将uiviewcontroller从上到下推到另一个带有动画的viewcontroller

Question

在我的项目中，当用户在顶部栏上滑动时，一个屏幕将显示从上到下的动画

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];
}

但这并不能提供从上到下的动画

我想实现导航推：=顶部-底部Pop:=底部-顶部

请帮帮我感谢

您可以按如下方式从上到下推动视图控制器：

目标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查看控制器：

- (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];
}

Swift 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)
  }
