如何检测iPhone上3G或Wi-Fi上运行的数据? [英] How to detect wheter running on 3G or Wi-Fi on iPhone?

问题描述

一些代码行?有经验吗?

Some lines of code? Any experience?

推荐答案

因为我做了一个非常简单的基于块的可到达性包装程序，该包装程序将所有过时的类似于C的可到达性代码剥离，并注入了更多的可可形式.

Since than I made a pretty simple block based Reachability wrapper that strips all the outdated C-like Reachability code, poured into a much more Cocoa form.

用法类似:

[EPPZReachability reachHost:hostNameOrIPaddress
               completition:^(EPPZReachability *reachability)
{
    if (reachability.reachableViaCellular) [self doSomeLightweightStuff];
}];

在它还可以与IP地址配合使用，事实证明这是一种非常罕见的可达性包装器功能.

It also works with IP addresses, which turned out to be a pretty rare Reachability wrapper feature.
