How to disable back swipe gesture in UINavigationController on iOS 7

Question

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

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

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

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

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

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  - gt  Bool      if gestureRecognizer    self navigationController  interactivePopGestureRecognizer         return false         return true

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

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  lt SwipeBack SwipeBack h gt   -  void viewWillAppear  BOOL animated       navigationController swipeBackEnabled   NO      It can be installed via CocoaPods   pod  SwipeBack      gt  1 0    I appologize for lack of explanation

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

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  - gt  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

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
