Question

Scenario

An app that captures an image from Front camera automatically after 3 sec countdown.
Everything is working as expected.

Code

//in viewDidLoad

 if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
    imagePicker = [[UIImagePickerController alloc] init];
        self.imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;
self.imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
self.imagePicker.delegate = self;
self.imagePicker.showsCameraControls = NO;
[self.imagePicker.view setFrame:kAppFrame];
[self.view addSubview:self.imagePicker.view];
[self.view bringSubviewToFront:self.imagePicker.view];
}

Problem
I have never told the ipad to use its rear device Still in certain cases the rear camera starts.

Steps to reproduce

1. Hold the camera in Landscape orientation
2. Click a photo (Will take you to next screen, pushed in Nav controller)
3. In the next screen tilt the ipad halfway towards face up orientation
4. Comeback to camera screen and you see it using rear camera.

This is a very strange behavior I am not even able to understand its cause.

Answer 1

It looks like I have found the solution.
just moving the entire code to viewWillAppear from viewDidLoad method.

It looked like I was relying a lot on view before it appeared with a certain orientation. Putting the code in viewWillAppear guaranteed me that the view is actually ready with its orientation set. I can now put anything on it.

I know this is not the proper answer but this is what I made out of the scenario. Any modifications/correction are most welcome.
