在iOS 7中,苹果增加了一个新的默认导航行为。你可以从屏幕的左边缘滑动回到导航堆栈。但在我的应用程序中,这种行为与我的自定义左侧菜单冲突。那么,是否有可能在UINavigationController中禁用这个新手势?

对于Swift 4,这是有效的:

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
    }

}

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;
}

只需从NavigationController中删除手势识别器。在iOS 8中工作。

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

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

这是Swift 3的方式

对我有用

    self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
