So I kept on and finally found the answer today here http://community.phonegap.com/nitobi/topics/iphone_5_optimization_requirement-on7f1 and here https://github.com/phonegap/phonegap-start/blob/master/www/config.xml
In a nutshell the issue arose because Apple
, in their never ending pursuit to make things difficult, now requires a "launch screen" image to be included in all apps. As a result, you now have to have, currently, 3 different sized launch screen images with a specific naming procedure on each. The solution that I found via the links above was to place the launch screen images in the root directory and add the following three lines to config.xml
<gap:splash src="Default.png" gap:platform="ios" width="320" height="480" />
<gap:splash src="Default@2x.png" gap:platform="ios" width="640" height="960" />
<gap:splash src="Default-568h@2x.png" gap:platform="ios" width="640" height="1136" />
I'm not sure if the launch screen images are required to be in the root directory or not, but it works for me at the moment. Also, I'm not sure if the images have to begin with "Default", but I do know that the larger two images have to have "@2x" and "-568h@2x" on the end of the file name that's the same name as the smallest image.
For more information on "launch screens" see Apple
's documentation here https://developer.apple.com/library/ios/documentation/userexperience/conceptual/mobilehig/LaunchImages.html
Hope this helps someone.
