ApplePush

ApplePush is a very simple implementation of the APNS (Apple Push Notification Service) protocol. It differs from the APNS gem by being able to push to different iOS apps from the same Ruby application.

$ gem install apple-push

require 'apple-push'
ApplePush.host = 'gateway.push.apple.com' 
ApplePush.port = 2195

In Keychain access export your certificate as a p12. Then run the following command to convert it to a .pem

openssl pkcs12 -in cert.p12 -out cert.pem -nodes -clcerts

Then store the PEM data in your database or in a file.

ApplePush.send_notification(pem, device_token, 'Hello, world!')
ApplePush.send_notification(pem, device_token, :alert => 'Hello, world!', :badge => 1, :sound => 'default')
ApplePush.send_notification(pem, device_token, :alert => 'Hello, world!', :badge => 1, :sound => 'default', :other => { :foo => 'bar' })

The pem parameter can either be the path to a .pem file or the PEM data it self, retrieved from a database for example. If the PEM certificate is encrypted with a password you should pass an array with the pem and the password instead of just the pem.

The device_token can either be binary data, or Base64 encoded.
