I have a new iOS app and would like to add facebook integration. One issue that has come up is whether we should stick with Facebook 3.0 or go with Facebook 3.1. It is my understanding that Facebook 3.1 would require iOS 6 (Is this correct?). Honestly, if 20% of people still have iOS 5, it’s probably best for us to stay with that version. Are there any strong opinions on FB 3.0 vs FB 3.1 at this point? Even simple 3 or 3.1 is fine.
thx in advance
There was a post a year or so ago by Matt Gemmell about this, talking about the benefits and downsides to developing for an older version of iOS. His basic argument for latest-only boils down to:
According to Marco Arment’s statistics from Instapaper, nearly 50% of people were using iOS4+ within 50 days of its release, and 98% were using it within 9 months. So, for an existing app, you may need to support older versions for 9 months or so, but for a brand new app, go for the latest and greatest.
