I am showing the camera in a popover (on an iPad - the iPad app is locked to Lanscape Left) and the preview is in Portrait and the wrong scale. The code is below - I have worked out the rotation and added it, but the preview size is the too thin now.
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.videoQuality = UIImagePickerControllerQualityTypeMedium;
imagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
CGAffineTransform transformRotation = CGAffineTransformMakeRotation(270 * M_PI/180);
imagePicker.cameraViewTransform = transformRotation;
}
else
{
NSLog(@"Camera not available. Using photo library");
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
imagePicker.delegate = self;
_photoPopover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[_photoPopover presentPopoverFromRect:view.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
