Can activityIndicator and placeholder image be used at the same time? #68

It seems the followings don't work for me.

cell.asyncImageView.image = [UIImage imageNamed:@"avatar.png"];
cell.asyncImageView.showActivityIndicator = YES;
[cell.asyncImageView setImageURL: url];

or

cell.asyncImageView.showActivityIndicator = YES;
cell.asyncImageView.image = [UIImage imageNamed:@"avatar.png"];
[cell.asyncImageView setImageURL: url];

Any suggestions? Thanks.
