If you want to post your app to the app store you will need to use a Production Provisioning Profile, therefore all notifications sent with APNS Developer Certificate will not arrive to your app signed with a Production Provisioning Profile.
Why not use only a production APNS certificate? Well you can do this but…
- In order to test you will need to build your app with a Production Ad Hoc Provisioning Profile, this is a lot of extra work at compiling
- Using a production cert in development, and therefore using an ad-hoc build, you cannot run with the debugger. Makes troubleshooting very painful.
- Test notifications makes everything goes to production so you have to be extra careful
