AFNetworking提示3840 Unescaped control character around character XXX

处理办法：找到AFNetworking包中AFURLResponseSerialization.m文件在第250行修改代码如下：

 if (data.length > 0 && !isSpace) {

        NSString* sInvalid = [NSString stringWithUTF8String:[data bytes]];

               // 从服务器收到的类似上一行的数据

        sInvalid =  [sInvalid stringByReplacingOccurrencesOfString:@"\r" withString:@""];

        sInvalid = [sInvalid stringByReplacingOccurrencesOfString:@"\t" withString:@""];

        NSData *dataa = [[sInvalid stringByReplacingOccurrencesOfString:@"\n" withString:@""] dataUsingEncoding:NSUTF8StringEncoding];

        if (dataa == nil) {

            dataa = data;

        }

        responseObject = [NSJSONSerialization JSONObjectWithData:dataa options:self.readingOptions error:&serializationError];

    } else {

        return nil;

    }
