You could do it this way :

Add an indicator to your view, place it at the center of your imageview

    UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
    [indicator startAnimating];
    [indicator setCenter:self.imageView.center];
    [self.contentView addSubview:indicator];

Remove the indicator from the superview in the block's succes method.

    [_imageView setImageWithURL:[NSURL URLWithString:anURL]
                       success:^(UIImage *image) {
                           [indicator removeFromSuperview];
                       }
                       failure:^(NSError *error) {

                       }];
}

Of course you could make a nice subclass for this

Activity Indicator is a view and I suppose your placeholder image is only an image.

If sdwebimage doesn't give you the possibility adding view instead of placeholder image, the best way for you will be to use an animated image of an activity indicator.
