属性

注解

此常量可用于注册 NSNotificationCenter 此通知的侦听器。 这是 NSString 而不是字符串,因为这些值可以用作某些本机库中的标记,而不是纯粹用于其实际字符串内容。 回调的“notification”参数包含特定于通知类型的额外信息。

// Lambda style
NSNotificationCenter.DefaultCenter.AddObserver (
        NEVpnManager.ConfigurationChangeNotification, (notification) => {Console.WriteLine ("Received the notification NEVpnManager", notification); }


// Method style
void Callback (NSNotification notification)
{
    Console.WriteLine ("Received a notification NEVpnManager", notification);
}

void Setup ()
{
    NSNotificationCenter.DefaultCenter.AddObserver (NEVpnManager.ConfigurationChangeNotification, Callback);
}
