NSString *htm = [_finalizeModel.content stringByAppendingString:@""];
            NSString *htmStr = @"";
            NSString *htmString = [htmStr stringByAppendingString:htm];
//            NSString *d5 = [_finalizeModel.content stringByReplacingOccurrencesOfString:@"

进行替换
            NSString *htmlString = [htmString stringByReplacingOccurrencesOfString:@"
" withString:@""];//出现
进行替换
            NSAttributedString *d5 = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
            _neirongLabel.attributedText = d5;

如果后台返回的没有则需要拼接，反之不拼接。
