是否有可能在ios 9中获得wifi信号强度

Question

我想检查WIFI信号强度,以显示弱WIFI信号的某种消息.

我认为在iOS 8及更早版本中它是不可能的.

是否有可能在iOS 9中获得wifi信号强度？如果答案是肯定的那么如何？

Answer 1

是的,它可以在iOS 9中查看NEHotspotNetwork

Answer 2

将您的应用注册为Hotspot助手.(forums.developer.apple.com/message/30657#30657)

#import <NetworkExtension/NetworkExtension.h>

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;
}
