Yes, thats the first thing that was coming to my mind when I was called to implement push notifications in an iOS app, and Im pretty confident that it has been coming to yours as well.
Easy Apns Provider Easy Apns Provider Series Of StepsAnd not because its difficult to use push notifications, its just all that series of steps required prior to even be able to test a single push notification and cause eventually a huge confusion to almost all developers.
![]() But, lets hold on a minute, and lets take things from the beginning. As an iOS developer, you know that iOS supports two types of notifications: Local and Push (or Remote). In the former case, notifications are registered and scheduled by the app itself, and theyre really easy to be implemented. ![]() They are triggered by another service (called provider ), most often a web server, and theyre usually targeting to multiple devices simultaneously. With push notifications, app creators can send messages to users when necessary, either in random times or scheduled, and either with a customized (personalised) or a default message body. Here is a good resource for some general information about Apple Push Notifications. That is through the Apple Push Notification Servers, or simply APN servers. Those servers actually route push notifications to the proper devices, and messages are normally delivered within a few seconds by the time theyre sent by the provider. In simple words, the lifecycle of a remote notification can be summed up as shown next. Those steps are divided in two general categories: The programming preparation, and the production of various certificates, provisioning profiles and more. ![]() Easy Apns Provider Easy Apns Provider Mac OS Keychain AccessThe confusing is the second part, where a number of other actions are necessary to be taken in various places, such as the Mac OS Keychain Access app, the project, and the Apple Developer Member Center portal. If you manage to successfully receive sandboxed notifications in your app and at the same time you have taken all the actions that were shortly mentioned above properly, then you can be sure that live push notifications will work too. Needless to say that Apple provides test servers for sending sandboxed notifications, and its not the production APNs for that purpose. Hopefully, this tutorial will be your guide the next time that youll need to add push notifications to your app, but most importantly, it will take you out of any hassle and confusion resulting from the push notifications prerequisites. Also, quite often I give you a starter project to begin with, but not this time. Thats because were not meant to use it for testing an in-app functionality, but to only as a target for our push notifications. Easy Apns Provider Easy Apns Provider How To Generate ItIf you need to use a Code Signing Request (CSR) file, read the next part on how to generate it. To refresh your memory about notifications take a look here. Here, we are going to produce a Certificate Signing Request (CSR) file that well use later on to create a SSL certificate for push notifications. If youre new to Keychain Access, make sure you dont delete any existing stuff accidentally.
