What exactly you are looking for?
Application build with adf mobile running on iOS?
Or an app for iOS to access the forum (which is not available at the moment)?
I am looking for iOS app to acess forums.
Is oracle working on this ?can we expect any app in near future?
do have any suggestions,i am planning to start this app in ADF mobile
Well, I can't comment on what Oracle is up to. From the modernization thread in the Community forum (which is really long to read ) I don't see any plan in the near future to develop one, so if you like to start one, go ahead!
