"IOS" gets the WiFi name (i.e. SSID)

IOS get WiFi SSID name

SSID full service Set IDentifier, that is, the public name of the WiFi network. iOS 4.1 or later provides a public way to get that information.

First add a frame: systemconfiguration.framework

1 #import<SystemConfiguration/CaptiveNetwork.h>2- (ID) Fetchssidinfo3 {4Nsarray *ifs = (ID) cncopysupportedinterfaces (); 5NSLog (@"%s:supported interfaces:%@", __func__, IFS); 6     IDinfo =Nil;7      for(NSString *ifnaminchIFS)8     { 9info = (ID) Cncopycurrentnetworkinfo ((cfstringref) Ifnam); TenNSLog (@"%s:%@ =%@", __func__, Ifnam, info);  One         if(Info &&[Info count]) A         {  -             Break;  -         }  the [info release]; -     } - [IFS release]; -    return[Info autorelease]; + } -  +   A-(NSString *) Currentwifissid { at     //Does not work on the simulator. -NSString *ssid =Nil; -Nsarray *ifs = (ID) cncopysupportedinterfaces (); -NSLog (@"ifs:%@", IFS); -      for(NSString *ifnaminchIFS) { -Nsdictionary *info = (ID) Cncopycurrentnetworkinfo ((cfstringref) ifnam); inNSLog (@"dici:%@", [info AllKeys]); -         if(info[@"Ssidd"]) { toSSID = info[@"SSID"]; +              -         } the     } *     returnSSID; $ }Panax Notoginseng  -- (void) Viewdidload the { + [Super Viewdidload]; A      theTemplabel=[[uilabel Alloc]initwithframe:cgrectmake ( -, +, $, +)]; +Templabel.textalignment=Nstextalignmentcenter; - [Self.view Addsubview:templabel]; $Nsdictionary *ifs =[self fetchssidinfo]; $NSString *ssid = [[IFS Objectforkey:@"SSID"] lowercasestring]; -templabel.text=SSID; -   the}

ARC version:

1- (ID) Fetchssidinfo {2Nsarray *ifs = (__bridge_transferID) cncopysupportedinterfaces (); 3NSLog (@"supported interfaces:%@", IFS); 4     IDinfo =Nil;5      for(NSString *ifnaminchIFS)6     { 7info = (__bridge_transferID) Cncopycurrentnetworkinfo ((__bridge cfstringref) Ifnam); 8NSLog (@"%@ =%@", Ifnam, info); 9         if(Info &&[Info count])Ten         {  One              Break;  A         }  -    }  -    returninfo; the}

The effect is as follows:

IOS gets hotspot name and MAC address for WiFi

1 #import<SystemConfiguration/CaptiveNetwork.h>2 3NSString *ssid =@"Not Found";4 5NSString *macip =@"Not Found";6Cfarrayref MyArray =cncopysupportedinterfaces ();7 if(MyArray! =Nil) {8Cfdictionaryref mydict = Cncopycurrentnetworkinfo (Cfarraygetvalueatindex (MyArray,0));9     if(Mydict! =Nil) {TenNsdictionary *dict = (nsdictionary*) cfbridgingrelease (mydict); OneSSID = [Dict valueforkey:@"SSID"]; AMacIP = [Dict valueforkey:@"BSSID"]; -     } - } theUialertview *av =[[Uialertview alloc] Initwithtitle:ssid - Message:macip -                                             Delegate: Nil - Cancelbuttontitle:nil +Otherbuttontitles:@"OK", nil]; -[AV show];
