Ios pushViewController的自定义动画

的动画创建自定义动画
我已经这样做了,currentViewController
上覆盖了我想要的图像,但我不知道在尝试反转动画图像的顺序时是否可以显示nextViewController
到目前为止,我有以下几点
- (IBAction)nextAction:(id)sender {
UIImage* img1 = [UIImage imageNamed:@"image-1.png"];
UIImage* img2 = [UIImage imageNamed:@"image-2.png"];
UIImage* img3 = [UIImage imageNamed:@"image-3.png"];
UIImage* img4 = [UIImage imageNamed:@"image-4.png"];
UIImage* img5 = [UIImage imageNamed:@"image-5.png"];
NSArray *animationImages = [NSArray arrayWithObjects:img1,img2,img3,img4,img5,nil];
CALayer *myLayer = [CALayer layer];
myLayer.bounds = CGRectMake(0.0, 0.0, 320.0, 480.0);
myLayer.position = self.view.center; //CGPointMake(0.0 ,0.0);
CAKeyframeAnimation *animationSequence = [CAKeyframeAnimation animationWithKeyPath: @"contents"];
animationSequence.calculationMode = kCAAnimationLinear;
animationSequence.autoreverses = NO;
animationSequence.duration = 0.4;
animationSequence.delegate = self;
animationSequence.repeatCount = 1; //HUGE_VALF;
NSMutableArray *animationSequenceArray = [[NSMutableArray alloc] init];
for (UIImage *image in animationImages)
{
[animationSequenceArray addObject:(id)image.CGImage];
}
animationSequence.values = animationSequenceArray;
[myLayer addAnimation:animationSequence forKey:@"contents"];
[self.view.layer addSublayer:myLayer];
}
- (void)animationDidStop:(CAAnimation*)animation finished:(BOOL)finished {
NextViewController *nextViewController;
nextViewController = [[NextViewController alloc] initWithNibName:@"NextViewController" bundle:nil];
nextViewController.title = @"next";
[self.navigationController pushViewController:nextViewController animated:NO];
[nextViewController release];
}
当用户按下按钮并且图像在当前视图顶部设置动画时,将执行iAction
nextAction
我想要实现的是在图像位于顶部后,将nextViewController
推到图像下方,并反转动画,以便显示nextViewController
我希望这是有道理的。这就像拥有一张照片,在照片的顶部放置一些卡片,然后移除显示不同照片的卡片
Teo不要将动画层添加到当前的viewController,而是直接将该层添加到当前的keyWindow。这将隐藏当前的viewController
[[[UIApplication sharedApplication] keyWindow] layer addSublayer:myLayer];
动画的前半部分完成后(或者换句话说,完成正向顺序的完整动画后),删除动画层。用新的viewController替换viewController,并将第二个动画层再次添加到keyWindow上-现在开始动画的后半部分。完成后,将动画层从关键帧窗口中移除
根据应用程序的结构,还可以使用有效位于其他ViewController下方的rootViewController作为动画层的superview/superlayer
[[[[UIApplication sharedApplication] rootViewController] view] layer addSublayer:myLayer];
我正在尝试使用[[[UIApplication sharedApplication]keyWindow].layer addSublayer:myLayer];但是现在有没有办法在动画播放到一半的时候推下一个视频控制器;我假设你的整个演示动画的前半部分实际上是一个完整的动画,如上文所述。
