    view.backgroundColor = [UIColor redColor];

    view.layer.cornerRadius = 10;

    view.layer.masksToBounds=YES;

    UIView *bgShadowView = [[UIView alloc]initWithFrame:view.frame];

    [self.view addSubview:bgShadowView];

    bgShadowView.layer.shadowColor = [UIColor lightGrayColor].CGColor;

    bgShadowView.layer.shadowOffset = CGSizeMake(5, 5);

    bgShadowView.layer.shadowOpacity = 1;

    bgShadowView.layer.shadowRadius = 9.0;

    bgShadowView.layer.cornerRadius = 9.0;

    bgShadowView.clipsToBounds = NO;

    [bgShadowView addSubview:view];
