Answer 1

Just call this method when your collectionviewcell click

[self animateZoomforCell:cell]; // pass cell as collectionviewcell

-(void)animateZoomforCell:(UICollectionViewCell*)zoomCell
{
    [UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{

        zoomCell.transform = CGAffineTransformMakeScale(1.6,1.6);
    } completion:^(BOOL finished){
    }];
}
-(void)animateZoomforCellremove:(UICollectionViewCell*)zoomCell
{
    [UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{

        zoomCell.transform = CGAffineTransformMakeScale(1.0,1.0);
    } completion:^(BOOL finished){
    }];
}

Answer 2

In swift 3 based on Himanshu Moradiya solution:

 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)

}
