迅速:

navigationController!.interactivePopGestureRecognizer!.enabled = false

我发现只把手势设置为禁用并不总是有效。它确实有用，但对我来说，只有在我用过一次后才起作用。第二次就不会触发手势了。

修复我是委托手势和实现shouldbegin方法返回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;
}

迅速:

navigationController!.interactivePopGestureRecognizer!.enabled = false

它适用于我的大多数视图控制器。

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

对于一些视图控制器，比如UIPageViewController，它并不是无效的。在UIPageViewController的pagecontentviewcontroller下面的代码为我工作。

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
}

从iOS 8开始，接受的答案不再有效。我需要在我的主游戏屏幕上停止滑动来解散手势，所以执行了这个:

- (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;
}

请在root vc下设置:

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

}

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