我如何检查状态（无，WLAN，WLAN &蜂窝）我的应用程序，这样我就可以显示一个警示，提醒打开这个开关用户〜

Answer 1

我找到一个解决方案终于〜

：d

当Reachability是NotReachable，有2个的情况下，

1. 在WiFi没有连接
2. 的Apps Using WLAN & Cellular Setting 熄灭

如果我们能得到当前的WiFi的SSID，我们可以判断的WiFi连接和网络开关断开时〜

#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); 
    }
