Question

是否可以将pushViewController动画显示为presentModalViewController但背景功能为pushViewController？

Answer 1

如果你想要一个淡入淡出的动画，这种方法可行。

CATransition* transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:gridController animated:NO];

Answer 2

试试这个：

UIViewController *yourViewController = [[UIViewController alloc]init];

[UIView  beginAnimations: @"Showinfo"context: nil];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[self.navigationController pushViewController: yourViewController animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
[UIView commitAnimations];

Answer 3

用于显示PushViewConttroler动画，因为以下代码正在运行，

推送

 ViewController *VC = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
 CATransition* transition = [CATransition animation];
 transition.duration = 0.4f;
 transition.type = kCATransitionMoveIn;
 transition.subtype = kCATransitionFromTop;
 [self.navigationController.view.layer addAnimation:transition
                                                    forKey:kCATransition];
 [self.navigationController pushViewController:VC animated:NO];

POP

CATransition* transition = [CATransition animation];
transition.duration = 0.4f;
transition.type = kCATransitionReveal;
transition.subtype = kCATransitionFromBottom;
[self.navigationController.view.layer addAnimation:transition
                                            forKey:kCATransition];
[self.navigationController popViewControllerAnimated:NO];

但是有一个问题，它上/下时显示浅黑色背景，
继续努力，一旦完成，就在这里发布新代码。

Answer 4

适用于Xamarin（C＃）的所有等效代码来自上面的@hardik Thakkar的Answer，在动画过程中遇到黑色背景的问题，一切安好。

对于POP

    CATransition transition = CATransition.CreateAnimation();
    transition.Duration = 0.4;
    transition.Type = CAAnimation.TransitionReveal;
    transition.Subtype = CAAnimation.TransitionFromTop;
    this.NavigationController.View.Layer.AddAnimation(transition, nameof(CATransition));

对于推送

    CATransition transition = CATransition.CreateAnimation();
    transition.Duration = 0.4;
    transition.Type = CAAnimation.TransitionReveal;
    transition.Subtype = CAAnimation.TransitionFromBottom;
    this.NavigationController.View.Layer.AddAnimation(transition, nameof(CATransition));

Answer 5

您应该考虑做以下事情：

ViewController *myVC = [[ViewController alloc] initWithFrame:OFF_SCREEN];
[navigationController pushViewController:myVC animated:NO];

其中OFF_SCREEN是屏幕下方的一些CGRect，如（0,481,320,480）。然后使用动画块将viewcontroller的视图的frame.origin调整为（0,0）。您可能希望在viewDidLoad或viewDidAppear中执行animate块。

显示pushviewcontroller动画看起来像presentModalViewController
