Generating a download link using firebase - ios

Question

I'm creating an application that lets the user upload an image and then display a direct link in a text field.
Here is the code that is responsible for uploading the image to my bucket and it is triggered when the user's press the upload button.
#IBAction func upload(_ sender: Any) {
let imageContained = viewimage.image
let storage = Storage.storage()
var storageRef = storage.reference()
storageRef = storage.reference(forURL: "bucket link")
var data = NSData()
data = UIImageJPEGRepresentation(imageContained!, 0.8)! as NSData
let dateFormat = DateFormatter()
dateFormat.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let imageName = dateFormat.string(from: NSDate() as Date)
let imagePath = "images/\(imageName).jpg"
let mountainsRef = storageRef.child(imagePath)
let metadata = StorageMetadata()
metadata.contentType = "image/jpeg"
mountainsRef.putData(data as Data, metadata: metadata)
How would I generate a direct link for the user?

Answer 1

Use this below function
func uploadProfilePic(){
var data = NSData()
data = UIImageJPEGRepresentation(ivProfile.image!, 0.8)! as NSData
// set upload path
let filePath = "\(userid)" // path where you wanted to store img in storage
let metaData = FIRStorageMetadata()
metaData.contentType = "image/jpg"
self.storageRef = FIRStorage.storage().reference()
self.storageRef.child(filePath).put(data as Data, metadata: metaData){(metaData,error) in
if let error = error {
print(error.localizedDescription)
return
}else{
//store downloadURL
let downloadURL = metaData!.downloadURL()!.absoluteString
}
}
}

Answer 2

Upload function with completion handler.
func uploadMedia(completion: #escaping (_ url: String?) -> Void) {
let storageRef = FIRStorage.storage().reference().child("myImage.png")
if let uploadData = UIImagePNGRepresentation(self.myImageView.image!) {
storageRef.put(uploadData, metadata: nil) { (metadata, error) in
if error != nil {
print("error")
completion(nil)
} else {
completion((metadata?.downloadURL()?.absoluteString)!))
// your uploaded photo url.
}
}
}
Hope it helps
