Swift ImagePicker inside NavigationController - ios

Question

So I am inside a navigation controller and would like to present an image picker upon a button press. That works fine, but when I dismiss the picker it throws me back to the root view controller, and not where I want to process the image.
This is my code:
#IBAction func attachPhotoButtonPressed(sender: UIButton) {
imagePicker.sourceType = .SavedPhotosAlbum
presentViewController(imagePicker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
print("Success")
} else{
print("Something went wrong")
}
self.dismissViewControllerAnimated(true, completion: nil)
}
I already looked at these questions, but didn't find a fix. (Not an objective-C guy)

Answer 1

The reason that you're bouncing to the root view controller is because this line
self.dismissViewControllerAnimated(true, completion: nil)
is dismissing the parent view (self), and not the picker view. So assuming that you have a reference to your picker, then you should be calling
picker.dismissViewControllerAnimated(true, completion: nil)

I just had the same problem as you and I'm doing this as an alternative :
// Custom class : see below.
private let imagePicker = ImagePickerViewCustomController()
#IBAction func openPicker(_ sender: Any) {
// Hide the navigation bar when the picker is opened
navigationController!.setNavigationBarHidden(true, animated: false)
// Add it as a subview
addChild(imagePicker)
view.addSubview(imagePicker.view)
}
I have a subclass of UIImagePickerController that hides the status bar.
The content of the scrollView in the picker scroll over the status bar otherwise.
class ImagePickerViewCustomController: UIImagePickerController {
override func viewDidLoad() {
super.viewDidLoad()
UIApplication.shared.isStatusBarHidden = true
}
}
And finally handle delegate methods by dismissing the picker by this way :
extension UIViewController : UIImagePickerControllerDelegate, UINavigationControllerDelegate {
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]){
dismissPicker(picker: picker)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismissPicker(picker: picker)
}
private func dismissPicker(picker : UIImagePickerController){
picker.view!.removeFromSuperview()
picker.removeFromParent()
navigationController?.setNavigationBarHidden(false, animated: false)
UIApplication.shared.isStatusBarHidden = false
}
}
