This is an example of how to use apns4erl with a pool of connections. We are using worker_pool for creating the pool.
After cloning this repo in your local you must replace the priv/cert2.pem and priv/key2-noenc.pem files by your own provided by Apple.
You need to replace the apns-topic in the module apns_pool:push/2 also:
push(DeviceId, Message) ->
Notification = create_notification(Message),
ApnsTopic = <<"com.inaka.myapp">>, % Replace by your own topic
wpool:call(pool_name(), {push, DeviceId, ApnsTopic, Notification}).Now the configuration is done, lets compile:
$ rebar3 compile
and run
$ erl erl -pa _build/default/lib/*/ebin -s apns_pool
Erlang/OTP 19 [erts-8.3] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

you must wait until the last message is printed (apns_pool started), it could take some seconds until apns_pool loads completely.
You need a device id and calling apns_pool:push/2 function:
1> DeviceId = <<"bd5c3ad01bbe4d884bf2fe8801ed77e94a71bc2e9de937c84f745f54eb4cb2f4">>.
<<"bd5c3ad01bbe4d884bf2fe8801ed77e94a71bc2e9de937c84f745f54eb4cb2f4">>
2> apns_pool:push(DeviceId, <<"hello from a pool">>).
{200,
[{<<"apns-id">>,<<"1EF4ED9F-42FC-BA8B-450F-3BF6B09C72CB">>}],
no_body}
Thats all!
