如何在视图控制器之间进行淡入/无过渡

Question

是否可以在故事板中的视图控制器之间进行淡入和淡出过渡。或者没有过渡。

如果可以的话，代码是什么？

Answer 1

如果呈现模态视图控制器，您可以指定

modalTransitionStyle

或

UIModalTransitionStyleCrossDissolve

。如果在故事板中使用 Segue 执行此操作，请选择 Segue 的属性检查器，并在其中指定过渡样式：

enter image description here

如果以编程方式呈现视图控制器，您可以使用“交叉溶解”的“过渡”在故事板中的视图控制器之间定义模态转场，然后让源视图控制器执行此转场：

[self performSegueWithIdentifier:@"presentSegue" sender:sender];

或者，如果您打电话

presentViewController

：

UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"YourStoryboardID"];
controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:controller animated:YES completion:nil];

在 iOS 7 中，Apple 提供了一项新技术，可以为高度定制的过渡提供丰富而强大的控制。有关更多信息，请参阅 WWDC 2013 视频使用视图控制器自定义过渡。

但是，例如，如果您想在 iOS 7 中自定义推送和弹出动画以淡入淡出，则可以为导航控制器指定

delegate

- (void)viewDidLoad {
    [super viewDidLoad];

    self.navigationController.delegate = self;
}

然后您将实现

animationControllerForOperation

，指定用于推送和弹出的动画对象：

- (id<UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController
                                  animationControllerForOperation:(UINavigationControllerOperation)operation
                                               fromViewController:(UIViewController*)fromVC
                                                 toViewController:(UIViewController*)toVC
{
    if (operation == UINavigationControllerOperationPush)
        return [[PushAnimator alloc] init];

    if (operation == UINavigationControllerOperationPop)
        return [[PopAnimator alloc] init];

    return nil;
}

您显然必须实现自定义的推送和弹出动画师，例如：

@interface PushAnimator : NSObject <UIViewControllerAnimatedTransitioning>

@end

@implementation PushAnimator

- (NSTimeInterval)transitionDuration:(id <UIViewControllerContextTransitioning>)transitionContext
{
    return 0.5;
}

- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
{
    UIViewController* toViewController   = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];

    [[transitionContext containerView] addSubview:toViewController.view];

    toViewController.view.alpha = 0.0;

    [UIView animateWithDuration:[self transitionDuration:transitionContext] animations:^{
        toViewController.view.alpha = 1.0;
    } completion:^(BOOL finished) {
        [transitionContext completeTransition:![transitionContext transitionWasCancelled]];
    }];
}

@end

还有

@interface PopAnimator : NSObject <UIViewControllerAnimatedTransitioning>

@end

@implementation PopAnimator

- (NSTimeInterval)transitionDuration:(id <UIViewControllerContextTransitioning>)transitionContext
{
    return 0.5;
}

- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
{
    UIViewController* toViewController   = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
    UIViewController* fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];

    [[transitionContext containerView] insertSubview:toViewController.view belowSubview:fromViewController.view];

    [UIView animateWithDuration:[self transitionDuration:transitionContext] animations:^{
        fromViewController.view.alpha = 0.0;
    } completion:^(BOOL finished) {
        [transitionContext completeTransition:![transitionContext transitionWasCancelled]];
    }];
}

@end

还有一种类似但略有不同的技术用于自定义模式转换（尽管如果您只是做一张脸，您可能只会使用上面讨论的

modalTransitionStyle

，除非您想使用其他一些微妙的自定义）。有关更多信息，请参阅前面提到的使用视图控制器自定义转换。

底线，iOS 7 的自定义过渡是一种稍微复杂但非常强大的方法，可以对过渡动画提供巨大的控制。

Answer 2

为了创建自定义 Segue，请创建 UIStoryboard segue 的子类。例如：

// MCFadeSegue.h
#import <UIKit/UIKit.h>

@interface MCFadeSegue : UIStoryboardSegue

@end

// MCFadeSegue.m
#import <QuartzCore/QuartzCore.h>
#import "MCFadeSegue.h"

@implementation MCFadeSegue

- (void)perform
{
  CATransition *transition = [CATransition animation];
  transition.duration = 0.5;
  transition.type = kCATransitionFade;

  [[[[[self sourceViewController] view] window] layer] addAnimation:transition
      forKey:kCATransitionFade];

  [[self sourceViewController]
      presentViewController:[self destinationViewController]
      animated:NO completion:NULL];
}

@end

然后在MainStoryboard.storyboard中选择segue并设置Style:Custom和Class:MCFadeSegue。

Answer 3

Swift 中的推送/弹出 UIVIewController 淡入/淡出

class FadeInPushSegue: UIStoryboardSegue {

    var animated: Bool = true

    override func perform() {

        if var sourceViewController = self.sourceViewController as? UIViewController, var destinationViewController = self.destinationViewController as? UIViewController {

            var transition: CATransition = CATransition()

            transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
            sourceViewController.view.window?.layer.addAnimation(transition, forKey: "kCATransition")
            sourceViewController.navigationController?.pushViewController(destinationViewController, animated: false)


        }
    }

}

class FadeOutPopSegue: UIStoryboardSegue {

    override func perform() {

        if var sourceViewController = self.sourceViewController as? UIViewController, var destinationViewController = self.destinationViewController as? UIViewController {

            var transition: CATransition = CATransition()

            transition.duration = 0.4
            transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
            transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade

            sourceViewController.view.window?.layer.addAnimation(transition, forKey: "kCATransition")
            sourceViewController.navigationController?.popViewControllerAnimated(false)
        }
    }

}

Answer 4

试试这个。

    let transition: CATransition = CATransition()
    transition.duration = 0.4
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionFade
    self.navigationController!.view.layer.addAnimation(transition, forKey: nil)

    let vc = self.storyboard?.instantiateViewControllerWithIdentifier("vcID") as! My_ViewController
    self.navigationController?.pushViewController(vc, animated: false)

Answer 5

无需创建自定义 Segue，我就可以将这段代码放在一起来呈现视图...

UIViewController *nextView = [[UIStoryboardstoryboardWithName:@"Main"bundle:nil] instantiateViewControllerWithIdentifier:@"YOUR_VIEW_CONTROLLER_STORYBOARD_NAME"];

nextView.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

[self.navigationController PresentViewController:nextView 动画:YES 完成:nil];
//（对于交叉溶解，设置动画：YES。对于无过渡，设置动画：NO。）

希望这对遇到这个问题的人有所帮助！

Answer 6

我的 Swift 版本当然带有可选检查！

    let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
    if let stView = storyboard.instantiateViewControllerWithIdentifier("STVC") as? STVC {
        stView.modalTransitionStyle = UIModalTransitionStyle.CrossDissolve
        self.navigationController?.presentViewController(stView, animated: true, completion: nil)
    }

只需确保在IB中设置“视图控制器”的Storyboard ID即可

Answer 7

Swift 3语法中的Push/Pop UIVIewController FadeIn/FadeOut，基于Eugene Braginets的answer

class FadeInPushSegue: UIStoryboardSegue {

    var animated: Bool = true

    override func perform() {

        let sourceViewController = self.source
        let destinationViewController = self.destination

        let transition: CATransition = CATransition()

        transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
        sourceViewController.view.window?.layer.add(transition, forKey: "kCATransition")
        sourceViewController.navigationController?.pushViewController(destinationViewController, animated: false)

    }

}

class FadeOutPopSegue: UIStoryboardSegue {

    override func perform() {

        let sourceViewController = self.source

        let transition: CATransition = CATransition()

        transition.duration = 0.4
        transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = kCATransitionFade; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade

        sourceViewController.view.window?.layer.add(transition, forKey: "kCATransition")
        _ = sourceViewController.navigationController?.popViewController(animated: false)
    }

}

斯威夫特5：

花了几个小时寻找正确的解决方案后Rob的解决方案满足了我的所有需求，经过一些调整后它是完美的。

创建淡入淡出视图控制器类：

class FadeViewControllerTransition: NSObject, UIViewControllerAnimatedTransitioning {
    
    var fadeOut: Bool = false
    
    func transitionDuration(
        using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
        return 0.5
    }
    
    func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        
        if fadeOut {
            animateFadeOut(using: transitionContext)
            return
        }
        
        let toViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
        transitionContext.containerView.addSubview(toViewController.view)
        toViewController.view.alpha = 0.0
        UIView.animate(withDuration: transitionDuration(using: transitionContext), animations: {
            toViewController.view.alpha = 1.0
        }, completion: { _ in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
        })
    }
    
    func animateFadeOut(using transitionContext: UIViewControllerContextTransitioning) {
        
        let toViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.to)!
        let fromViewController = transitionContext.viewController(forKey: UITransitionContextViewControllerKey.from)!
        transitionContext.containerView.insertSubview(toViewController.view, belowSubview: fromViewController.view)
        UIView.animate(withDuration: transitionDuration(using: transitionContext), animations: {
            fromViewController.view.alpha = 0.0
        }, completion: { _ in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
        })
    }
}

在导航控制器的第一个视图控制器中：

class MainViewController: UIViewController, UIViewControllerTransitioningDelegate, UINavigationControllerDelegate {

    private let fadeVCTransition = FadeViewControllerTransition()
    
    func navigationController(_ navigationController: UINavigationController, animationControllerFor operation: UINavigationController.Operation, from fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        fadeVCTransition.fadeOut = (operation == .pop)
        return fadeVCTransition
    }

就是这样。

Answer 9

我所做的是在 Interface Builder 中使用 Storyboard，连接需要移动到/从和返回的两个视图控制器（按住 ctrl 并从原始视图控制器拖动单击到目标视图控制器），并更改 segue 属性。我使用了以下内容：

然后我使用了以下内容：

[self performSegueWithIdentifier:@"showMovieDetailSegue" sender:self];

当你想删除它时，只需从原始视图控制器中调用它：

[self dismissViewControllerAnimated:YES completion:nil];

简单且非常快速。

Answer 10

这让我彻底抓狂了好几个小时。这些解决方案似乎都不是我想要的，我快要失去理智了。最后提出了以下方案，它使用淡出/淡入过渡在单个 NSWindow 内交换视图控制器。首先它执行淡出，然后在完成处理程序中，它将窗口的视图设置为新视图并执行淡入。也许有更好的方法来做到这一点，但这是我可以一起破解的最简单方法.

class CustomSegue : NSStoryboardSegue {
    override func perform() {
        guard let fromController = sourceController as? NSViewController else {
            return;
        }
        guard let toController = destinationController as? NSViewController else {
            return;
        }
        let animationDuration = 0.5;
        NSAnimationContext.runAnimationGroup({
            $0.duration = animationDuration;
            fromController.view.animator().alphaValue = 0.0;
        }, completionHandler: {
            fromController.view.window?.contentViewController = toController;
            toController.view.alphaValue = 0.0;
            NSAnimationContext.runAnimationGroup({
                $0.duration = animationDuration;
                toController.view.animator().alphaValue = 1.0;
            })
        });

    }
}

Apple 文档中缺乏示例让我想破脑袋，而 Objective C 和 Swift 无处不在的混合只是......呸！

Answer 11

无需过渡即可呈现：

在故事板中选择你的segue
在属性检查器中取消选中“动画”

Answer 12

我想向

extension

提出一个

UINavigationController

，这是基于@Soumya Ranjan的回答：

extension UINavigationController {
    func addTransition(duration: CFTimeInterval = 0.25,
                       timingFunctionName: CAMediaTimingFunctionName = .easeInEaseOut,
                       type: CATransitionType = .fade,
                       forKey key: String? = nil) {
        let transition = CATransition()
        transition.duration = duration
        transition.timingFunction = CAMediaTimingFunction(name: timingFunctionName)
        transition.type = type
        view.layer.add(transition, forKey: key)
    }
}

用途： 在设置/推送新控制器进行导航之前，请务必致电

addTransition()

。

重要提示： 设置/推送

animated:

参数设置为

false

let viewController = UIViewController()

let navigationController = UINavigationController()
navigationController.addTransition() // <--- HERE
navigationController.setViewControllers([viewController], animated: false) // <--- HERE

也可以随意提供自定义参数：

navigationController.addTransition(
    duration: 0.4,
    timingFunctionName: .linear,
    type: .reveal,
    forKey: "CustomTransitionKey"
)
