翻转,增长和翻译动画

Question

看看这个 MLB At Bat应用的视频.基本上,我只是想提出一个modalViewController与UIModalPresentationFormSheet风格,并从另一种观点认为成长,然后翻转.就像你在MLB应用程序的记分牌中点击一个游戏一样.谁知道我怎么能做到这一点？

谢谢

编辑:我的主视图与MLB应用程序几乎相同.我正在使用AQGridView并希望在点击网格视图中的单元格时发生动画.

编辑2:我也愿意放弃这个UIViewController概念,只使用一个简单的UIView,然后复制UIModalPresentationFormSheet手动的风格,如果这更容易.

编辑3:好的,忘记使用a UIViewController来做这个,因为我没有得到任何回复,我认为这是不可能的.我的新问题是如何使用UIView's' 在发布的视频中复制动画？所以基本上,初始视图需要同时增长,移动和翻转.

编辑4:我想我已经找到了实际的动画,现在我唯一的问题是计算要输入的坐标CATransform3DTranslate.我的观点需要与视频中的动画非常相似.它需要从另一个视图开始并动画到屏幕的中心.这是我如何计算中心弹出的视图的坐标:

CGPoint detailInitialPoint = [gridView convertPoint:view.frame.origin toView:detailView.frame.origin];
CGPoint detailFinalPoint = detailView.frame.origin;

gridView是我的主视图的容器视图,其中包含较小的网格项.view是我们动画的特定网格项.并且detailView是在屏幕中间出现的视图.

您可以使用UIViewControler上的类别实现自己的转换.

的UIViewController + ShowModalFromView.h

#import <Foundation/Foundation.h>
#import <QuartzCore/QuartzCore.h>

@interface UIViewController (ShowModalFromView)
- (void)presentModalViewController:(UIViewController *)modalViewController fromView:(UIView *)view;
@end

的UIViewController + ShowModalFromView.m

#import "UIViewController+ShowModalFromView.h"

@implementation UIViewController (ShowModalFromView)

- (void)presentModalViewController:(UIViewController *)modalViewController fromView:(UIView *)view {
    modalViewController.modalPresentationStyle = UIModalPresentationFormSheet;

// Add the modal viewController but don't animate it. We will handle the animation manually
[self presentModalViewController:modalViewController animated:NO];

// Remove the shadow. It causes weird artifacts while animating the view.
CGColorRef originalShadowColor = modalViewController.view.superview.layer.shadowColor;
modalViewController.view.superview.layer.shadowColor = [[UIColor clearColor] CGColor];

// Save the original size of the viewController's view    
CGRect originalFrame = modalViewController.view.superview.frame;

// Set the frame to the one of the view we want to animate from
modalViewController.view.superview.frame = view.frame;

// Begin animation
[UIView animateWithDuration:1.0f
                 animations:^{
                     // Set the original frame back
                     modalViewController.view.superview.frame = originalFrame;
                 }
                 completion:^(BOOL finished) {
                     // Set the original shadow color back after the animation has finished
                     modalViewController.view.superview.layer.shadowColor = originalShadowColor;
                 }];
}

@end

这很容易改变,以使用你想要的任何动画过渡; 对于你的,你可能想要使用CA3DTransform.希望这可以帮助!

好吧，我明白了。这就是我所做的：

CGFloat duration = 0.8;

/*
//Detail View Animations 
*/

CATransform3D initialDetailScale = CATransform3DMakeScale(view.frame.size.width/vc.view.frame.size.width, view.frame.size.height/vc.view.frame.size.height, 1.0);
CATransform3D initialDetailTransform = CATransform3DRotate(initialDetailScale, -M_PI, 0.0, -1.0, 0.0);
CATransform3D finalDetailScale = CATransform3DMakeScale(1.0, 1.0, 1.0);
CATransform3D finalDetailTransform = CATransform3DRotate(finalDetailScale, 0.0, 0.0, -1.0, 0.0);

NSMutableArray *detailAnimations = [NSMutableArray array];

CABasicAnimation *detailTransform = [CABasicAnimation animationWithKeyPath:@"transform"];
detailTransform.fromValue = [NSValue valueWithCATransform3D:initialDetailTransform];
detailTransform.toValue = [NSValue valueWithCATransform3D:finalDetailTransform];
detailTransform.duration = duration;
[detailAnimations addObject:detailTransform];

CABasicAnimation *detailFadeIn = [CABasicAnimation animationWithKeyPath:@"opacity"];
detailFadeIn.fromValue = [NSNumber numberWithFloat:1.0];
detailFadeIn.toValue = [NSNumber numberWithFloat:1.0];
detailFadeIn.duration = duration/2;
detailFadeIn.beginTime = duration/2;
[detailAnimations addObject:detailFadeIn];

CABasicAnimation *detailMove = [CABasicAnimation animationWithKeyPath:@"position"];
detailMove.fromValue = [NSValue valueWithCGPoint:vc.view.layer.position];
detailMove.toValue = [NSValue valueWithCGPoint:self.view.layer.position];
detailMove.duration = duration;
[detailAnimations addObject:detailMove];

CAAnimationGroup *detailGroup = [CAAnimationGroup animation];
[detailGroup setAnimations:detailAnimations];
[detailGroup setDuration:duration];
detailGroup.removedOnCompletion = NO;
detailGroup.fillMode = kCAFillModeForwards;
detailGroup.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
[vc.view.layer addAnimation:detailGroup forKey:@"anim"];

/*
//Grid Item View Animations
*/

CATransform3D initialGridScale = CATransform3DMakeScale(1.0, 1.0, 1.0);
CATransform3D initialGridTransform = CATransform3DRotate(initialGridScale, 0.0, 0.0, 1.0, 0.0);
CATransform3D finalGridScale = CATransform3DMakeScale(vc.view.frame.size.width/view.frame.size.width, vc.view.frame.size.height/view.frame.size.height, 1.0);
CATransform3D finalGridTransform = CATransform3DRotate(finalGridScale, M_PI, 0.0, 1.0, 0.0);

NSMutableArray *gridAnimations = [NSMutableArray array];

CABasicAnimation *gridTransform = [CABasicAnimation animationWithKeyPath:@"transform"];
gridTransform.fromValue = [NSValue valueWithCATransform3D:initialGridTransform];
gridTransform.toValue = [NSValue valueWithCATransform3D:finalGridTransform];
gridTransform.duration = duration;
[gridAnimations addObject:gridTransform];

CABasicAnimation *gridFadeOut = [CABasicAnimation animationWithKeyPath:@"opacity"];
gridFadeOut.fromValue = [NSNumber numberWithFloat:0.0];
gridFadeOut.toValue = [NSNumber numberWithFloat:0.0];
gridFadeOut.duration = duration/2;
gridFadeOut.beginTime = duration/2;
[gridAnimations addObject:gridFadeOut];

CABasicAnimation *gridMove = [CABasicAnimation animationWithKeyPath:@"position"];
gridMove.fromValue = [NSValue valueWithCGPoint:view.layer.position];
gridMove.toValue = [NSValue valueWithCGPoint:[self.view.layer convertPoint:self.view.layer.position toLayer:gridView.layer]];
gridMove.duration = duration;
[gridAnimations addObject:gridMove];

CAAnimationGroup *gridGroup = [CAAnimationGroup animation];
[gridGroup setAnimations:gridAnimations];
gridGroup.duration = duration;
gridGroup.fillMode = kCAFillModeForwards;
gridGroup.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
gridGroup.removedOnCompletion = NO;
[view.layer addAnimation:gridGroup forKey:@"anim"];

我正在使用AQGridView. 在我的代码示例中是我正在制作动画view的实例。AQGridViewCell这vc.view是我正在显示的详细UIViewController信息。UIView
