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?

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;
}
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)

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
}

迅速:

navigationController!.interactivePopGestureRecognizer!.enabled = false

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
    }

}
