一步一步跟下去发现
QNDnsManager.m:110
return [_sorter sort:ips]; 中 _sorter是nil
QNDnsManager.m:189
init方法从来没有被执行
(instancetype)init:(NSArray )resolvers networkInfo:(QNNetworkInfo )netInfo sorter:(id<QNIpSorter>)sorter;
这个定义就没有被调用的地方！坑爹啊！
自己解决了，
QNConfiguration:44
d = [[QNDnsManager alloc] init:[NSArray arrayWithObjects:r1,r2, r3, nil] networkInfo:[QNNetworkInfo normal ]];
->
d = [[QNDnsManager alloc] init:[NSArray arrayWithObjects:r1,r2, r3, nil] networkInfo:[QNNetworkInfo normal ] sorter:nil];
