ios - 显示 pushviewcontroller 动画看起来像 presentModalViewController

Question

是否可以显示pushViewController动画外观presentModalViewController但具有背景功能pushViewController？

Answer 1

如果你想淡化动画，这种方法有效。

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];

为了显示 PushViewController 动画，下面的代码正在工作，

 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];

对于流行音乐

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，它在上升/下降时显示浅黑色背景，正在处理
这个问题，一旦它在此处发布新代码。

Answer 4

对于所有在 Xamarin (C#) 中尝试的等效代码，来自上面@hardik Thakkar 的答案，在动画过程中有黑色背景的问题，一切都好。

流行音乐

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

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

您应该考虑执行以下操作：

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

其中 OFF_SCREEN 是屏幕下方的某个 CGRect，例如 (0, 481, 320, 480)。然后使用动画块将viewcontroller的view的frame.origin调整为(0, 0)。您可能希望在 viewDidLoad 或 viewDidAppear 中执行动画块。
