#import <SystemConfiguration/CaptiveNetwork.h>#import <CoreFoundation/CoreFoundation.h>- (NSString *)getCurrentWifiName{    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"];        }    }    NSLog(@"wifiName:%@", wifiName);    return wifiName;}
