iOs Segue 动画从左到右（水平）

Question

我几乎是 Xcode 4 的新手。 有一种方法可以将自定义过渡动画添加到 segue 中，它不在故事板管理中 Interface Builder 提供的四个动画中？ 具体来说，我想要一个类似于正常的“垂直覆盖”但水平的动画。我希望一个视图从左到右（或从右到左）传递到另一个滑动，而不是从上到下，因为它发生在“覆盖垂直”过渡中。 我尝试了滑动手势但没有运气：即使是从上到下的转换，无论如何，我不明白为什么当所有应用程序的默认转换通常是从右到左或左时，默认转换是从上到下向右，尤其是在您滑动的情况下...

我也尝试了一种编程方式，但即使在这种情况下也没有运气，使用以下代码：

#import "JHCustomSegue.h"

@implementation JHCustomSegue
- (void) perform {
  UIViewController *src = (UIViewController *) self.sourceViewController;
  UIViewController *dst = (UIViewController *) self.destinationViewController;

  [UIView transitionWithView:src.navigationController.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{
        [src presentModalViewController:dst animated:NO];
    }
    completion:NULL];
}

@end

在界面生成器中，我将此类定义为我的 segue 类。使用断点，我看到它进入了函数 perfom 但是......不要执行！ 我已经以纵向模式阻止了该应用程序（不知道是否有问题）。我试图在真实的 ipad 和模拟的 iphone 上运行该应用程序。同样的问题。

Answer 1

在 Github 上查看这个示例：

https://github.com/itinance/iOSCustomSegue

它在示例应用程序中明确使用从右到左的自定义 segue，而没有 UINavigationController 作为请求的线程开启器。

Sahil 答案中的代码在 iOS 8 中对我不起作用。所以我不得不对这个问题进行更多调查。

'UIView animateWithDuration' 在 iOS 8 上工作，而 'destinationController.view.layer addAnimation:transition' 与 presentViewController 结合不做任何事情。

根据 Zakir Hyder 的提交，这里是翻译成 Swift 的相同功能：

override func perform() {

    var sourceViewController = self.sourceViewController as UIViewController
    var destinationViewController = self.destinationViewController as UIViewController

    var transition: CATransition = CATransition()

    transition.duration = 0.25
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionPush; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
    transition.subtype = kCATransitionFromLeft; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom

    sourceViewController.navigationController?.view.layer.addAnimation(transition, forKey: "kCATransition")
    sourceViewController.navigationController?.pushViewController(destinationViewController, animated: false)     

}

这是不使用导航控制器时自定义序列的工作代码。

-(void)perform
{

UIViewController *sourceViewController = (UIViewController*)[self sourceViewController];
UIViewController *destinationController = (UIViewController*)[self destinationViewController];

CATransition* transition = [CATransition animation];
transition.duration = 0.25;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionMoveIn; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
transition.subtype = kCATransitionFromRight; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom

[destinationController.view.layer addAnimation:transition forKey:kCATransition];
[sourceViewController presentViewController:destinationController animated:NO completion:nil];
}

Answer 4

您可以在自定义 Segue 中使用 CATransition 来实现从左到右的过渡。将此 #import "QuartzCore/QuartzCore.h" 添加到您的自定义 Segue

-(void)perform {

__block UIViewController *sourceViewController = (UIViewController*)[self sourceViewController];
__block UIViewController *destinationController = (UIViewController*)[self destinationViewController];                    

CATransition* transition = [CATransition animation];
transition.duration = .25;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
transition.subtype = kCATransitionFromLeft; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom



[sourceViewController.navigationController.view.layer addAnimation:transition
                                            forKey:kCATransition];

[sourceViewController.navigationController pushViewController:destinationController animated:NO];    


}

Answer 5

我也尝试使用 Segue 来实现相同的效果，但没有成功。相反，我使用了一种解决方法：

// get the view that's currently showing
UIView *currentView = self.view;
// get the the underlying UIWindow, or the view containing the current view
UIView *theWindow = [currentView superview];

UIView *newView = aTwoViewController.view; 

// remove the current view and replace with myView1
[currentView removeFromSuperview];
[theWindow addSubview:newView];

// set up an animation for the transition between the views
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

[[theWindow layer] addAnimation:animation forKey:@"SwitchToView2"];
