Force portrait orientation when the device is in landscape (horizontally flipped) for iOS

Question

Firstly, I looked at many other streams in portrait / landscape orientation for iOS.

I have a hybrid application that is built using IBM Worklight (I am mainly focused on the iOS platform, since I already have a solution for Android that works fine). I added the cordova plugin to access device features. My application should be set to portrait on all screens except one. On one screen (view) I need to maintain a landscape and portrait. However, when I switch to another screen, I need to return only to the portrait, but in my many attempts to stay in the landscape.

I use the techniques supportedInterfaceOrientationsand shouldAutorotateto lock and unlock and switch between support only portrait or landscape and portrait.

Note. My application has only one view controller that contains a webview, so I cannot use solutions to reject and present a modal controller.

I also looked at other topics that mention rotation of power using conversion in iOS, but that doesn't work either. Is there a documented way to set iPhone orientation?

(My app supports iOS7 and above) The only thing that worked for me was

[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];

and

objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationPortrait );

However, Apple will reject my application if I use it due to a private api.

Is there any other way to force portrait orientation when the device is rotated to landscape?
