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

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

我的方法。一个手势识别器来统治它们:

class DisabledGestureViewController: UIViewController: UIGestureRecognizerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        navigationController!.interactivePopGestureRecognizer!.delegate = self
    }

    func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool {
        // Prevent going back to the previous view
        return !(navigationController!.topViewController is DisabledGestureViewController)
    }
}

重要:不要在导航堆栈的任何地方重置委托:navigationController!.interactivePopGestureRecognizer!.delegate = nil

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。

没有一个给出的答案帮助我解决这个问题。在这里张贴我的答案;可能对某人有帮助

声明私有var popGesture: UIGestureRecognizer?作为视图控制器中的全局变量。然后在viewDidAppear和viewWillDisappear方法中实现代码

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!)
    }
}

这将禁用滑动回iosv8。x起

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;
}
