NSNetService工作正常，但无法获取hostName，解决导致错误 [英] NSNetService works fine, but can't get hostName, resolve causes error

问题描述

我正在使用Bonjour和NSNetService从我的iPhone发布服务器。这一切都按预期工作，我可以浏览我正在服务的页面等。但是，在iPhone上我想显示主机名（即URL，如myDevice.local。），这样一个人也可以进入在浏览器中手动设置地址（对于缺少bonjour发现服务的客户非常有用）。我的理解是调用方法[myNetService hostName]应该给我那个地址。但是，此调用始终返回nil。我在一些论坛上读到我首先应该解析该服务，但[myNetService resolve]和[myNetService resolveWithTimeout：10]都调用委托方法

I'm using Bonjour with an NSNetService to publish a server from my iPhone. It all works as expected, I can browse the pages I'm serving etc. However, on the iPhone I want to display the host name (i.e. the URL, like "myDevice.local."), so that one can also enter the address manually in a browser (useful for clients missing a bonjour discovery service). My understanding is that calling the method [myNetService hostName] should give me that address. However, this call always returns nil. I read on some forum that I first should resolve the service, however both [myNetService resolve] and [myNetService resolveWithTimeout:10] call the delegate method

- (void)netService:(NSNetService *)sender didNotResolve:(NSDictionary *)errorDict;

错误

{
    NSNetServicesErrorCode = -72003;
    NSNetServicesErrorDomain = 10;
}

这显然意味着它已经解决了。同样，当我可以使用该服务时，所有这一切都在发生。我也可以获得端口，域和服务类型。另一个奇怪的事情是调用[myNetService addresses]返回一个空数组。

which apparently means that it is already resolved. Again, all this is happening while i can use the service. Also I can get the port, the domain, and the type of the service. The only other strange thing is that the call [myNetService addresses] returns an empty array.

我正在使用SDK 3.1.3。有没有人知道我可能做错了什么？

I'm using SDK 3.1.3. Does anybody have an idea what I could be doing wrong?

推荐答案

你可以通过[[NSProcessInfo processInfo] hostName]获取主机名没有解决刚刚发布的网络服务。

You can get the hostname via [[NSProcessInfo processInfo] hostName] without resolving the netservice you just published.
