最近公司社区项目中要用到或者社区周围WiFi列表以及信号强度，好多网友说实现不了讨论区

iOS 获取系统wifi列表,wifi信号强度,并给wifi设置密码,标签(副标题)
iOS 无法获取 WiFi 列表？一定是因为你不知道这个框架
9.0以前获取需要引入
#import<SystemConfiguration/CaptiveNetwork.h>
+ (NSString *)getWifiName{
NSString *wifiName = nil;
CFArrayRef wifiInterfaces = CNCopySupportedInterfaces();
if (!wifiInterfaces) {
return @"未知";
}
NSArray *interfaces = (__bridge NSArray *)wifiInterfaces;
for (NSString *interfaceName in interfaces) {
CFDictionaryRef dictRef = CNCopyCurrentNetworkInfo((__bridge CFStringRef)(interfaceName));
if (dictRef) {
NSDictionary *networkInfo = (__bridge NSDictionary *)dictRef;
wifiName = [networkInfo objectForKey:(__bridge NSString *)kCNNetworkInfoKeySSID];
CFRelease(dictRef);
}
}
CFRelease(wifiInterfaces);
return wifiName;
}
9.0以后获取需要引入
import <NetworkExtension/NetworkExtension.h>
但在应用中需要添加icloud containers
NSArray * networkInterfaces = [NEHotspotHelper supportedNetworkInterfaces];
NSLog(@"Networks %@",networkInterfaces);
//获取wifi列表
for(NEHotspotNetwork *hotspotNetwork in [NEHotspotHelper supportedNetworkInterfaces]) {
NSString *ssid = hotspotNetwork.SSID;
NSString *bssid = hotspotNetwork.BSSID;
BOOL secure = hotspotNetwork.secure;
BOOL autoJoined = hotspotNetwork.autoJoined;
double signalStrength = hotspotNetwork.signalStrength;}
应用程序的Info.plist必须添加一个包含“remote-notification”的UIBackgroundModes数组.
应用程序必须设置“com.apple.developer.networking.HotspotHelper’作为它的权利之一。
该权利的值是一个布尔值true要申请这个权利，请发送E-MAIL到networkextension@apple.com更多信息请参阅苹果的Hotspot Network Subsystem Programming Guide
申请链接 ：https://developer.apple.com/contact/network-extension/
详阅官方文档： https://developer.apple.com/reference/networkextension/nehotspothelper
Register a Hotspot Helper
+ (BOOL)registerWithOptions:(NSDictionary*)options queue:(dispatch_queue_t)queue handler:(NEHotspotHelperHandler)handler
@param options
kNEHotspotHelperOptionDisplayName ：WIFI的注释tag字符串// 此处设置的内容会在WiFi列表中每个WiFi下边展示出来
@param queue dispatch_queue_t 用来调用handle的block
@param handler NEHotspotHelperHandler block 用于执行处理 helper commands.
@return 注册成功YES, 否则NO.
@discussion 一旦这个API调用成功，应用程序有资格在后台启动，并参与各种热点相关的功能。 当应用程序启动此方法应该调用一次。再次调用它会不会产生影响，并返回NO。
Manage Hotspot Networks
+ (BOOL)logoff:(NEHotspotNetwork *)network
@param network 对应当前关联的WiFi网络NEHotspotNetwork
@return 注销命令已成功进入队列YES, 否则NO.
@discussion 调用此方法使kNEHotspotHelperCommandTypeLogoff型的NEHotspotHelperCommand向应用程序发出的“handler”模块 网络参数必须符合当前关联的WiFi网络，即它必须来自对NEHotspotHelperCommand网络属性或方法supportedInterfaces
+ (NSArray *)supportedNetworkInterfaces
@return 如果没有网络接口被管理，返回nil。否则，返回NEHotspotNetwork对象数组。
@discussion 每个网络接口由NEHotspotNetwork对象表示。当前返回的数组包含一个NEHotspotNetwork对象代表Wi-Fi接口。
这种方法的主要目的是当没有得到一个命令来处理它时，让一个热点助手偶尔提供在UI里其准确的状态。 此方法加上NEHotspotNetwork的isChosenHelper方法允许应用程序知道它是否是当前处理的网络。
