9.0以后獲取需要引入import <NetworkExtension/NetworkExtension.h>
但在應(yīng)用中需要添加icloud containers

NSLog(@"Networks %@",networkInterfaces);
//獲取wifi列表

NSString *ssid = hotspotNetwork.SSID;
NSString *bssid = hotspotNetwork.BSSID;
BOOL secure = hotspotNetwork.secure;
BOOL autoJoined = hotspotNetwork.autoJoined;
double signalStrength = hotspotNetwork.signalStrength;}
應(yīng)用程序的Info.plist必須添加一個(gè)包含“remote-notification”的UIBackgroundModes數(shù)組.
應(yīng)用程序必須設(shè)置“com.apple.developer.networking.HotspotHelper'作為它的權(quán)利之一。
該權(quán)利的值是一個(gè)布爾值true要申請(qǐng)這個(gè)權(quán)利，請(qǐng)發(fā)送E-MAIL到networkextension@apple.com更多信息請(qǐng)參閱蘋果的Hotspot Network Subsystem Programming Guide

這種方法的主要目的是當(dāng)沒(méi)有得到一個(gè)命令來(lái)處理它時(shí)，讓一個(gè)熱點(diǎn)助手偶爾提供在UI里其準(zhǔn)確的狀態(tài)。 此方法加上NEHotspotNetwork的isChosenHelper方法允許應(yīng)用程序知道它是否是當(dāng)前處理的網(wǎng)絡(luò)。
