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?


当前回答

这是Swift 3的方式

对我有用

    self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

其他回答

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;
}

它适用于我的ios 10和更高版本:

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

}

它在viewDidLoad()方法上不起作用。

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

call

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

setViewControllers替换堆栈上的所有VCs,而不是在顶部添加一个新的控制器。这意味着新的集合VC是根VC,用户不能返回。

当你只想在一个VC上禁用滑动,而在另一个VC上保持滑动时,这是最有效的。

如果你想让用户能够返回,而不是通过滑动,不要使用这个方法,因为它会禁用所有返回(因为没有VC可以返回)

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];
