我正在开发图像编辑应用程序（调整大小、旋转、3d 变换）。如果我旋转图像然后进行 3D 变换。它将进入初始图像。否则我改变 3D 变换然后进行旋转，它也进入初始状态。

对于图像 3D 变换，我使用以下代码：

- (void)moveImage:(UIPanGestureRecognizer *)recognizer
{
        if ([recognizer respondsToSelector:@selector(translationInView:)]) {
            CGPoint translation = [(UIPanGestureRecognizer *)recognizer translationInView:recognizer.view.superview];

            CALayer *layer = self.layer;
            CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity;
            rotationAndPerspectiveTransform.m34 = 1.0 / 500.0;
            rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, - self.xTranslation / 50.0 * M_PI / 180.0f, 0.0f, 1.0f, 0.0f);
            layer.transform = rotationAndPerspectiveTransform;
            rotationAndPerspectiveTransform.m34 = - 1.0 / 500.0;
            rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, - self.yTranslation / 50.0 * M_PI / 180.0f, 1.0f, 0.0f, 0.0f);
            layer.transform = rotationAndPerspectiveTransform;
        }
 }

对于图像旋转，我使用以下代码：

- (void)rotateImage:(UIRotationGestureRecognizer *)recognizer
{
    if (state == RSImageViewStateResizing) {
        recognizer.view.transform = CGAffineTransformRotate(recognizer.view.transform, recognizer.rotation);
        recognizer.rotation = 0;
    }
}

我该如何解决这个问题。随时欢迎您的建议、示例代码、示例项目、任何 App Store 应用程序。提前致谢。任何人帮助我。

使用 CAAnimationGroup 将多个动画合二为一

CAAnimationGroup *theGroup = [CAAnimationGroup animation];
theGroup.animations=[NSArray arrayWithObject:resizeAnimation, rotationAnimation, 3d transformAnimation];// add here your CAAnimation reference and CATransform3D reference
[layer addAnimation:theGroup forKey:@"animatePosition"];
