Firebase 存储到 UIImageView

Question

I am trying to get an image that I have stored inside Firebase Storage inside an UIImageView. I have the URL of the image saved inside Firebase Database for that user, but don't know how to grab it

Answer 1

you need to make an action for it this func opens the Photo carrier

  @IBAction func selecFoto(_ sender: UIButton) {

        let imageController = UIImagePickerController()
            imageController.delegate = self
            imageController.sourceType = UIImagePickerController.SourceType.photoLibrary
//you can also set animate to false 
            self.present(imageController, animated: true, completion: nil)


        }

this func selects the image and you can storage wherever you want

   func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
// here you can preview the image you selected if that's the case 
        imageView.image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
        self.dismiss(animated: true, completion: nil)


    }

Answer 2

import FirebaseStorage

Storage.storage().reference(forURL: yourDownloadedURL).getData(maxSize: 1048576, completion: { (data, error) in

    guard let imageData = data, error == nil else {
        return
    }
    someImageView.image = UIImage(data: imageData)

})

Obviously, handle errors as well as corrupted image data, by perhaps falling back to a default image (just because we have image data in hand does not guarantee it will render a perfect image), and use a maximum file size appropriate to your application.
