獲取iOS設備當前鏈接的wifi名稱

首先須要引入如下倆個框架

#import <SystemConfiguration/SystemConfiguration.h>

#import <SystemConfiguration/CaptiveNetwork.h>

+ (NSString *)getPhoneConnectedWifiName {

NSArray *ifs = (__bridge id)CNCopySupportedInterfaces();

// NSLog(@"%s: Supported interfaces: %@", __func__, ifs);

id info = nil;

for (NSString *ifnam in ifs) {

info = (__bridgeid)CNCopyCurrentNetworkInfo((CFStringRef)CFBridgingRetain(ifnam));

if (info && [info count]) {

break;

}

}

if ([info isKindOfClass:[NSDictionary class]]) {

// DDLogDebug(@"getPhoneConnectedWifiName:%@", [info objectForKey:@"SSID"]);

return [info objectForKey:@"SSID"];

}

return [NSString string];

}
