Save two different images at the same time on firebase - ios

Question

I try to save two different images at the same time at one storage location
This is my function to save the information
var text: String = ""
var addedByUser: String?
var userImage: UIImage?
var jobImage: UIImage!
var downloadURL: String?
var userDownloadURL: String?
let ref: DatabaseReference!
init(text: String? = nil, jobImage: UIImage? = nil, addedByUser: String? = nil, userImage: UIImage? = nil) {
self.text = text!
self.jobImage = jobImage
self.addedByUser = addedByUser
self.userImage = userImage
ref = Database.database().reference().child("jobs").childByAutoId()
}
init(snapshot: DataSnapshot){
ref = snapshot.ref
if let value = snapshot.value as? [String : Any] {
text = value["text"] as! String
addedByUser = value["addedByUser"] as? String
downloadURL = value["imageDownloadURL"] as? String
userDownloadURL = value["imageUserDownloadURL"] as? String
}
}
func save() {
let newPostKey = ref.key
// save jobImage
if let imageData = jobImage.jpegData(compressionQuality: 0.5) {
let storage = Storage.storage().reference().child("jobImages/\(newPostKey)")
storage.putData(imageData).observe(.success, handler: { (snapshot) in
self.downloadURL = snapshot.metadata?.downloadURL()?.absoluteString
let postDictionary = [
"imageDownloadURL" : self.downloadURL!,
"imageUserDownloadURL" : self.userDownloadURL!,
"text" : self.text,
"addedByUser" : self.addedByUser!
] as [String : Any]
self.ref.setValue(postDictionary)
})
}
}
I tried following code
if let imageData = jobImage.jpegData(compressionQuality: 0.5), ((userImage?.jpegData(compressionQuality: 0.5)) != nil) {
But it's not working as then nothing get's saved in the database...
Do you have any ideas how I can solve it?

I believe the question is how do I upload an image to two different locations. It's unclear why there's an observe function so this answer ignores that as it may not be needed.
Starting with your code, your save function will look like this
func save() {
self.uploadImageTask(imageName: "my_image.png", toLocation: "jobImage")
self.uploadImageTask(imageName: "my_image.png", toLocation: "anotherLocation")
}
and then the upload function
func uploadImageTask(imageName: String, toLocation: String) {
let theImage = UIImage(named: imageName) //set up your image here
let data = UIImagePNGRepresentation(theImage)! //we're doing a PNG
let storage = Storage.storage()
let storageRef = storage.reference()
let locationRef = storageRef.child("images").child(toLocation)
let imageLocationRef = locationRef.child(imageName)
// Upload the file to the path "images/location/imageName"
let uploadTask = locationRef.putData(data, metadata: nil) { (metadata, error) in
guard let metadata = metadata else {
print("error while uploading")
return
}
let size = metadata.size // Metadata contains file metadata such as size, content-type.
print(size)
locationRef.downloadURL { (url, error) in
guard let downloadURL = url else {
print("an error occured after uploading and then downloading")
return
}
let x = downloadURL.absoluteString
print(x) //or build a dict and save to Firebase
}
}
}
the result is an image stored at
/images/jobImage/my_image.png
/images/anotherLocation/my_image.png
and it will also print the path to each image, which could be stored in Firebase.
