uiswipegesturerecognizerdirectionup 和 uinavigationcontroller 不工作？

Question

我正在使用 uiswipegesturerecognizerdirectionup 和 down。它工作正常，但是当我添加 UINavigationController 时，滑动不起作用。 这是我的代码...

//In viewDidLoad

UISwipeGestureRecognizer *gesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipe:)];
gesture.direction = UISwipeGestureRecognizerDirectionUp | UISwipeGestureRecognizerDirectionDown;
[self.view addGestureRecognizer:gesture];

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onTapViewController:)];
[self.view addGestureRecognizer:tap];


-(void)didSwipe:(UIGestureRecognizer *)gestureRecognizer {

CATransition *animation = [CATransition animation];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromTop];
[animation setDuration:1.25];
[animation setDelegate:self];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
CALayer *layer = [self.view layer];
[layer addAnimation:animation forKey:nil];
[self.view.window addSubview:self.view];

}

- (void) onTapViewController: (UIGestureRecognizer *) gesture {
}

- (IBAction)onClickBtn:(id)sender {

GotoNextViewController *gnvc = [self.storyboard instantiateViewControllerWithIdentifier:@"GNVC"];
[self.navigationController pushViewController:gnvc animated:NO];

}

在这里，当我点击按钮导航时工作正常，但滑动不工作。

Answer 1

像这样将您的 GestureRecognizer 添加到您的 navigationController 视图中：

[self.navigationController.view addGestureRecognizer:gesture];
[self.navigationController.view addGestureRecognizer:tap];

Answer 2

    UISwipeGestureRecognizer *gesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipe:)];
    gesture.direction = UISwipeGestureRecognizerDirectionUp | UISwipeGestureRecognizerDirectionDown;
    [self.view addGestureRecognizer:gesture];



and animation

    -(void)didSwipe:(UIGestureRecognizer *)gestureRecognizer {

        CATransition *animation = [CATransition animation];
        [animation setType:kCATransitionPush];
        [animation setSubtype:kCATransitionFromTop];
        //    [animation setSubtype:kCATransitionFromBottom];
        [animation setDuration:1.25];
        [animation setDelegate:self];
        [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
        [self.view.layer addAnimation:animation forKey:nil];

    }
