I am currently finished with making an iOS app and I would like to distribute the app amongst my co-workers using ad-hoc distribution. I have only two months experience with XCode and I am confused about everything about what materials I need to send an app out to my co-workers. I don't want to make an error that I cannot reverse.
What are the essentials I need to bundle in order to distribute an app to other people?
What is a provisioning profile and is it needed to distribute an app?
Is there a way to send people an app using ad-hoc without registering their UDID's?
Lastly, is there a recent tutorial on creating a web link to distribute an app?
Would dropbox be easier?
