UIDragInteraction预览旋转

Question

我首先创建一个UIImageView 。 创建后，此UIImageView不会旋转，因此我将此状态称为Original Rotation 。 然后旋转UIImageView 。 图像现在有了旋转，我将此状态称为New Rotation 。 为了完成所有操作，我将图像拖到同一视图中的其他位置。

我目前有以下用于拖动的委托函数：

func dragInteraction(_ interaction: UIDragInteraction, itemsForBeginning session: UIDragSession) -> [UIDragItem] {
    let touchedPoint = session.location(in: self.view)
    if let touchedImageView = self.view.hitTest(touchedPoint, with: nil) as? UIImageView {
        let touchedImage = touchedImageView.image

        let itemProvider = NSItemProvider(object: touchedImage!)
        let dragItem = UIDragItem(itemProvider: itemProvider)
        dragItem.localObject = touchedImageView
        return [dragItem]
    }
    return []
}
func dragInteraction(_ interaction: UIDragInteraction, previewForLifting item: UIDragItem, session: UIDragSession) -> UITargetedDragPreview? {
    return UITargetedDragPreview(view: item.localObject as! UIImageView)
}
func dragInteraction(_ interaction: UIDragInteraction, willAnimateLiftWith animator: UIDragAnimating, session: UIDragSession) {
    session.items.forEach {(dragItem) in
        if let touchedImageView = dragItem.localObject as? UIView {
            touchedImageView.removeFromSuperview()
        }
    }
}

启动拖动过程后，正在拖动的图像会抬起，并且显示的预览将保留“ New Rotation 。 但是，当我开始移动手指并且预览开始随之移动时，预览会丢失New Rotation ，而显示Original Rotation 。 拖动时如何使预览保留“ New Rotation ？
