直接上代码

#import <ifaddrs.h>
#import <arpa/inet.h>
#import <SystemConfiguration/CaptiveNetwork.h>+ (NSString *)wifiName{NSString *wifiName = @"Not Found";CFArrayRef myArray = CNCopySupportedInterfaces();if (myArray != nil) {CFDictionaryRef myDict =CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));if (myDict != nil) {NSDictionary *dict = (NSDictionary*)CFBridgingRelease(myDict);wifiName = [dict valueForKey:@"SSID"];}}return wifiName;
}
