I am using iOS SDK 1.3.13 with the iOS 8.1 simulator. When my app calls the linkFromController method, it presents the appropriate dialog to connect to Dropbox. As soon as the connection dialog appears, however, the app attempts to connect to a large number of external web addresses (detected via use of Little Snitch on my development Mac):
cf.dropboxstatic.com
dropbox.com
www.googleapis.com
marketing.dropbox.com
id.google.com
www-googletagmanager.l.google.com
code.google.com
connect.facebook.net
sjs.bizographics.com
stats.g.doubleclick.net
platform.twitter.com
s.adroll.com
www.bizographics.com
t.co
d.adroll.com
www.v.dropbox.com
analytics.twitter.com
adservers-users-4-751266504.us-east-1.elb.amazonaws.com
googleads4.g.doubleclick.net
secure.anycast.adnxs.com
google-analytics.com
bat.bing.com
graph.facebook.com
The app itself never makes use of these other (non-Dropbox) services. Why is the Dropbox SDK connecting to facebook, twitter, and various ad servers, assuming that is what is going on?
