Rotation IOS Simulator vs Reality

Question

I am having issues with Storyboards AutoRotation and the iPhone. I've put together a VERY simple project with 3 view controllers which I uploaded to gitHub to demonstrate the issue

I've tested this on the following devices:

IPAD 3
IPHONE 5s
Simulator (iphone / ipad)

Everything seems to work perfectly on the iPad & Simulator (Iphone/Ipad) but when I run it on the 5s it does not rotate correctly.

On the iPhone it will rotate the alert view but not the view controller it appears IPHONE

On the simulator this is the result (which looks correct) enter image description here

Code for sample project can be found at:
https://github.com/jlss/RotationIssues

I am happy and willing to try ANY suggestions anybody has.

Things of Note: (I am using the call objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationLandscapeLeft); ) but as far as I can tell this should be ok.

And lastly i have a simple storyboard with:

`setOrientation:` is private API and can result in removal from the store and undefined behavior. — Léo Natan, Apr 17 '14 at 20:15
@Leo So what would you suggest instead? - Also this app will never go to the store. Furtehrmore MANY answers on here refer to that API — Jeef, Apr 17 '14 at 21:11
Yes, many answers refer to it, but that does not mean it's correct - you have hit a problem due to using it. If you will not be uploading to the appstore, it's less of a problem, but still better to use the proper API. When you want to force a specific orientation, the best method is to use modal presentation. — Léo Natan, Apr 17 '14 at 21:26
Also how is this an illegal API: its right here: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ObjCRuntimeRef/Reference/reference.html#//apple_ref/c/func/objc_msgSend — Jeef, Apr 17 '14 at 22:21
I think you posted a wrong link. See [here](http://stackoverflow.com/questions/15947349/how-to-handle-different-orientations-in-ios/16022631#16022631) for an explanation and example project. — Léo Natan, Apr 17 '14 at 22:31
The problem is not calling `objc_msgSend`, it's about sending a message to `setOrientation`, which is private API. — Léo Natan, Apr 17 '14 at 22:32
This approach also doesn't seem to work well (http://stackoverflow.com/a/15057537/2069812) i guess there is no way to do it in IOS7 — Jeef, Apr 17 '14 at 22:35

Unfortunately you cannot do this if you are using push segues. You have to use modal.
