iOS 修改tableViewCell上面accessoryVi

iOS 在所需要创建的Cell和原生Cell相差不大并且需要accessoryView的图片自定义时，修改tableViewCell上面accessoryView的默认图片及位置

newsCell.accessoryView = ({
   UIImageView *imgV = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"listen_voise"]];
   CGRect frame = imgV.frame;
   frame.size.width = frame.size.width + 10 *SCALE_WIDTH;
   imgV.frame = frame;
   [imgV setContentMode:UIViewContentModeLeft];
   imgV;
});
