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)

释放双眼,带上耳机,听听看~!

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

Demo地址


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

https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/Hotspot_Network_Subsystem_Guide/Contents/Introduction.html#//apple_ref/doc/uid/TP40016639

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。

NSMutableDictionary* options = [[NSMutableDictionary alloc] init];
[options setObject:@"我是副标题" forKey:kNEHotspotHelperOptionDisplayName];
dispatch_queue_t queue = dispatch_queue_create("com.myapp.ex", NULL);
BOOL returnType = [NEHotspotHelper registerWithOptions:options queue:queue handler: ^(NEHotspotHelperCommand * cmd) {
NEHotspotNetwork* network;
NSLog(@"COMMAND TYPE:   %ld", (long)cmd.commandType);
[cmd createResponse:kNEHotspotHelperResultAuthenticationRequired];
if (cmd.commandType == kNEHotspotHelperCommandTypeEvaluate || cmd.commandType ==kNEHotspotHelperCommandTypeFilterScanList) {
NSLog(@"WIFILIST:   %@", cmd.networkList);
for (network  in cmd.networkList) {
NSLog(@"COMMAND TYPE After:   %ld", (long)cmd.commandType);
if ([network.SSID isEqualToString:@"ssid"]|| [network.SSID isEqualToString:@"WISPr Hotspot"]) {
double signalStrength = network.signalStrength;
NSLog(@"Signal Strength: %f", signalStrength);
[network setConfidence:kNEHotspotHelperConfidenceHigh];
[network setPassword:@"password"];
NEHotspotHelperResponse *response = [cmd createResponse:kNEHotspotHelperResultSuccess];
NSLog(@"Response CMD %@", response);
[response setNetworkList:@[network]];
[response setNetwork:network];
[response deliver];
}
}
}
}];
NSLog(@"result :%d", returnType);
NSArray *array = [NEHotspotHelper supportedNetworkInterfaces];
NSLog(@"wifiArray:%@", array);
NEHotspotNetwork *connectedNetwork = [array lastObject];
NSLog(@"supported Network Interface: %@", connectedNetwork);
