Ios 手势识别器：shouldReceiveTouch:：发送到实例的无法识别的选择器

我知道未识别选择器问题的含义。这总是由于调用了未实现或未找到的方法。我已经实现了选择器，我也可以看到它

但我还是犯了这个错误。我正在使用控制

在用户注销并再次登录之前，它对我非常有用。登录后，当用户单击导航栏项时，我的应用程序崩溃，并显示：

[__NSCFType gestureRecognizer:shouldReceiveTouch:]: unrecognized selector sent to instance 0xc882da0

我正在我的

AppDelegate

中设置根控制器，如下所示：

    LeftMenuViewController *leftSideMenuController = [[LeftMenuViewController alloc] init];
    RightMenuViewController *rightSideMenuController = [[RightMenuViewController alloc] init];
    MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
                                                    containerWithCenterViewController:self.meNavigationController
                                                    leftMenuViewController:leftSideMenuController
                                                    rightMenuViewController:rightSideMenuController];
    [[self.meNavigationController.viewControllers lastObject] viewDidLoad];
    self.window.rootViewController = container;
    [self.window makeKeyAndVisible];

然后，在我的

viewController

中，我正在根据我的

viewDidLoad

方法中的此控件设置

navBarItems

我正在设置

navBarItems

：

#pragma mark - UIBarButtonItems

- (void)setupMenuBarButtonItems {
    self.navigationItem.rightBarButtonItem = [self rightMenuBarButtonItem];
    if(self.menuContainerViewController.menuState == MFSideMenuStateClosed &&
       ![[self.navigationController.viewControllers objectAtIndex:0] isEqual:self]) {
        self.navigationItem.leftBarButtonItem = [self backBarButtonItem];
    } else {
        self.navigationItem.leftBarButtonItem = [self leftMenuBarButtonItem];
    }
}

- (UIBarButtonItem *)leftMenuBarButtonItem {
    return [[UIBarButtonItem alloc]
            initWithImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"reveal-icon.png" ofType:nil]] style:UIBarButtonItemStyleBordered
            target:self
            action:@selector(leftSideMenuButtonPressed:)];
}

- (UIBarButtonItem *)rightMenuBarButtonItem {
    return [[UIBarButtonItem alloc]
            initWithImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"reveal-icon.png" ofType:nil]] style:UIBarButtonItemStyleBordered
            target:self
            action:@selector(rightSideMenuButtonPressed:)];
}

- (UIBarButtonItem *)backBarButtonItem {
    return [[UIBarButtonItem alloc] initWithTitle:BACK_BUTTON_NAVIGATION_BAR_BUTTON_STRING style:UIBarButtonItemStylePlain target:nil action:nil];
}

#pragma mark - UIBarButtonItem Callbacks

- (void)backButtonPressed:(id)sender {
    [self.navigationController popViewControllerAnimated:YES];
}

- (void)leftSideMenuButtonPressed:(id)sender {
    [self.menuContainerViewController toggleLeftSideMenuCompletion:^{
        [self setupMenuBarButtonItems];
    }];
}

- (void)rightSideMenuButtonPressed:(id)sender {
    [self.menuContainerViewController toggleRightSideMenuCompletion:^{
        [self setupMenuBarButtonItems];
    }];
}
