoverflow.com/a/50012503/5605365

Just remove gesture recognizer from NavigationController. Work in iOS 8.

if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)])
    [self.navigationController.view removeGestureRecognizer:self.navigationController.interactivePopGestureRecognizer];

Also works in iOS 10, this should be the accepted answer. By the way, if you want to re-enable it, do [self.navigationController.view addGestureRecognizer:self.navigationController.interactivePopGestureRecognizer] somewhere.

As of iOS 8 the accepted answer no longer works. I needed to stop the swipping to dismiss gesture on my main game screen so implemented this:

- (void)viewDidAppear:(BOOL)animated
{
     [super viewDidAppear:animated];

if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
    self.navigationController.interactivePopGestureRecognizer.delegate = self;
    }
}

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

}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
     return NO;
}

While this works with iOS8 I get a warning on the line *.delegate = self; stating: Assigning to id' from incompatible type 'ViewController *const __strong'
As of iOS8, the accepted answer still works as expected. You are probably doing something else wrong..
Managed to get it semi working by calling the accepted answer in viewWillLayoutSubviews. However, swiping did cause the page to call 'viewDidLoad' again so reverted back to my answer above
@DavidDouglas: perhaps you could eliminate the warning with this code: __weak __typeof(self) theSafeSelf = self? Then set the delegate to theSafeSelf.
@DavidDouglas: You need to add to the interface to get rid of that warning

I've refined Twan's answer a bit, because:

your view controller may be set as a delegate to other gesture recognisers setting the delegate to nil leads to hanging issues when you go back to the root view controller and make a swipe gesture before navigating elsewhere.

The following example assumes iOS 7:

{
    id savedGestureRecognizerDelegate;
}

- (void)viewWillAppear:(BOOL)animated
{
    savedGestureRecognizerDelegate = self.navigationController.interactivePopGestureRecognizer.delegate;
    self.navigationController.interactivePopGestureRecognizer.delegate = self;
}

- (void)viewWillDisappear:(BOOL)animated
{
    self.navigationController.interactivePopGestureRecognizer.delegate = savedGestureRecognizerDelegate;
}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer == self.navigationController.interactivePopGestureRecognizer) {
        return NO;
    }
    // add whatever logic you would otherwise have
    return YES;
}

+1 "setting the delegate to nil leads to hanging issues when you go back to the root view controller and make a swipe gesture before navigating elsewhere."

Please set this in root vc:

-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:YES];
    self.navigationController.interactivePopGestureRecognizer.enabled = NO;

}

-(void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:YES];
    self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}

For Swift:

navigationController!.interactivePopGestureRecognizer!.enabled = false

This works, though I'd suggest using optional chaining instead of force unwrapping. e.g. self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

swift 5, swift 4.2 can use the code in the below.

// disable
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
// enable
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true

Logic

it works for me in ios 10 and later :

- (void)viewWillAppear:(BOOL)animated {
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
    }

}

it doesnt work on viewDidLoad() method.

EDIT

If you want to manage swipe back feature for specific navigation controllers, consider using SwipeBack.

With this, you can set navigationController.swipeBackEnabled = NO.

For example:

#import <SwipeBack/SwipeBack.h>

- (void)viewWillAppear:(BOOL)animated
{
    navigationController.swipeBackEnabled = NO;
}

It can be installed via CocoaPods.

pod 'SwipeBack', '~> 1.0'

I appologize for lack of explanation.


When promoting a project you're involved with you must disclose your affiliation with it.
Moreover, your project's only purpose is to manually enable the swipe gesture when the default system one isn't working, whereas the question asks how to disable that system wide gesture, so even if you set self.navigationController.swipeBackEnabled = NO I'm pretty sure this will only disable your library's swipe back gesture but the system's one will still be enabled.
Sorry for my short answer, I've just edited my answer with additional information: "useful for specific navigation controllers". Thanks!
It appears to use swizzle which is no longer allowed. iOS8?
@devxoul I am sorry! I thought I had read something a while ago saying that swizzling was no longer allowed. However, I cannot find anything that says this. Guess I am wrong.

My method. One gesture recognizer to rule them all:

class DisabledGestureViewController: UIViewController: UIGestureRecognizerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        navigationController!.interactivePopGestureRecognizer!.delegate = self
    }

    func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool {
        // Prevent going back to the previous view
        return !(navigationController!.topViewController is DisabledGestureViewController)
    }
}

Important: don't reset the delegate anywhere in the navigation stack: navigationController!.interactivePopGestureRecognizer!.delegate = nil

This is the way on Swift 3

works for me

    self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

All of these solutions manipulate Apple's gesture recognizer in a way they do not recommend. I've just been told by a friend that there's a better solution:

[navigationController.interactivePopGestureRecognizer requireGestureRecognizerToFail: myPanGestureRecognizer];

where myPanGestureRecognizer is the gesture recognizer you are using to e.g. show your menu. That way, Apple's gesture recognizer doesn't get turned back on by them when you push a new navigation controller and you don't need to rely on hacky delays that may fire too early if your phone is put to sleep or under heavy load.

Leaving this here because I know I'll not remember this the next time I need it, and then I'll have the solution to the issue here.

None of the given answers helped me to resolve the issue. Posting my answer here; may be helpful for someone

Declare private var popGesture: UIGestureRecognizer? as global variable in your viewcontroller. Then implement the code in viewDidAppear and viewWillDisappear methods

override func viewDidAppear(animated: Bool) {

    super.viewDidAppear(animated)

    if self.navigationController!.respondsToSelector(Selector("interactivePopGestureRecognizer")) {

        self.popGesture = navigationController!.interactivePopGestureRecognizer
        self.navigationController!.view.removeGestureRecognizer(navigationController!.interactivePopGestureRecognizer!)
    }
}


override func viewWillDisappear(animated: Bool) {

    super.viewWillDisappear(animated)

    if self.popGesture != nil {
        navigationController!.view.addGestureRecognizer(self.popGesture!)
    }
}

This will disable swipe back in iOS v8.x onwards


I am trying to imagine under what circumstances this would work, but Jack's would not. You say you tried all of the other answers: what went wrong when you tried Jack's?
On the other hand, this does seem simpler than Jack's, so maybe its not important. Decided I like this, because don't have to declare my class as a delegate, nor manipulate interactivePopGestureRecognizer.delegate.
BTW, code can be simplified. Remove if( .. respondsToSelector ... The next line sets popGesture to a recognizer, or to nil. Then use its value: if (self.popGesture != nil) self.navigationController .. removeGestureRecognizer( self.popGesture ).

This works in viewDidLoad: for iOS 8:

  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
      self.navigationController.interactivePopGestureRecognizer.enabled = false;
  });

Lots of the problems could be solved with help of the good ol' dispatch_after.

Though please note that this solution is potentially unsafe, please use your own reasoning.

Update

For iOS 8.1 delay time should be 0.5 seconds

On iOS 9.3 no delay needed anymore, it works just by placing this in your viewDidLoad:
(TBD if works on iOS 9.0-9.3)

navigationController?.interactivePopGestureRecognizer?.enabled = false

Unless you know when the gesture recognizer is installed on the view, waiting an arbitrary amount of time to disable it may or may not work.
@kalperin it's not guaranteed to work, though it's a very handy solution at some times. Use your own reasoning.
It working for me having version greater than iOS 8.1 :)
viewDidLoad plus delay is a risky programming practice. A bad habit to start. What if user starts the swipe before your delayed call kicks in? There is no safe time that is guaranteed to be long enough yet not too long. That is why other answers, posted long before yours, suggest placing the code in viewDidAppear. That ensures that everything is installed. Don't invent arbitrary delays; use Apple's sequence of calls as intended.
@iChirag true. I've noted that for 8.1 you need 0.5 second delay

It worked for me for most of the viewcontrollers.

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

It wasn't not working for some viewcontrollers like UIPageViewController. On UIPageViewController's pagecontentviewcontroller below code worked for me.

override func viewDidLoad() {
   self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
   self.navigationController?.interactivePopGestureRecognizer?.delegate = self
}
override func viewWillDisappear(_ animated: Bool) {
   self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
   self.navigationController?.interactivePopGestureRecognizer?.delegate = nil
}

On UIGestureRecognizerDelegate,

func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
   if gestureRecognizer == self.navigationController?.interactivePopGestureRecognizer {
      return false
}
      return true
}

For Swift 4 this works:

class MyViewController: UIViewController, UIGestureRecognizerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        self.navigationController?.interactivePopGestureRecognizer?.gesture.delegate = self
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(true)

        self.navigationController?.interactivePopGestureRecognizer?.gesture.isEnabled = false
    }

}

You should not override the interactive pop gesture delegate as it will cause undocumented behavior
I think it's not really overriding the delegate but just modifying the Boolean variable that they've provided for this very purpose, so it won't be a problem

self.navigationController.pushViewController(VC, animated: Bool)

call

self.navigationController.setViewContollers([VC], animated: Bool)

setViewControllers replaces all the VCs on the stack, instead of adding a new controller on top. This means that the new set VC is the root VC, and the user cannot go back.

This is most effective when you only want to disable the swipe on a single VC and keep the swipe-to-back for the other VC.

If you want users to be able to go back, just not through swiping, do not use this method as it will disable all backs (as there is no VC to go back to)
