# Happy DNS for Objective-C
[](http://weibo.com/qiniutek)

## 用途
调用系统底层Dns解析库，可以使用 114 等第三方 dns 解析，可以使用 Doh 协议的 Dns 解析方案，也可以集成 dnspod 等 httpdns。另外也有丰富的 hosts 域名配置。
## 安装
通过 CocoaPods
```ruby
pod "HappyDNS"
```
通过 Swift Package Manager (Xcode 11+)
```
App 对接:
File -> Swift Packages -> Add Package Dependency，输入 HappyDNS 库链接，选择相应版本即可
库链接: https://github.com/qiniu/happy-dns-objc
库对接:
let package = Package(
dependencies: [
.package(url: "https://github.com/qiniu/happy-dns-objc", from: "1.0.4")
],
// ...
)
```
## 运行环境
## 使用方法
＊ 返回 IP 列表
```
NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:[QNResolver systemResolver]];
[array addObject:[[QNResolver alloc] initWithAddress:@"119.29.29.29"]];
[array addObject:[QNDohResolver resolverWithServer:@"https://dns.alidns.com/dns-query"]];
QNDnsManager *dns = [[QNDnsManager alloc] init:array networkInfo:[QNNetworkInfo normal]];
NSArray *records = [dns queryRecords:@"www.qiniu.com"];
```
＊ url 请求，返回一个IP 替换URL 里的domain
```
NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:[QNResolver systemResolver]];
[array addObject:[[QNResolver alloc] initWithAddress:@"119.29.29.29"]];
QNDnsManager *dns = [[QNDnsManager alloc] init:array networkInfo:[QNNetworkInfo normal]];
NSURL *u = [[NSURL alloc] initWithString:@"rtmp://www.qiniu.com/abc?q=1"];
NSURL *u2 = [dns queryAndReplaceWithIP:u];
```
* 兼容 getaddrinfo, 方便底层 C 代码接入
```
static QNDnsManager *dns = nil;
dns = [[QNDnsManager alloc] init:@[ [QNResolver systemResolver] ] networkInfo:nil];
[QNDnsManager setGetAddrInfoBlock:^NSArray *(NSString *host) {
return [dns query:host];
}];
struct addrinfo hints = {0};
struct addrinfo *ai = NULL;
int x = qn_getaddrinfo(host, "http", &hints, &ai);
qn_freeaddrinfo(ai); // 也可以用系统的freeaddrinfo, 代码一致，不过最好用这个
```
### 运行测试
``` bash
$ xctool -workspace HappyDNS.xcworkspace -scheme "HappyDNS_Mac" -sdk macosx -configuration Release test -test-sdk macosx
```
### 指定测试
可以在单元测试上修改，熟悉使用
``` bash
```
## 常见问题
- 如果碰到其他编译错误，请参考 CocoaPods 的 [troubleshooting](http://guides.cocoapods.org/using/troubleshooting.html)
- httpdns 在**ios8** 时不支持 nat64 模式下 IP 直接访问url，原因是 NSUrlConnection 不支持。无论是用http://119.29.29.29/d 还是http://[64:ff9b::771d:1d1d]/d 都不行，此时可以使用localdns方式。
- 如果软件有国外的使用情况时，建议初始化程序采取这样的方式
```Objective-C
QNDnsManager *dns;
if([QNDnsManager needHttpDns]){
NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:[[QNResolver alloc] initWithAddress:@"119.29.29.29"]];
[array addObject:[QNResolver systemResolver]];
dns = [[QNDnsManager alloc] init:array networkInfo:[QNNetworkInfo normal]];
}else{
NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:[QNResolver systemResolver]];
[array addObject:[[QNResolver alloc] initWithAddress:@"114.114.114.114"]];
dns = [[QNDnsManager alloc] init:array networkInfo:[QNNetworkInfo normal]];
}
```
