Test Connection over Wifi only iOS
提问by Charles Vincent
I have a method implemented thats tests the internet connection in my iOS app. The problem is, I only want the method to test the internet connection over wifi, not cellular. How do I do that? :-) PS I'm using the latest version of Xcode & iOS 6.
我实现了一种方法来测试我的 iOS 应用程序中的互联网连接。问题是，我只想要通过 wifi 测试互联网连接的方法，而不是蜂窝网络。我怎么做？:-) PS 我使用的是最新版本的 Xcode 和 iOS 6。
NSURL *scriptUrl = [NSURL URLWithString:@"http://10.247.245.87/stores/test.html"];
NSData *data = [NSData dataWithContentsOfURL:scriptUrl];
if (data != nil){
UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Success"
message: @"You're connected to the server"
delegate: self
cancelButtonTitle: @"Close"
otherButtonTitles:nil];
//Show Alert On The View
[alert show];
}
else {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Connection Failed"
message: @"Please connect to network and try again"
delegate: self
cancelButtonTitle: @"Close"
otherButtonTitles:nil];
//Show Alert On The View
[alert show];
}

Have you looked into the Reachability class?
你有没有研究过 Reachability 类？

It will probably provide you with a lot more flexibility and why roll your own if Apple has already done the work :) Hope this helps!
它可能会为您提供更多的灵活性，如果 Apple 已经完成了这项工作，为什么还要自己动手:) 希望这会有所帮助！

Check Tony Million Reachability class
There must be a isReachableViaWiFimethod you can check wifi only
必须有一种isReachableViaWiFi方法可以检查wifi
// allocate a reachability object
Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];
// tell the reachability that we DONT want to be reachable on 3G/EDGE/CDMA
reach.reachableOnWWAN = NO;
