Am I particularly tight today? I am working on an application that should offer obsolete subscriptions to older versions of iOS and automatically renew subscriptions to newer versions of iOS.
I usually check the use of the responsesToSelector test for something suitable in the classes that I want to use, but I donβt see anything in the updated repository, which would allow me to run the test.
So, how should I check if the device supports automatic updating of subscribers? I know that I can check the explicit version number of iOS, but I would prefer not to.
Is there a smarter check I can do?
