我得到了一个带有NavigationController
的应用程序。如何更改pushViewController
和popToViewController
的动画转换样式?
UPD-
我创建了类似@lawicko答案的类别。但我在尝试调用函数时出错了
[self.navigationController pushViewController:places withCustomTransition:CustomViewAnimationTransitionPush子类型:CustomViewAnimationSubtypeFromLeft];
错误为:"使用未声明的标识符'CustomViewAnimationTransitionPush'"
我应该在哪里申报这个部分:
typedef enum {
CustomViewAnimationTransitionNone,
CustomViewAnimationTransitionFlipFromLeft,
CustomViewAnimationTransitionFlipFromRight,
CustomViewAnimationTransitionCurlUp,
CustomViewAnimationTransitionCurlDown,
CustomViewAnimationTransitionFadeIn,
CustomViewAnimationTransitionMoveIn,
CustomViewAnimationTransitionPush,
CustomViewAnimationTransitionReveal
} CustomViewAnimationTransition;
现在写,我在UINavigationController+Additions.h
中声明
UPD 2:又有一个新错误:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_CATransition", referenced from:
objc-class-ref in UINavigationController+Additions.o
"_kCATransition", referenced from:
并且相同的错误foor所有_kCATransitions
查看我创建的这个UINavigationController
类别。它允许你推送和弹出几乎所有可能的转换,还支持QuartzCore转换的子类型,这将允许你做你想做的事情——从左边推送视图。这样做:
[self.navigationController pushViewController:[[MyController alloc] init] withCustomTransition:CustomViewAnimationTransitionPush subtype:CustomViewAnimationSubtypeFromLeft];
代码如下。你需要放在标题部分的第一部分:
// 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在实现文件中:
#import "UINavigationController_Additions.h"
@interface UINavigationController()

您需要将QuartzCore.framework
添加到目标中以解决_OBJC_CLASS_$_CATransition
错误。
我最近处理了创建自己的转换的问题,下面是我制作的可重用库:
https://github.com/travisjeffery/TRVSNavigationControllerTransition
这是我的博客文章,谈论如何进行自己的转变。
不过,基本想法很简单,只需拍摄导航控制器(当前)视图的CALayer快照,然后在没有动画的情况下关闭视图,拍摄新视图的CALlayer快照,然后将自己的动画添加到这些层,然后在动画完成后删除这些层。
