Check Login state iOS

[Sebastian-Schuchmann]

Hello,

I have a question regarding the RNIAP.getAvailablePurchases() call. As discussed in issue #747 there is the problem of the flow breaking login prompt and as a proposed solution you can add a restore purchases button.

Is it possible to check the login state of the user to only display the restore purchases button if the user isn't logged in with his apple id? Because if he is already logged in we could just restore purchases in the background without user action required.

Thanks!
