UIImageView *imgvPhoto  = [UIImageView alloc] init];

    layer.borderColor = [[UIColor whiteColor] CGColor];
    layer.borderWidth = 5.0f;
//添加四个边阴影
    _imgvPhoto.layer.shadowColor = [UIColor blackColor].CGColor;
    _imgvPhoto.layer.shadowOffset = CGSizeMake(0, 0);
    _imgvPhoto.layer.shadowOpacity = 0.5;
    _imgvPhoto.layer.shadowRadius = 10.0;

    _imgvPhoto.layer.shadowOffset = CGSizeMake(4, 4);
    _imgvPhoto.layer.shadowOpacity = 0.5;
    _imgvPhoto.layer.shadowRadius = 2.0;

//设置layer  

CALayer *layer=[backView layer];
