-(NSString *)getDeviceSSID
{
    NSArray *ifs = (__bridge id)CNCopySupportedInterfaces();

    id info = nil;
    
    for (NSString *ifnam in ifs) {
        
        info = (__bridge id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
        
        if (info && [info count]) {
            
            break;
            
        }
        
    }
    
    NSDictionary *dctySSID = (NSDictionary *)info;
    NSString *ssid = [dctySSID objectForKey:@"SSID"];
    
    return ssid;
