确定iPhone互联网连接是否可用的最简单方法？ [英] Easiest way to determine whether iPhone internet connection is available?

问题描述

我希望确定iPhone上是否有互联网连接。对于应用程序来说无论是wifi还是EDGE或其他什么都无关紧要。

I am looking to determine whether an internet connection is available on the iPhone. It doesn't matter for the app whether it's wifi or EDGE or whatever.

使用SeismicXML示例中的代码似乎不起作用，而且Reachability示例代码来自Apple似乎对该应用程序有点过分...

Using the code from the SeismicXML example doesn't seem to work and the Reachability example code from Apple seems like overkill for the app...

有没有一种快速简便的方法来确定iPhone上的网络可用性？

Is there a quick and easy way to determine network availability on the iPhone?

谢谢，
Ben

Thanks, Ben

推荐答案

遵循以下3个简单步骤 -

步骤1：在项目中包含SystemConfiguration.framework框架

Step 1: Include "SystemConfiguration.framework" framework in your project

第2步：包含Apple的Reachability.h和Reachability.m来自可达性示例

Step 2: Included Apple's Reachability.h and Reachability.m from Reachability example

第3步：现在添加此项代码中任意位置的代码。

Step 3: Now add this code anywhere in your .m.

Reachability* wifiReach = [[Reachability reachabilityWithHostName: @"www.apple.com"] retain];
NetworkStatus netStatus = [wifiReach currentReachabilityStatus];

switch (netStatus)
{
    case NotReachable:
    {
        NSLog(@"Access Not Available");
        break;
    }

    case ReachableViaWWAN:
    {
        NSLog(@"Reachable WWAN");
        break;
    }
    case ReachableViaWiFi:
    {
        NSLog(@"Reachable WiFi");
        break;
    }
}
