使用wifi網絡的iOS位置

Question

我需要知道是否可以在iOS中使用WiFi網絡獲取用戶位置。

我閱讀有關該方法的顯著位置的變化，但我不知道這是否是必要的，用戶在去設備檢測周圍的事件的新的wifi網絡觸發連接到無線網絡或乾脆。

正如你所看到的我不知道這個問題，任何人都可以指導我一點？

Used Reachability class 
@property (nonatomic) Reachability *hostReachability; 
@property (nonatomic) Reachability *internetReachability; 
@property (nonatomic) Reachability *wifiReachability; 

Call below method in didFinishLaunchingWithOptions 
-(void)makeConnectionOverRechability { 

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reachabilityChanged:) name:kReachabilityChangedNotification object:nil]; //When intenet connectivity change this method call 

    NSString *remoteHostName = @"www.apple.com"; 
    self.hostReachability = [Reachability reachabilityWithHostName:remoteHostName]; 
    [self.hostReachability startNotifier]; 
    [self updateInterfaceWithReachability:self.hostReachability]; 

    self.internetReachability = [Reachability reachabilityForInternetConnection]; 
    [self.internetReachability startNotifier]; 
    [self updateInterfaceWithReachability:self.internetReachability]; 

    self.wifiReachability = [Reachability reachabilityForLocalWiFi]; 
    [self.wifiReachability startNotifier]; 
    [self updateInterfaceWithReachability:self.wifiReachability]; 

} 

#pragma mark- 
#pragma mark Internect Connectivity 
-(BOOL)checkInternetConnection 
{ 
    Reachability *reach = [Reachability reachabilityWithHostName:@"www.google.com"]; 
    NetworkStatus internetStatus = [reach currentReachabilityStatus]; 
    if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN)) 
    { 
     return internetStatus; 
    } 
    return internetStatus; 
} 

- (void) reachabilityChanged:(NSNotification *)note 
{ 
    Reachability* curReach = [note object]; 
    NSParameterAssert([curReach isKindOfClass:[Reachability class]]); 
    [self updateInterfaceWithReachability:curReach]; 
} 

- (void)updateInterfaceWithReachability:(Reachability *)reachability 
{ 
    if (reachability == self.hostReachability) 
    { 

    } 
    if (reachability == self.internetReachability) 
    { 
     [self configureTextField:reachability]; 
    } 

    if (reachability == self.wifiReachability) 
    { 
     [self configureTextField:reachability]; 
    } 
} 

- (void)configureTextField:(Reachability *)reachability 
{ 
    NetworkStatus netStatus = [reachability currentReachabilityStatus]; 

//check here only wifi connection 

    switch (netStatus) 
    { 
     case NotReachable: { 
      NSLog(@"not Connected+++++++++++"); 

      break; 
     } 
     case ReachableViaWWAN: { 
      NSLog(@"Connected"); 
         break; 
     } 
     case ReachableViaWiFi: { 
      NSLog(@"Connected"); 

      } 
      break; 
     } 
}
