更改动画过渡

Question

我收到了NavigationController的应用。如何更改pushViewController和popToViewController的动画过渡样式？

UPD

我在@lawicko回答中创建了类别。但是当我试图调用函数时我得到了错误

[self.navigationController pushViewController：places withCustomTransition：CustomViewAnimationTransitionPush subtype：CustomViewAnimationSubtypeFromLeft];

错误是：“使用未声明的标识符'CustomViewAnimationTransitionPush'”

我应该在哪里宣布这一部分：

typedef enum {
    CustomViewAnimationTransitionNone,
    CustomViewAnimationTransitionFlipFromLeft,
    CustomViewAnimationTransitionFlipFromRight,
    CustomViewAnimationTransitionCurlUp,
    CustomViewAnimationTransitionCurlDown,
    CustomViewAnimationTransitionFadeIn,
    CustomViewAnimationTransitionMoveIn,
    CustomViewAnimationTransitionPush,
    CustomViewAnimationTransitionReveal
} CustomViewAnimationTransition;

立即写信我在UINavigationController+Additions.h

中声明

UPD 2：还有一个新错误：

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_CATransition", referenced from:
      objc-class-ref in UINavigationController+Additions.o
  "_kCATransition", referenced from:

和所有_kCATransitions相同的错误

查看我创建的UINavigationController类别。它允许您推送和弹出几乎所有可能的过渡，并且还支持QuartzCore过渡的子类型，这将允许您完全按照您的需要进行操作 - 从左侧推送视图。这样做：

[self.navigationController pushViewController:[[MyController alloc] init] withCustomTransition:CustomViewAnimationTransitionPush subtype:CustomViewAnimationSubtypeFromLeft];

代码如下。您需要在标题部分放置的第一部分：

// 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

您需要将第二部分放入实施文件中：

#import "UINavigationController_Additions.h"

@interface UINavigationController()

- (void)standardAnimationWithController:(UIViewController*)viewController
                                duration:(NSTimeInterval)duration
                                options:(UIViewAnimationOptions)options
                                changesBlock:(void (^)(void))block;
- (void)coreAnimationWithController:(UIViewController*)viewController
                                duration:(NSTimeInterval)duration
                                type:(NSString*)type
                                subtype:(NSString*)subtype
                                changesBlock:(void (^)(void))block;
@end

您需要向目标添加QuartzCore.framework以解决_OBJC_CLASS_$_CATransition错误。

Answer 3

我最近处理了创建自己的转换，这是我制作的可重用库：

https://github.com/travisjeffery/TRVSNavigationControllerTransition

这是我的blog post谈论如何进行自己的过渡。

基本思路非常简单，只需获取navigationController（当前）视图的CALayer快照，然后在没有动画的情况下关闭/弹出视图，拍摄新视图的CALayer快照，然后将自己的动画添加到那些图层，然后在动画完成后删除这些图层。
