Confused about orientation

[Vweston]

I’m confused. I created a new project. Added Swift package to project. Added a cameraView & label to storyboard. Build & run on device (iPad Pro 10.5” - iPadOS 14) in Portrait. Everything looks great. Camera view is correct. Rotate left & image is now displaying 90 degrees right. Rotate device back to portrait & camera image now incorrect there as well.

if I start out in landscape right. Then cameraView is rotated 90 degrees right, but is correct when back in portrait. I can only get it to correctly view in portrait mode no matter what settings I try. See images where the “This is a Label is always correctly displayed above cameraView.

here is my ViewController
//
// ViewController.swift
// BasicCameraManager
//
// Created by Vincent Weston on 1/20/21.
//

import UIKit
import CameraManager

class ViewController: UIViewController {

@IBOutlet weak var cameraView: UIView!

let cameraManager = CameraManager()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    //cameraManager.shouldKeepViewAtOrientationChanges = false
    //cameraManager.shouldRespondToOrientationChanges = false
    
    cameraManager.addPreviewLayerToView(self.cameraView)
}

}

Start in Portrait

rotated

Started in landscapeRight

Rotated back to portrait

any help would be really great.👍

@Vweston Same here. Did you ever find a solution for this?

I have the same issue. Here are the details:

• I'm on Xcode 12.4 (12D4e), the latest as of today.
• Create a new empty template app
• by default in Deployment Info the iOS target is 14.4 and both iPhone and iPad are checked
• pod init and then configure Podfile as per your instructions
• pod install, when it's finished Podfile.lock says that 5.1.3 was installed.
• Add the required privacy entry to info.plist
• in ViewController add let cameraManager = CameraManager()
• and in viewDidLoad() add let cameraManager = CameraManager()

I'm running on two devices. An iPhone X with 14.4.2 and an iPad Mini (5th generation) also on 14.4.2. I get the same results on either device.

1. Start in Portrait. Everything is as expected.
2. Rotate to landscape, either way. Two things happen. The view is rotated 90 deg off from what it should be. And the view is cropped towards the home button.
3. Rotate back to portrait. The view remains cropped and is still 90 deg off.

I notice that the default value in the source for shouldKeepViewAtOrientationChanges is false. So I create a CameraManager subclass and override shouldKeepViewAtOrientationChanges so it returns true. In ViewController I change it to let cameraManager = MyCameraManager()

Then run:

1. Start in Portrait. Everything is as expected.
2. Rotate to landscape. Same result as before. The view crops and is off by 90 deg.
3. Rotate back to portrait. This is correct now. Proper orientation and not cropped.

I haven't found a solution for the orientation issues but viewWillTransition() helped with the cropping.

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)
    cameraManager.addPreviewLayerToView(view)
}

I don't know if that's the best solution for that.

Can you provide any help on the orientation issues?

For my case, I setting like that

cameraManager.shouldKeepViewAtOrientationChanges = false
cameraManager.shouldRespondToOrientationChanges = true

And in where do the update UI when rotation change like viewWillTransition for example (me is updateUIView because I code SwiftUI), call resetOrientation function

DispatchQueue.main.async {
    self.cameraManager.resetOrientation()
}
