我想检查VPN连接是否存在。 我在Swift中找到了代码,但无法在Objective-C中使用NEVPNStatus:
func checkNEStatus( status:NEVPNStatus ) {
switch status {
case NEVPNStatus.Invalid:
print("NEVPNConnection: Invalid")
case NEVPNStatus.Disconnected:
print("NEVPNConnection: Disconnected")
case NEVPNStatus.Connecting:
print("NEVPNConnection: Connecting")
case NEVPNStatus.Connected:
print("NEVPNConnection: Connected")
case NEVPNStatus.Reasserting:
print("NEVPNConnection: Reasserting")
case NEVPNStatus.Disconnecting:
print("NEVPNConnection: Disconnecting")
}
}
我正在为Objective-C使用以下代码:但是在某些中文网络设备中它不起作用。如果网络仍未使用vpn,他们将发送“ TUN”。
- (BOOL)isVPNConnected
{
NSDictionary *dict = CFBridgingRelease(CFNetworkCopySystemProxySettings());
NSArray *keys = [dict[@"__SCOPED__"]allKeys];
NSLog(@"keys==>%@",keys);
for (NSString *key in keys) {
if ([key rangeOfString:@"tap"].location != NSNotFound ||
[key rangeOfString:@"tun"].location != NSNotFound ||
[key rangeOfString:@"ipsec"].location != NSNotFound ||
[key rangeOfString:@"ppp"].location != NSNotFound){
return YES;
}
}
return NO;
}

在ViewDidLoad中添加观察者以获取VPN状态。
self.vpnManager.loadFromPreferences { (error) in
if error != nil {
print(error.debugDescription)
}
else{
print("No error from loading VPN viewDidLoad")
}
}
notificationObserver = NSNotificationCenter.defaultCenter().addObserverForName(NEVPNStatusDidChangeNotification, object: nil , queue: nil) {
notification in
print("received NEVPNStatusDidChangeNotification")
let nevpnconn = notification.object as! NEVPNConnection
let status = nevpnconn.status
self.checkNEStatus(status)
}
