Ios 如何使用导航控制器关闭返回视图的自动手势？

因此，我注意到，当用户在屏幕的最左侧（任意方向）滑动时，我的所有视图都会收到返回（弹出视图）的手势（这是iOS7新增的功能）

到目前为止，我已尝试使用以下方法将其关闭，但没有任何效果：

    [self.navigationItem setHidesBackButton:YES];

在NavigationController本身的init中（代理似乎正在使用它）。

加布里埃尔的解决方案

要支持iOS 7之前的任何iOS，您需要使用以下代码包装此代码：

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

---

这将停止应用程序在iOS 6和iOS 5中因缺少选择器而崩溃。

将此代码用于iOS 7之前的版本

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

---

我发现将手势设置为“仅禁用”并不总是有效。它确实有用，但对我来说，它只是在我使用了一次后才起作用。第二次它不会触发回击动作

对我来说，解决方法是委派手势并实现shouldbeagin方法以返回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;
}

---

我在我的项目中使用此解决方案，它仅禁用InteractiveProgEstureRecognitor，并允许您使用其他手势识别器

- (void)viewDidLoad {

    [super viewDidLoad];

    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {

        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
        self.navigationController.interactivePopGestureRecognizer.delegate = self;

    }

}


- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {

    if ([gestureRecognizer isEqual:self.navigationController.interactivePopGestureRecognizer]) {

        return NO;

    } else {

        return YES;

    }

}

对于IOS 8（Swift）：

是 啊这很有效。但它仅在创建NavigationController后在AppDelegate中起作用。我试过初始化并加载导航控制器的实现，但没有成功。你说的初始化并加载导航控制器是什么意思？在我的导航控制器（UINavigationController的子类）中：我试过“-（id）initWithCoder:（NSCoder*）aDecoder{”添加：

super.navigationController.interactiveepogesturerecognizer.enabled=YES；self.navigationController.interactiveepogesturerecognizer.enabled=YES；

我将尝试实现

initWithNavigationBarClass:toolbarClass:

和

initWithRootViewController:

这两种由

UINavigation定义的初始化方法控制器

这不起作用，行：self.navigationController.interactiveepogesturerecognizer.delegate=self返回一个不符合协议的错误。我假设协议需要上述函数，但它不能解决错误。我将它放在viewDidLoad（）中在vc上我需要禁用它。没有一个答案适用于iOS8@sole007见下面我的答案..曾为me@PhilHudson显示一些代码。您是否将界面生成器中的NavigationController设置为自定义的？

- (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;
}

- (void)viewDidLoad {

    [super viewDidLoad];

    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {

        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
        self.navigationController.interactivePopGestureRecognizer.delegate = self;

    }

}


- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {

    if ([gestureRecognizer isEqual:self.navigationController.interactivePopGestureRecognizer]) {

        return NO;

    } else {

        return YES;

    }

}

class MainNavigationController: UINavigationController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.interactivePopGestureRecognizer.enabled = false

        // Do any additional setup after loading the view.
    }

}
