我可以查看wifi服务的状态吗？如果用户手机未连接到WiFi，则启用还是禁用。我需要它来创建用户警报，因为我需要WIFi状态为“ON”状态我的应用程序导航。

Answer 1

为此，您需要在项目中导入可达性类。

BOOL isConnectedProperly = ([[Reachability reachabilityForInternetConnection] currentReachabilityStatus] == ReachableViaWiFi);

Answer 2

Use Reachability Class for checking the network connection state


Reachability *internetReachable=[Reachability reachabilityForInternetConnection];    
if(internetReachable.currentReachabilityStatus == ReachableViaWiFi)
{
    wifiAvailable=YES;
}
else
{
// Show the alert to turn on wifi
}

Answer 3

使用代码apple提供https://developer.apple.com/iphone/library/samplecode/Reachability

Reachability *reachability = [Reachability reachabilityForInternetConnection];
[reachability startNotifier];

NetworkStatus status = [reachability currentReachabilityStatus];

if(status == NotReachable) 
{
    //No internet
}
else if (status == ReachableViaWiFi)
{
    //WiFi
}
else if (status == ReachableViaWWAN) 
{
    //3G
}
