Description
NOTE: I am not certain that this is an XF issue, but it feels like it to me. It may also be a general iOS issue. I'd welcome any guidance from the Xamarin team either way.
Description
If a MediaPickerController is displayed after a call to DisplayAlert (or DisplayActionSheet) then orientation changes within the controller cause the UI to go wonky.
Here's an example of things working correctly:
Notice the UI for taking a photo/cancelling looks fine, even though I'd reoriented the camera several times before this shot.
Here's an example of it going awry (after DisplayAlert has been called):
The UI is completely missing (black) and therefore unusable.
Steps to Reproduce
- Download the repro project
- Run it up on iOS
- Select Take Photo
- Rotate the device any number of times in any orientation and observe that it all works as expected
- Cancel the photo
- Select Show an Alert
- Dismiss the alert
- Select Take Photo
- Rotate the device once or twice and observe the UI bug
Expected Behavior
The UI should behave correctly, without being cut off due to an orientation mismatch.
Actual Behavior
The UI does not always respond correctly to the orientation change.
