uiswipegesture_recognizerdirectionup und uinavigationcontroller funktionieren nicht?

Question

Ich arbeite mit uiswipegesture recognizer direction nach oben und unten. Es funktioniert ordnungsgemäß, aber wenn ich hinzufügen, UINavigationController Swipe funktioniert nicht. Dies ist mein Code ...

//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]; 

} 

hier, wenn i-Taste Navigation richtig funktioniert klicken, aber klauen nicht funktioniert.

Answer 1

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]; 

    }

Fügen Sie Ihre GestureRecognizer in Ihre navigationController Ansicht wie folgt aus:

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