だから、私は 最初のビューにあるこのアプリhttp://itunes.apple.com/us/app/spg-mobile-app/id312306003?mt=8にあるアニメーションを実装しようとしています
ビューを反転するためのアニメーションを実装しましたが、片側をアニメーション化することに成功し、逆反転の逆ロジックを指定すると、ビュー間にギャップが生じます
ここに私のコードがあります
- (UIImage *)screenShot: (UIView *) aView
{
// Arbitrarily masks to 40%. Use whatever level you like
UIGraphicsBeginImageContext(hostView.frame.size);
[aView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
CGContextSetRGBFillColor (UIGraphicsGetCurrentContext(), 0, 0, 0, 0.4f);
CGContextFillRect (UIGraphicsGetCurrentContext(), hostView.frame);
UIGraphicsEndImageContext();
return image;
}
- (CALayer *) createLayerFromView: (UIView *) aView transform: (CATransform3D) transform
{
CALayer *imageLayer = [CALayer layer];
imageLayer.anchorPoint = CGPointMake(1.0f, 1.0f);
imageLayer.frame = (CGRect){.size = hostView.frame.size};
imageLayer.transform = transform;
UIImage *shot = [self screenShot:aView];
imageLayer.contents = (__bridge id) shot.CGImage;
return imageLayer;
}
- (void)animationDidStart:(CAAnimation *)animation
{
UIView *source = (UIView *) _source;
[source removeFromSuperview];
}
- (void)animationDidStop:(CAAnimation *)animation finished:(BOOL)finished
{
UITableView *dest = (UITableView *) destination;
dest.frame = CGRectMake(160, 0, 160, 460);
[hostView addSubview:dest];
[transformationLayer removeFromSuperlayer];
//if (delegate)
//SAFE_PERFORM_WITH_ARG(delegate, @selector(segueDidComplete), nil);
}
-(void)animateWithDuration: (CGFloat) aDuration
{
goesForward=FALSE ;
CAAnimationGroup *group = [CAAnimationGroup animation];
group.delegate = self;
group.duration = aDuration;
CGFloat halfWidth = hostView.frame.size.width; // 2.0f;
float multiplier = goesForward ? -1.0f : 1.0f;
CABasicAnimation *translationX = [CABasicAnimation animationWithKeyPath:@"sublayerTransform.translation.x"];
translationX.toValue = [NSNumber numberWithFloat:multiplier * halfWidth];
CABasicAnimation *translationZ = [CABasicAnimation animationWithKeyPath:@"sublayerTransform.translation.z"];
translationZ.toValue = [NSNumber numberWithFloat:-200.0]; //halfWidth];
CABasicAnimation *rotationY = [CABasicAnimation animationWithKeyPath:@"sublayerTransform.rotation.y"];
rotationY.toValue = [NSNumber numberWithFloat: multiplier * M_PI_2];
group.animations = [NSArray arrayWithObjects: rotationY, translationX, translationZ, nil];
group.fillMode = kCAFillModeForwards;
group.removedOnCompletion = NO;
[CATransaction flush];
[transformationLayer addAnimation:group forKey:kAnimationKey];
}
- (void) constructRotationLayer
{
UIView *source = (UIView *) _source;
UIView *dest = (UIView *) destination;
hostView = [source superview];
// if ([hostView isKindOfClass:[UIWindow class]]) {
// NSLog(@"I am window class");
// }
transformationLayer = [CALayer layer];
transformationLayer.frame = hostView.bounds; //CGRectMake(40, 0, 280, 460);
transformationLayer.anchorPoint = CGPointMake(0.5f, 0.5f);
CATransform3D sublayerTransform = CATransform3DIdentity;
sublayerTransform.m34 = 1.0 / -1000;
[transformationLayer setSublayerTransform:sublayerTransform];
[hostView.layer addSublayer:transformationLayer];
CATransform3D transform = CATransform3DMakeTranslation(0, 0, 0);
[transformationLayer addSublayer:[self createLayerFromView:source transform:CATransform3DRotate(transform, M_PI_2, 0, 0, 0)]];
transform = CATransform3DRotate(transform, M_PI_2, 0, 1, 0);
transform = CATransform3DTranslate(transform, hostView.frame.size.width, 0, 0);
if (!goesForward)
{
transform = CATransform3DRotate(transform, M_PI_2, 0, 1, 0);
transform = CATransform3DTranslate(transform, hostView.frame.size.width, 0, 0);
transform = CATransform3DRotate(transform, M_PI_2, 0, 1, 0);
transform = CATransform3DTranslate(transform, hostView.frame.size.width, 0, 0);
}
[transformationLayer addSublayer:[self createLayerFromView:dest transform:transform]];
}
- (void)perform
{
[self constructRotationLayer];
[self animateWithDuration:0.4f];
}
だから、ここで私は最初に実行メソッドを呼び出しています。ここに私の合計コードをアップロードしました
このコードは私にとっては少しうまくいきましたが、まだいくつかのギャップがあります。問題は、進行中のビューと次のビューのフレームが同じである必要があることです
