Inserting a Video from the Photo Library in Xcode - ios

Question

I have set up the insertion of the image from the photo library and now I am trying to let the user also select a video from the photo library or camera roll in iOS. I have written the following code:-
extension ViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBAction func didTapOnImageView(sender: UITapGestureRecognizer) {
//call Alert function
self.showAlert()
}
//Show alert to selected the media source type.
private func showAlert() {
var alertStyle = UIAlertController.Style.actionSheet
if (UIDevice.current.userInterfaceIdiom == .pad) {
alertStyle = UIAlertController.Style.alert
}
let alert = UIAlertController(title: "Image Selection", message: "From where you want to pick this image?", preferredStyle: alertStyle)
alert.addAction(UIAlertAction(title: "Camera", style: .default, handler: {(action: UIAlertAction) in
self.getImage(fromSourceType: .camera)
}))
alert.addAction(UIAlertAction(title: "Photo Album", style: .default, handler: {(action: UIAlertAction) in
self.getImage(fromSourceType: .photoLibrary)
}))
alert.addAction(UIAlertAction(title: "Cancel", style: .destructive, handler: nil))
self.present(alert, animated: true, completion: nil)
}
//get image from source type
private func getImage(fromSourceType sourceType: UIImagePickerController.SourceType) {
//Check is source type available
if UIImagePickerController.isSourceTypeAvailable(sourceType) {
let imagePickerController = UIImagePickerController()
imagePickerController.delegate = self
imagePickerController.sourceType = sourceType
imagePickerController.mediaTypes = ["public.image", "public.movie"]
self.present(imagePickerController, animated: true, completion: nil)
}
}
//MARK:- UIImagePickerViewDelegate.
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
self.dismiss(animated: true) { [weak self] in
guard let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage else { return }
//Setting image to your image view
self?.imageView.image = image
self?.imageView.contentMode = .scaleToFill
self?.image20 = self?.imageView.image
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion: nil)
}
}
It works perfectly fine for choosing the image and displaying it, but, now I am able to select the video but, not display it. Could anyone please help on what shall I include in the imagePickerController delegate to obtain the video URL and display it? Thanks for the help! Appreciate it!

Answer 1

You can definitely catch the vide data from your imagePicker, like so:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
picker.dismiss(animated: true) {
if let image = info[.originalImage] as? UIImage,
let data = image.jpegData(compressionQuality: 0.8) {
}
}
if let videoURL = info[.mediaURL] as? URL {
do {
let videoData = try Data(contentsOf: videoURL, options: .mappedIfSafe)
} catch {
print("Error: \(error.localizedDescription)")
}
}
}
Now, after fetching the Data of your selected video file, your next step is to do the research of playing the video data in a view. You can start from this: Implementing video view in the Storyboard
But take heed of the age of that link, it's from 2015, but it should still help you out.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
videoURL = info[UIImagePickerController.InfoKey(rawValue: "UIImagePickerControllerReferenceURL")] as? URL
}
after getting videoURL you can pass it to AVPlayer to play it.
let player = AVPlayer(url: videoURL)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
present(playerViewController, animated: true) {
playerViewController.player!.play()
}
