ios - 有深度的摇摆动画

Question

在我的应用程序中，我有一个弹出横幅，每次用户从服务器收到通知时都会跳转，这个弹出窗口看起来像一个带有字符串的标志，附加到屏幕顶部(不是代码字符串，哈哈)。

我正在尝试实现摆动动画，但不是左右摆动!来回，所以底部 yz 点应该急剧变化，所以看起来弹出标志正在向用户移动，然后返回，依此类推....

我希望我的问题很清楚，这件事困扰了我很长时间.. 谢谢! !

所以我添加了一个图像(真的画得很糟糕，对此感到抱歉)，它描述了我试图达到的效果:

再次，对糟糕的绘图感到抱歉。

这是我到目前为止所做的代码:

// container
CALayer *container = [CALayer layer];
container.frame = CGRectMake(50, 50, 100, 100);
[self.view.layer addSublayer:container];


//Create a Plane

CALayer *purplePlane = [self addPlaneToLayer:container
                                        size:CGSizeMake(100, 100)
                                    position:CGPointMake(250, 150)
                                       color:[UIColor purpleColor]];



[container addSublayer:imageView.layer];


 //Apply transform to the PLANE
 CATransform3D t = CATransform3DIdentity;
 //Add perspective!!!
 t.m34 = 1.0/ -100;
 //t.m34 = 1.0/ -500;
 t = CATransform3DRotate(t, degToRad(45.0), 0, 1, 0);

 purplePlane.transform = t;


CATransform3D transform = CATransform3DIdentity;
// transform.m34 = 1.0 / -50;
container.transform = transform;

CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"transform"];
animation.values = [NSArray arrayWithObjects:

                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 0.8 * M_PI / 2, 100, 100, 0.2)],
                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 0 * M_PI / 2, 100, 100, 0.2)],
                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, -0.6 * M_PI / 2, 100, 1, 0.2)],
                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 0 * M_PI / 2, 100, 1, 0.2)],
                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 0.3 * M_PI / 2, 100, 1, 0.2)],
                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 0 * M_PI / 2, 100, 1, 0.2)],
                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, -0.1 * M_PI / 2, 100, 1, 0.2)],
                    [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 0 * M_PI / 2, 100, 1, 0.2)],



                    // [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 2 * M_PI / 2, 100, 1, 5)],
                    //   [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 3 * M_PI / 2, 100, 1, 100)],
                    //   [NSValue valueWithCATransform3D:CATransform3DRotate(transform, 4 * M_PI / 2, 100, 1, 100)],
                    nil];
animation.duration = 5;
[container addAnimation:animation forKey:animation.keyPath];

您会注意到，在我的代码中， View 向您摆动没有任何影响，这就是我要寻找的。

谢谢，干杯

听起来您正在寻找放大/缩小动画，例如:

UIView *theStrigViewThing = ...

[UIView animateWithDuration: 0.2 delay: 0.0 options: UIViewAnimationOptionCurveEaseIn animations:^{
            [theStrigViewThing setTransform: CGAffineTransformMakeScale(2.0f, 2.0f)];
        } completion:^(BOOL finished) {
            [UIView animateWithDuration: 0.2 delay: 0.0 options: UIViewAnimationOptionCurveEaseOut animations:^{
                [theStrigViewThing setTransform: CGAffineTransformIdentity];
            } completion:nil];
        }];
