iOS 获取当前Wifi的 名称 SSID

首先添加框架:SystemConfiguration.framework

[objc] view
plaincopy

#import <SystemConfiguration/CaptiveNetwork.h>

- (NSString *)currentWifiSSID {

// Does not work on the simulator.

NSString *ssid = nil;

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

for (NSString *ifnam in ifs) {

NSDictionary *info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);

if (info[@"SSID"]) {

ssid = info[@"SSID"];

}

}
