iOS获取当前连接的WiFi以及IP地址
导入头文件
#import#import #import
核心代码:
+(nullableNSString*)getCurrentLocalIP { NSString*address=nil; structifaddrs*interfaces=NULL; structifaddrs*temp_addr=NULL; intsuccess=0; //retrievethecurrentinterfaces-returns0onsuccess success=getifaddrs(&interfaces); if(success==0){ //Loopthroughlinkedlistofinterfaces temp_addr=interfaces; while(temp_addr!=NULL){ if(temp_addr->ifa_addr->sa_family==AF_INET){ //Checkifinterfaceisen0whichisthewificonnectionontheiPhone if([[NSStringstringWithUTF8String:temp_addr->ifa_name]isEqualToString:@"en0"]){ //GetNSStringfromCString address=[NSStringstringWithUTF8String:inet_ntoa(((structsockaddr_in*)temp_addr->ifa_addr)->sin_addr)]; } } temp_addr=temp_addr->ifa_next; } } //Freememory freeifaddrs(interfaces); returnaddress; }
+(nullableNSString*)getCurreWiFiSsid{ NSArray*ifs=(__bridge_transferid)CNCopySupportedInterfaces(); NSLog(@"Supportedinterfaces:%@",ifs); idinfo=nil; for(NSString*ifnaminifs){ info=(__bridge_transferid)CNCopyCurrentNetworkInfo((__bridgeCFStringRef)ifnam); NSLog(@"%@=>%@",ifnam,info); if(info&&[infocount]){break;} } return[(NSDictionary*)infoobjectForKey:@"SSID"]; }
