iOs将动画从左向右（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，但它不在Interface Builder中呈现的四个故事板管理？ 具体来说，我想要一个类似于普通“封面垂直”的动画，但是要水平。我希望一个视图可以传递到另一个从左到右（或从右到左）的滑动，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，但没有财富：即使是从上到下过渡，无论如何，我不明白为什么默认转换是从上到下，当所有的应用程序的默认转换通常是正确的左或从左到右，尤其是在你刷卡的情况下...

我也尝试了以编程的方式，但没有财产，即使在这种情况下，使用此代码：

#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，我定义这作为我的继承课。使用断点，我看到它进入函数perfom，但...不执行！ 我以肖像模式封锁了应用程序（不知道它是否是问题）。我试图在真正的ipad和模拟iphone上运行应用程序。同样的问题。

您可以在自定义Segue中使用CATransition实现从左到右的过渡。此＃进口“QuartzCore/QuartzCore.h”添加到您的自定义Segue公司

-(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];  


}

我试过用塞格也做同样的效果，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"];

这里不使用导航控制器时是定制塞克运行的代码。

-(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]; 
}

基于扎基尔海德的提交，这里是相同的功能转换为斯威夫特：

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)  

}

试试下面这个例子在Github上：

https://github.com/itinance/iOSCustomSegue

它使用自定义SEGUE从右到左在一个示例应用程序中显式没有UINavigationController作为线程开启器的地方。

Sahil的回答中的代码在iOS 8中不适用于我。所以我不得不在这个问题上多调查一下。

'UIView animateWithDuration'适用于iOS 8，而'destinationController.view.layer addAnimation：transition'与presentViewController结合不起作用。
