2016-04-20 08:28:44.860 prueba8[6090:2016802] The generated device token string is : ef7a4061378a5f7daa007671b1f86d26b5ab9a7b0a3ccdb12db6c8d6103b0fc8

i print de device token, and why the device token is invalid?, because i create all the certificates that are required, and i follow step by step the tutorial in your page.
