HYBControllerTransitions iOS自定义转场动画库 项目简介
HYBControllerTransitions是自定义围场动画API封装类库,使用简便。使用者不需要了解太多转场动画知识,即可轻松接入项目使用。这是一个给开发者们提供自定义push、pop、dismiss和present转场动画的开源组件。现在库中支持泡泡放大缩小围场、模态半屏转场和移动切换转场(KeyNote某转场效果)。对于开发者们来说,这是一个很不错的开源库。开发者不需要了解转场知识,只需要简单一个API就可以实现对应的功能。如果想要更深入地学习,请在源码中查看对应的注释说明!开源目标在设计此类库时,希望以最简洁的API来实现转场功能。如果不懂任何转场知识的人,也能轻松使用,那才算达到目标。因此,如果您没有学习过相关转场方面的知识,请不要担心,这个类库不需要您掌握太多转场的知识,只需要懂基本的OC语法即可轻松接入项目使用。公共的属性及API都封装在HYBBaseTransition类型中,它遵守了需要实现转场的所有协议并实现之。如果目前类库中所提供的效果不满足您的需求,您可以直接继承于HYBBaseTransition于实现您希望得到的效果。版本变化Version 1.0.1完善文档及去掉部分demo无关代码Version 1.1.0解决push/pop模式下,在push后,进入后台再进入前台时,会出现异常。原因是导航的代理交给了转场对象后,一直持有,因此才出现此问题。现在在poped的时候,会自动清除掉导航代理。如果在使用转场之前,已经有其它对象持有导航代理,应该在poped之后,交代理交还给原来的代理对象!支持弹簧动画效果默认转场动画使用的不是弹簧动画效果,如果觉得弹簧动画效果更佳,仅需要设置为YES即可。/**
* Default is NO, if set to YES, it will be presented and dismissed with
* spring animation.
*/
@property (nonatomic, assign) BOOL animatedWithSpring;当然,使用到弹簧自然需要设置其参数。不过作者都提供有默认值,都是经过调试过得到的值。如果觉得默认值所得到的效果不够好,请自行调整参数:/**
* The initial Spring velocity, Only when animatedWithSpring is YES, it will take effect.
* Default is 1.0 / 0.5. If you don't know, just use the default value.
*/
@property (nonatomic, assign) CGFloat initialSpringVelocity;
/**
* The Spring damp, Only when animatedWithSpring is YES, it will take effect.
*
* Default is 0.5. If you don't know, just use the default value.
*/
@property (nonatomic, assign) CGFloat damp;转场类型动画目前所支持的动画效果有以下:Bubble Effect Transition:泡泡放大、缩小的动画效果,仅支持模态呈现present/dismiss。Modal Effect Transition:半屏呈现转场,支持设置缩放系数、呈现高度等,仅支持模态呈现present/dismiss。Move Push/Pop Transition:移动切换转场效果,仅支持push/pop模式。Buble Effect Transitionpresent时,以泡泡圆形放大;dismiss时,以泡泡圆形缩小至起点。当需要实现此转场效果时,请使用HYBBubbleTransition类型。效果图如下:如何使用使用起来非常简单,只需要一个API且只在一处调用即可。比如,现在有HYBModalBubbleViewController,它有一个点击事件,在点击后会回调onPresent函数,然后配置如下即可实现转场:- (void)onPresent {
HYBBubbleFromBottomController *vc = [[HYBBubbleFromBottomController alloc] init];
vc.modalPresentationStyle = UIModalPresentationCustom;
// Remember to own it strongly
// Because delegate is weak reference, and it will be released after out of the function body.
self.bubbleTransition = [[HYBBubbleTransition alloc] initWithPresented:^(UIViewController *presented, UIViewController *presenting, UIViewController *source, HYBBaseTransition *transition) {
// You need to cast type to the real subclass type.
HYBBubbleTransition *bubble = (HYBBubbleTransition *)transition;
// If you want to use Spring animation, set to YES.
// Default is NO.
// bubble.animatedWithSpring = YES;
bubble.bubbleColor = presented.view.backgroundColor;
// 由于一个控制器有导航,一个没有,导致会有64的误差,所以要记得处理这种情况
CGPoint center = [self.view viewWithTag:1010].center;
center.y += 64;
bubble.bubbleStartPoint = center;
} dismissed:^(UIViewController *dismissed, HYBBaseTransition *transition) {
// Do nothing and it is ok here.
// If you really want to do something, here you can set the mode.
// But inside the super class, it is set to be automally.
// So you do this has no meaning.
transition.transitionMode = kHYBTransitionDismiss;
}];
vc.transitioningDelegate = self.bubbleTransition;
[self presentViewController:vc animated:YES completion:NULL];
}这里会present HYBBubbleFromBottomController这个控制器类,但是HYBBubbleFromBottomController对象什么也不需要做,就可以直接实现了转场。是不是真的很简单呢?如果想要了解更多功能功能,请在源代码中查看类中所提供的所有公开属性,几乎都有默认值,若不需要修改,直接使用默认值就可以了。注意事项:一定要将代理设置为对应的转场类对象。而且一定要在当前控制器强引用该转场类对象,因为设置为转场代理,只是弱使用,如果没有强引用,它就会被释放掉:// 代理不再是设置为self,而是设置为转场对象
vc.transitioningDelegate = self.bubbleTransition;Modal Effect Transition当需要实现半屏呈现且带缩放效果的转场动画时,可以使用此HYBModalTransition类。它仅支持present/dismiss模式。它提供了更多的属性设置,稍候讲解。效果如下:如何使用使用非常简单。假设在HYBModalHalfController有一个点击事件,点击后会回调onPresent函数,只需要在此函数中实现即可:- (void)onPresent {
HYBModalHalfDetailController *vc = [[HYBModalHalfDetailController alloc] init];
self.transition = [[HYBModalTransition alloc] initWithPresented:^(UIViewController *presented, UIViewController *presenting, UIViewController *source, HYBBaseTransition *transition) {
HYBModalTransition *modal = (HYBModalTransition *)transition;
modal.scale = (CGPoint){0.95, 0.95};
// If you don't specify, it will use default value
// modal.presentedHeight = 350.0;
// If you don't want to, set to YES or do no set.
modal.shouldDismissOnTap = YES;
// Default is NO, if set to YES, it will use spring animation.
modal.animatedWithSpring = YES;
// Default is YES. including navigation bar when take snapshots.
// When has navigation bar, if set to NO, it looks not so good.
// modal.scapshotIncludingNavigationBar = NO;
} dismissed:^(UIViewController *dismissed, HYBBaseTransition *transition) {
// do nothing
// 注释掉也没有关系,内部已经自动设置了。
transition.transitionMode = kHYBTransitionDismiss;
}];
vc.transitioningDelegate = self.transition;
[self presentViewController:vc animated:YES completion:NULL];
}对于HYBModalHalfDetailController控制器类,什么也不需要操作。这是不是有点太过于简单了?对于dismissed这个block,其实这里完全可以设置为nil,因为不需要做任何操作,默认就自动设置了mode。支持带导航截图如果当前控制器类有导航,最好还是连导航条也一起生成截图,这样效果会好很多。默认就是YES。如果不希望如此,请手动设置为N:/**
* Whether to include navigation bar when take snapshots.
* Default is YES. If NO, it has only the presenting view.
*/
@property (nonatomic, assign) BOOL scapshotIncludingNavigationBar;支持手势点击自动Dismiss在弹出来之后,默认是添加了点击手势,可以自动dismiss。默认为YES,如果不希望如此,请手动设置为NO:/**
* When tap on the presenting view, should it automatically is dismissed.
*
* Default is YES.
*/
@property (nonatomic, assign) BOOL shouldDismissOnTap;支持设置缩放、高度都提供了默认值,但是如果想要调整到一个让您满意的效果,也许这些属性就可以帮助您实现:/**
* Make the from view scale to the specified scale.
*
* Default is (0.9, 0.9)
*/
@property (nonatomic, assign) CGPoint scale;
/**
* The height for destination view to present.
*
* Default is half of destination view, it means desView.frame.size.height / 2
*/
@property (nonatomic, assign) CGFloat presentedHeight;Move Push/Pop Transition类似于KeyNote的神奇移动效果push、pop动画。效果图如下:使用起来也是很简单的,不同于present/dismiss模式,由于push的时候还不能得到转场过去的目标视图,比如效果图中的切换过去后看到的图片控件。在创建控制器类的时候,控件是不存在的,因此只能使用其它的办法来实现。这里所采用的方案是通过给UIViewController添加扩展属性,如此就可以在创建UI的地方,将目标控件赋值。扩展所添加的属性为:/**
* Set a target view to show. When push, it will transition to
* the target view. and when poped, it will pop from the target view.
*/
@property (nonatomic, strong, nonnull) UIView *hyb_toTargetView;如何使用假设当前控制器类为HYBMoveViewController,它有一个collectionview,呈风格布局显示一个图片列表。当点击cell的时候,就切换(push)到HYBMoveDetailController控制器中显示更多内容。实现如下:- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
HYBMoveDetailController *vc = [[HYBMoveDetailController alloc] init];
HYBGridModel *model = self.datasource[indexPath.item];
vc.image = model.clipedImage;
self.transition = [[HYBMoveTransition alloc] initWithPushed:^(UIViewController *fromVC, UIViewController *toVC, HYBBaseTransition *transition) {
HYBMoveTransition *move = (HYBMoveTransition *)transition;
HYBGridCell *cell = (HYBGridCell *)[collectionView cellForItemAtIndexPath:indexPath];
move.targetClickedView = cell.imageView;
move.animatedWithSpring = YES;
} poped:^(UIViewController *fromVC, UIViewController *toVC, HYBBaseTransition *transition) {
// Do nothing, unless you really need to.
}];
self.navigationController.delegate = self.transition;
[self.navigationController pushViewController:vc animated:YES];
}在点击的时候,需要创建一个转场对象,然后我们将导航类的代理设置为这个转场对象,如下:self.navigationController.delegate = self.transition;这样就可以实现内部自动处理了。当push的时候,会回调pushed闭包,在这里返回了转场对象,需要提供相关属性设置,才能实现。一定要传targetClickedView属性,这是被点击的控件,也是用于切换效果用的。注意:如果导航的代理原来是其它类对象持有,在poded闭包中应该要设置成原来的导航代理。在HYBMoveDetailController控制器中,在viewDidLoad这里创建UI的地方,创建了一个图片控件,然后如些设置:// You must specify a target view with this.
self.hyb_toTargetView = imgView;OK,到此就实现好功能了!是否足够简单?如何安装支持pod,可直接使用pod添加以下代码到Podfile中:pod 'HYBControllerTransitions', '~> 1.0.0'如果您的工程不支持Pod,呆直接将HYBControllerTransitions目录放到您的工程中即可!源代码如果不想使用pod来安装,或者想要看看demo,请到此处下载:HYBControllerTransitions致谢非常感谢andreamazz,学习了很多他的开源作品!
