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

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
}

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

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。

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。

它适用于我的大多数视图控制器。

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

override func viewDidLoad() {
   self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

}
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
}

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
    }

}
