如何在uicollectionview中放大单元格的内容

Question

在上图中，A，B，C，D，E是集合视图的每个自定义单元格，我想像c单元格一样逐个放大单元格。

有什么建议吗？

Answer 1

只需在您的collectionviewcell点击

时调用此方法

int width = view->verticalHeader()->width() + view->horizontalHeader()->width() + view->frameWidth()*2;
int height= view->horizontalHeader()->height() + view->verticalHeader()->height() + view->frameWidth()*2;

Answer 2

基于Himanshu Moradiya解决方案的 swift 3 ：

 func animateZoomforCell(zoomCell : UICollectionViewCell)
{
    UIView.animate(
        withDuration: 0.2,
        delay: 0,
        options: UIViewAnimationOptions.curveEaseOut,
        animations: {
                        zoomCell.transform = CGAffineTransform.init(scaleX: 1.2, y: 1.2)
            },
    completion: nil)
}
func animateZoomforCellremove(zoomCell : UICollectionViewCell)
{
    UIView.animate(
        withDuration: 0.2,
        delay: 0,
        options: UIViewAnimationOptions.curveEaseOut,
        animations: {
            zoomCell.transform = CGAffineTransform.init(scaleX: 1.0, y: 1.0)
    },
        completion: nil)

}
