将uiviewcontroller推送到另一个带有顶部 - 底部动画的viewcontroller

Question

在我的项目中有一个功能,当用户在顶部栏上滑动时,一个屏幕将出现从上到下的动画

有两个视图控制器oneviewcontroller.m

- (void)swipe
{
    listViewController *list_obj=[[listViewController alloc] initWithNibName:@"listViewController" bundle:NULL];
    UIViewAnimationTransition trans = UIViewAnimationTransitionCurlUp;
    [UIView beginAnimations: nil context: nil];
    [UIView setAnimationTransition: trans forView: [self.view window] cache: YES];
    [self.navigationController pushViewController:list_obj animated:YES];
    [UIView commitAnimations];
}

但是这并不能让动画从上到下

我想从Push实现导航:= top - bottom Pop:= bottom - top

请帮帮我谢谢

您可以将视图控制器从上到下推送,如下所示:

OBJ-C:

- (void) pushVC:(UIViewController )dstVC {
    CATransition transition = [CATransition animation];
    transition.duration = 0.5;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromTop;
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
    [self.navigationController pushViewController:dstVC animated:NO];
}

使用以下代码从下到上弹出视图控制器:

- (void) popVC {
    CATransition transition = [CATransition animation];
    transition.duration = 0.5;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionFade;
    transition.subtype = kCATransitionFromBottom;
    [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
    [self.navigationController popViewControllerAnimated:NO];
}

斯威夫特3:

  func open() {
    let settingsVC = SettingsVC()
    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionPush
    transition.subtype = kCATransitionFromTop
    navigationController?.view.layer.add(transition, forKey: kCATransition)
    navigationController?.pushViewController(settingsVC, animated: false)
  }

  func close() {
    let transition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionFade
    transition.subtype = kCATransitionFromBottom
    navigationController?.view.layer.add(transition, forKey:kCATransition)
    let _ = navigationController?.popViewController(animated: false)
  }
