图片的数据类型问题 URL

data type issue with image URL

我确定这很容易解决,但我似乎无法解决...

group[PF_GROUP_FEATURED] is just a database reference to a URL. I am trying to get these images to show up in my tableView cells.

我的错误是"incompatible pointer types sending UIImage to parameter type NSString.."

UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:group[PF_GROUP_LOGO]]]];
    cell.imageView.image = [UIImage imageNamed:image];

cell.imageView.image = image;

cell.imageView.image = 图片;
