更改animation转换
我有一个与NavigationController的应用程序。 我如何更改pushViewController和popToViewControlleranimation过渡样式？
UPD
我创build类似@lawicko的答案。 但是当我试图调用函数的时候出错了
[self.navigationController pushViewController：放置withCustomTransition：CustomViewAnimationTransitionPush子types：CustomViewAnimationSubtypeFromLeft];
错误是：“使用未声明的标识符'CustomViewAnimationTransitionPush'”
我应该在哪里申报这部分：
typedef enum { CustomViewAnimationTransitionNone, CustomViewAnimationTransitionFlipFromLeft, CustomViewAnimationTransitionFlipFromRight, CustomViewAnimationTransitionCurlUp, CustomViewAnimationTransitionCurlDown, CustomViewAnimationTransitionFadeIn, CustomViewAnimationTransitionMoveIn, CustomViewAnimationTransitionPush, CustomViewAnimationTransitionReveal } CustomViewAnimationTransition;
现在写我宣布它在UINavigationController+Additions.h
UPD 2：另外一个新的错误：
Undefined symbols for architecture i386: "_OBJC_CLASS_$_CATransition", referenced from: objc-class-ref in UINavigationController+Additions.o "_kCATransition", referenced from:
和所有的_kCATransitions相同的错误
看看我创build的这个UINavigationController类别。 它允许你在几乎所有可能的转换中推送和popup，还支持QuartzCore转换的子types，这将允许你做到你想要的 – 从左侧推视图。 像这样做：
[self.navigationController pushViewController:[[MyController alloc] init] withCustomTransition:CustomViewAnimationTransitionPush subtype:CustomViewAnimationSubtypeFromLeft];
代码如下。 第一部分你需要放在标题部分：
// IMPORTANT - basic transitions like flip and curl are local, they reside only in animation block. Core animations however, // once assigned to the layer, stay until changed or reset (by assigning nil as layer animation property) #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> #import <QuartzCore/QuartzCore.h> typedef enum { CustomViewAnimationTransitionNone, CustomViewAnimationTransitionFlipFromLeft, CustomViewAnimationTransitionFlipFromRight, CustomViewAnimationTransitionCurlUp, CustomViewAnimationTransitionCurlDown, CustomViewAnimationTransitionFadeIn, CustomViewAnimationTransitionMoveIn, CustomViewAnimationTransitionPush, CustomViewAnimationTransitionReveal } CustomViewAnimationTransition; #define CustomViewAnimationSubtypeFromRight kCATransitionFromRight #define CustomViewAnimationSubtypeFromLeft kCATransitionFromLeft #define CustomViewAnimationSubtypeFromTop kCATransitionFromTop #define CustomViewAnimationSubtypeFromBottom kCATransitionFromBottom @interface UINavigationController(Additions) - (void)pushViewController:(UIViewController *)viewController withCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype; - (void)popViewControllerWithCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype; - (void)popToRootViewControllerWithCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype; - (void)popToViewController:(UIViewController *)viewController withCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype; @end
第二部分你需要放在执行文件中：

您需要将QuartzCore.framework添加到您的目标来解决_OBJC_CLASS_$_CATransition错误。
我最近解决了创build自己的转换，这是我创build的可重用的库：
https://github.com/travisjeffery/TRVSNavigationControllerTransition
这里是我的博客文章，谈论如何使自己的过渡。
基本的想法非常简单，只需要导航控制器的（当前）视图的CALayer快照，然后推动/popup视图没有animation，采取CALayer快照的新视图，然后添加自己的animation到这些层，然后一旦animation完成，移除这些图层。
