//Step 1
ApnsChannelFactory apnsChannelFactory = Apns4j.newChannelFactoryBuilder()
.keyStoreMeta("${path to your keystore}")
.keyStorePwd("${keystore password}")
.build();

//Setp 2
ApnsChannel apnsChannel = apnsChannelFactory.newChannel();

//Step 3 create & init notify payload
ApnsPayload apnsPayload = Apns4j.newPayload()
        .alertTitle("Title")
        .alertBody("Pushed by apns4j")
        .sound("default");

//Step 4 send via channel
apnsChannel.send("${target device token}", apnsPayload);

//Step 5 in the end, apnsChannel can be Recycle and Reuse 
apnsChannel.close();
