Rxswift: How to observe orientation change with RxSwift

[jibeex]

Hi,

Is there an Rx property on which we can subscribe for orientation change device ?

[sergdort]

Hm, I'm not sure whether there are any NSNotification
But you can observe viewWillTransitionToSize kinda like this:

rx_sentMessage(#selector(UIViewController.viewWillTransitionToSize(_:withTransitionCoordinator:)))
         .subscribeNext { (params) in
            //Do something here on size class change
         }
         .addDisposableTo(disposeBag)

Looks a little bit complex. It seems better to

use view.rx_observe(CGRect.self, "frame")

[Succete]

maybe observe UIDeviceOrientationDidChange notification.

[acecilia]

NSNotificationCenter.defaultCenter().rx_notification(UIDeviceOrientationDidChangeNotification).subscribeNext {}

Assuming this is resolved :)

The solution is to find a better alternative.

 NotificationCenter.default.rx.notification(UIDevice.orientationDidChangeNotification)
            .observeOn(MainScheduler.instance)
            .subscribe(onNext: { data in
                print("data \(data)")
            })
        .disposed(by: disposeBag)
