Detect the name of wireless network
提问by Charles Vincent
Is it possible to run a method that will return the name of the wireless network that the user is connected to? Inside of my app I want to be able to return the name of the wireless network that the user is connected to.
是否可以运行一种方法来返回用户所连接的无线网络的名称？在我的应用程序内部，我希望能够返回用户连接到的无线网络的名称。

This worked perfect for me:
这对我来说很完美：
#import <SystemConfiguration/CaptiveNetwork.h>
CFArrayRef myArray = CNCopySupportedInterfaces();
CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
// NSLog(@"SSID: %@",CFDictionaryGetValue(myDict, kCNNetworkInfoKeySSID));
NSString *networkName = CFDictionaryGetValue(myDict, kCNNetworkInfoKeySSID);
if ([networkName isEqualToString:@"Hot Dog"])
{
self.storeNameController = [[StoreDataController alloc] init];
[self.storeNameController addStoreNamesObject];
}
else {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Connection Failed"
message: @"Please connect to the Hot Dog network and try again"
delegate: self
cancelButtonTitle: @"Close"
otherButtonTitles: nil];
[alert show];

From Developer.apple, you can use CNCopyCurrentNetworkInfo
从 Developer.apple，您可以使用CNCopyCurrentNetworkInfo
It Returns the current network info for a given network interface.
它返回给定网络接口的当前网络信息。
CFDictionaryRef CNCopyCurrentNetworkInfo (
CFStringRef interfaceName
);
It contains a dictionary that containing the interface's current network info. Ownership follows the Create Rule.
它包含一个字典，其中包含接口的当前网络信息。所有权遵循创建规则。
Note:Available in iOS 4.1 and later.
注意：适用于 iOS 4.1 及更高版本。
EXAMPLE:
例子：
This example will work fine in real device, It may crash in simulator.
这个例子在真实设备上可以正常工作，在模拟器中可能会崩溃。
Add SystemConfiguration.framework
添加SystemConfiguration.framework
ImportCaptiveNetworkheader same as below
导入CaptiveNetwork头与下面相同
#import <SystemConfiguration/CaptiveNetwork.h>
#import <SystemConfiguration/CaptiveNetwork.h>
Then write the below code.
然后编写下面的代码。
CFArrayRef myArray = CNCopySupportedInterfaces();
// Get the dictionary containing the captive network infomation
CFDictionaryRef captiveNtwrkDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
NSLog(@"Information of the network we're connected to: %@", captiveNtwrkDict);
NSDictionary *dict = (__bridge NSDictionary*) captiveNtwrkDict;
NSString* ssid = [dict objectForKey:@"SSID"];
NSLog(@"network name: %@",ssid);
or
或者
Using Bonjour, the application both advertises itself on the local network and displays a list of other instances of this application on the network
使用Bonjour，应用程序既在本地网络上宣传自己，又在网络上显示此应用程序的其他实例的列表

The BAD NEWS: 'CNCopyCurrentNetworkInfo' is deprecated: first deprecated in iOS 9.0- For captive network applications, this has been completely replaced by <NetworkExtension/NEHotspotHelper.h>. For other applications, there is no direct replacement. Please file a bug describing your use of this API to that we can consider your requirements as this situation evolves.
坏消息：'CNCopyCurrentNetworkInfo' 已被弃用：在 iOS 9.0 中首次被弃用- 对于强制网络应用程序，这已被 <NetworkExtension/NEHotspotHelper.h> 完全取代。对于其他应用程序，没有直接替换。请提交描述您使用此 API 的错误，以便我们可以随着这种情况的发展考虑您的要求。
The GOOD NEWS: although deprecated, it still works in iOS 9, AND it has been un-deprecated in iOS 10.
好消息：虽然已被弃用，但它仍可在 iOS 9 中使用，并且在 iOS 10 中未弃用。
It still works in iOS 13, but only if the app implements Location Services and the user authorizes their usage.
它仍然适用于 iOS 13，但前提是该应用程序实现了定位服务并且用户授权其使用。
