Hey I am new to Xcode and need of assistance in uploading my profile image from firebase database to my user profile. I have receive no errors so far but the image is not appearing when my user logs in, the image is already stored in firebase but when I attach the UIImageView to the user profile the image shows up blank do anyone have a solution to fix this code to make my image appear on the user profile once they log in it should be automatic?

               typealias blockCompletedWith = (Bool, String) -> Void


               //path: folder name if any followed by name of image
  func uploadImageToFirebaseStorage(data: Data, path: String, blockCompletedWith: @escaping blockCompletedWith) {
                     let metadata = StorageMetadata()
                      metadata.contentType = "profileImage.jpg"

                    let store = Storage.storage()
                    let storeRef = store.reference().child(path)
                    let _ = storeRef.putData(data, metadata: metadata) { (metadata, error) in
                       guard let _ = metadata else {
                       print("error occured: \(error.debugDescription)")
                            blockCompletedWith(false, "")
                                    return
                                                  }

                storeRef.downloadURL(completion: { (url, error) in
                     if let urlText = url?.absoluteString {
                     blockCompletedWith(true, urlText)
                                                      }
                                             else {
                                blockCompletedWith(false, "")
                                                      }
                                                  })
                                              }
                                          }


               if let profileImageUrl = dictionary?["gs://tunnel-vision-d6825.appspot.com"] as? String {
                  let url = URL(string: profileImageUrl)
                       URLSession.shared.dataTask(with: url!) { (data, response, error) in
                               if let error = error{
                               print("Error : \(error)")
                    return
                                }
                                    DispatchQueue.main.async {
                                    self.ProfileImage.image = UIImage(data: data!)
                                            }
                    }.resume()

                        }

推荐答案

使用Firebase存储保存图像并将图像链接放入数据库中.

Use firebase storage to save images and put the image link into your database.

typealias blockCompletedWith = (Bool, String) -> Void

func uploadProfileImage(_ image: UIImage) {
        let imageData = image.jpegData(compressionQuality: 1.0)
        let path = "folderName/imagename.jpeg"
        self.uploadImageToFirebaseStorage(data: imageData!, path: path, blockCompletedWith: { (isSuccess, urlStr) in
            Utility.stopActivityIndicator()
            DispatchQueue.main.async {
                if isSuccess {
                    print(urlStr)
                }
                else {
                    print("Error in uploading Image")
                }
            }
        })
    }

-----------uploadImageToFirebaseStorage Method------------

//path: folder name if any followed by name of image
func uploadImageToFirebaseStorage(data: Data, path: String, blockCompletedWith: @escaping blockCompletedWith) {
        let metadata = StorageMetadata()
        metadata.contentType = "image/jpeg"

        let store = Storage.storage()
        let storeRef = store.reference().child(path)
        let _ = storeRef.putData(data, metadata: metadata) { (metadata, error) in

            storeRef.downloadURL(completion: { (url, error) in
                if let urlText = url?.absoluteString {
