Rotation of uiscreen SWIFT

Question

I have disabled all orientation modes except the portrait one in my info.plist file because I don't want the app to rotate. However I want one view controller to be only in landscape mode. Can I change the orientation programmatically in the class of the view controller? Or can i disable autorotation in info.plist but enable portrait and landscape mode?

Also I know that I can check the orientation the phone is hold by UIDevice.currentDevice().orientation.isLandscape

But is there a method that gets executed when you hold your phone differently?

See in UIViewController.h the shouldAutorotate and supportedInterfaceOrientations methods.

I tried to use the supportedInterfaceOrientations a method but the view did not rotate. Also the should autorotate method does not work when only Portrait is allowed. Or are they only working together? – Lenny1357 May 18 '16 at 15:18

If you want to do present just one VC in an orientation different from the most of the others in the info.plist you must set a set of values that comprehends all the supported orientation.
To avoid the possibility of a VC to rotate in a particular orientation you should override

- shouldAutorotate
- supportedInterfaceOrintation
- preferredInterfaceOrientationForPresentation

Is it possible to make an extension of UIViewController and override the method separately for this one view controller? – Lenny1357 May 18 '16 at 15:46
If you read the link I've posted, in an answer a user explain how to do that just by overriding a method in the app delegate – Andrea May 18 '16 at 15:48

But then I can't programmatically switch to landscape when the app is in Portrait – Lenny1357 May 19 '16 at 19:01
Correct, if you want to manage multiple orientation, as I already said, you must select all the orientation you want to support in general and for fine grained control use the methods I wrote above. – Andrea May 19 '16 at 20:04

You can't, but you can lock the rotation of the view controller that contains it, by using the methods above. – Andrea May 20 '16 at 19:26
Unfortunately the video will also rotate when I do that. – Lenny1357 May 20 '16 at 19:31
