I tried adding the dependent file Defaultfirstname.lastname@example.org but it crops the app. Any ideas? I read people using Air were having problems as well, but I think adobe did an update. Do we need an update for Director to make full screen apps for the iphone 6 plus? - I did get the regular 6 to work with Defaultemail@example.com.
I managed to get full screen on an iPhone 6 Plus by attaching a dependent file.
Go to Publish Settings -> Files and choose a file that that is a launch image of size 640x1136 pixels. Check box must be set for 'Copy linked and dependant files"
The name of this file is important; Defaultfirstname.lastname@example.org (critical part in bold).
I also used a Prepare Movie script, but not sure if this is really necessary:
if the runmode <> "Author" then
the stageColor = the stageColor -- removes the white screen flash!!!
(the stage).rect = (the desktopRectList) -- Gets the full screen size from the desktop rect!!!
(the stage).drawRect = (the desktopRectList) -- this makes the stage full screen!!!!
