Question

我正在尝试在iOS设备上初始化JmDNS，使用以下行获取地址：

InetAddress adr = InetAddress.getLocalHost();

它在iphone模拟器中工作正常，但是当在物理iOS设备上测试时，这会导致带有stacktrace的UnknownHostException：

java.net.UnknownHostException: Unable to resolve host "#{name of iphone}": nodename nor servname provided, or not known
at libcore.io.GaiException.rethrowAsUnknownHostException(GaiException.java)
at java.net.InetAddress.lookupHostByName(InetAddress.java)

我已经阅读了建议说要传递＆＃34; 127.0.0.1＆＃34;作为地址，但当其他设备试图通过该IP连接到它时，这不起作用。我不确定该怎么做 - 我肯定需要获取本地IP地址，但我不知道如何获得它。这似乎与roboVM有关，但我不完全确定。也许有人可以对此有所了解？

自己想出来。显然，iOS会阻止您通过getLocalHost获取本地IP地址。我不得不使用RoboVM桥来插入Objective-C脚本来执行此操作：http://blog.robovm.org/2013/08/support-for-objective-c-blocks.html
