The scenario can be addressed using MQTT Protocol within the Wi-Fi network. You will have to set up an MQTT Broker within the network and Make an MQTT Client in your iOs App. You can subscribe the MQTT Client to the MQTT broker on a topic same as GCM works and use MQTT Broker to send Push Notification to topics subscribed by MQTT Clients.
