I talked earlier this week about these and have done further work. The problem I was solving was this: The App will be installed from the App Store but is only for a subset of users. It would be very bad if anyone else was able to use it.

So When it’s first run, it looks for Config info. As it’s never been run and this config info is set internally, it comes up with a screen asking for a few fields to be filled in, but only saves the data if a master password is entered. This information is saved out (password fields are used) and then the App kills the main View, recreates it ie effectively it restarts and upon finding the correct information it works properly. This was done in the View’s ViewDidLoad.

What I found was that the ViewWillAppear only appears to fire the first time and not the second following the View being disposed (UiViews are disposable) and then recreated in the a method in ViewController.
