I have an App which is rejected which behaves as the Twitter App on the ground that:
10.4 Apps that create alternate desktop/home screen environments or simulate multi-app widget experiences will be rejected
with as description:
We found your app includes a dashboard view which presents multiple
windows at once, and is therefore not in compliance with the App Store
Review Guidelines.The iOS Human Interface Guidelines allow for multiple screens in an
app but access to these screens should always be sequential, never
simultaneous.Please see the attached screenshot/s for more information.
It would be appropriate to modify your app by determining an alternate
way users can accomplish the same task in a single screen or a
sequence of screens.
The screenshot attached is seen below. Can anybody explain what exactly the reason is, looking at the Twitter App. Anybody with a similar experience and a possible solution apart from completely dashing the current interface and putting the ordinary split view controller in?

While I applaud your implementation, it wont make Apple approve you any faster or even at all.
The reason they are rejecting, as they say, is because you can interact with all of those views at once. Standard navigation would push one view over the top of the last using the navigationController and sliding effect. Because Apple views this as a widget type effect where everything is all still running at the same time, you are getting the boot.
One suggestion might be to take a look at how Path and Facebook are implementing the navigation controllers with the slide out effect. You could probably implement something similar where you can just slide the old and the new views on screen. You still need to completely obscure the other views I think to pacify Apple for this rejection. Sorry their ruling wasn’t more favorable. Good luck with your appeal and/or corrections.
