旋转IOS模拟器与现实

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

On the simulator this is the result (which looks correct)

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:

Answer 1

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