How to Disable the Swipe Back Gesture in iOS 8

Jul 9, 2015 at 15:37

iOS has a system gesture - swipe from the left edge of the screen and you go back to the previous screen. It's cool and intuitive, and it annoys me when apps disable it, but sometimes you still have to do it. For example, because of an interface decision that conflicts with this swipe.

So for iOS 8, add this to the current UIViewController:

in YouViewController.h:

// add the gesture handling protocol
@interface YouViewController : UIViewController <UIGestureRecognizerDelegate>

in YouViewController.m:

- (void)viewDidLoad {
  [super viewDidLoad];

  self.navigationController.interactivePopGestureRecognizer.enabled = NO;
  self.navigationController.interactivePopGestureRecognizer.delegate = self;
}

#pragma mark - UIGestureRecognizerDelegate

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
  // disable the gesture if this is swipe back
  if ([gestureRecognizer isEqual:self.navigationController.interactivePopGestureRecognizer]) {
    return NO;
  } else {
    return YES;
  }
}
