[Bug] [iOS] CameraView changes it's size in horizontal orientation #2001

Closed Nikclim closed 10 months ago

Nikclim commented 10 months ago

Description

If I make photo and hold device vertical CameraView works correctly. But if I make photo and hold device horizontal (when device camera looks down) or with some angle, CameraView changes it's own size after opening page where I use it. Besides, ImageView, which I use for showing preview, also changes it's own size, if I made photo, while device was held horizontal.

If I lock screen orientation using device button, CameraView works correctly. But locking orientation using Supported device orientations in info.plist and overriding GetSupportedInterfaceOrientations doesn't work.

I used to use Device.Info.ScaledScreenSize.Height for setting CameraView height. It caused resizing. Using App.Instance.MainPage.Height resolves issue.
