Question

如何在下圖中獲取Apps Using WLAN & Cellular Setting設置狀態？
我如何檢查狀態（無，WLAN，WLAN &蜂窩）我的應用程序，這樣我就可以顯示一個警示，提醒打開這個開關用戶〜

我找到一個解決方案終於〜

：d

當Reachability是NotReachable，有2個的情況下，

1. 在WiFi沒有連接
2. 的Apps Using WLAN & Cellular Setting 熄滅

如果我們能得到當前的WiFi的SSID，我們可以判斷的WiFi連接和網絡開關斷開時〜

#import <SystemConfiguration/CaptiveNetwork.h> 

    BOOL networkSwitchOff = NO; 
    Reachability *reach = [Reachability reachabilityForInternetConnection]; 
    NetworkStatus status = [reach currentReachabilityStatus]; 
    if(status==NotReachable){ //Reachability NotReachable 
     NSArray *supportedInterfaces = (__bridge_transfer id)CNCopySupportedInterfaces(); 
     id info = nil; 
     NSString *ssid = nil; 
     for (NSString *networkInfo in supportedInterfaces) { 
      info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)networkInfo); 
      if (info && [info count]) 
       break; 
     } 

     if (info) { 
      NSDictionary *dctySSID = (NSDictionary *)info; 
      //we can't get ssid if wifi is not connected 
      ssid = [dctySSID objectForKey:@"SSID"]; 
     } 
     networkSwitchOff = (ssid!=nil); 
    }
