在iOS5中需要ARC的可达性版本 [英] Need Reachability version for ARC in iOS5

问题描述

在iOS5中使用Apple的Reachability代码我收到一堆编译错误，如下所示。关于这里发生了什么的任何想法？我正在使用ARC所以我稍微编辑了标准代码以删除 autorelease / retain 和 NSAutoReleasePool 。

Using Apple's Reachability code in iOS5 I get a bunch of compilation errors as shown below. Any ideas on what is happening here? I'm using ARC so I have edited the standard code slightly to remove autorelease/retain and the NSAutoReleasePool.

架构armv7的未定义符号：

Undefined symbols for architecture armv7:

ld：symbol （s）找不到架构armv7 clang：错误：链接器
命令失败，退出代码为1（使用-v查看调用）

ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

有没有人在iOS5下为ARC提供可行的可达性代码？

Does anyone have workable Reachability code for ARC under iOS5?

推荐答案

我为ARC和iOS5编写了一个干净的'drop in'版本的可达性 - 你可以在这里找到它： https://github.com/tonymillion/Reachability
