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

我找到了一个解决方案:

objective - c:

if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
    self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}

斯威夫特3 +: self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

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

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;
}

EDIT

如果您想管理特定导航控制器的滑动回滚功能,请考虑使用SwipeBack。

有了这个,你可以设置navigationController。swipeBackEnabled = NO。

例如:

#import <SwipeBack/SwipeBack.h>

- (void)viewWillAppear:(BOOL)animated
{
    navigationController.swipeBackEnabled = NO;
}

它可以通过CocoaPods安装。

pod 'SwipeBack', '~> 1.0'

我很抱歉没有解释清楚。

Swift 5、Swift 4.2可以使用下面的代码。

// disable
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
// enable
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true

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;
}
