How do I add a printed item to Firebase Database? - ios

Question

I am trying to take a printed item and inserting it into my Firebase Database along with the rest of outlets. Thanks!
#objc(imagePickerController:didFinishPickingMediaWithInfo:) func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
myImageView.image = image
} else {
//error
}
self.dismiss(animated: true, completion: nil)
let storageRef = FIRStorage.storage().reference().child("myImage.png")
if let uploadData = UIImagePNGRepresentation(self.myImageView.image!) {
storageRef.put(uploadData, metadata: nil, completion:
{
(metadata, error) in
if error != nil {
print("error")
return
} else {
print((metadata?.downloadURL()?.absoluteString)!)
//i want to take the line above and insert it into the database
}
})
}
}
#IBAction func addPost(_ sender: Any) {
if self.titleText.text != "" && self.authorText.text != "" && self.mainText.text != "" && self.dateText.text != "" {
ref?.child("Posts").childByAutoId()
.setValue(["Title": titleText.text,
"Article": mainText.text,
"Author": authorText.text,
"Date": dateText.text ])
//insert the download URL above
self.performSegue(withIdentifier: "kost", sender: self)
}
}

I see what your problem is now. You are tackling uploading images to firebase in totally the wrong manner. In the event didFinishPickingMediaWithInfo you should not be doing anything with firebase. You should only be setting your UIImageViews image to store the value of the data given from the image picker.
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
self.dismiss(animated: true, completion: nil)
if let editedImage = info[UIImagePickerControllerEditedImage] as? UIImage{
myImageView.image = editedImage
}else{
print("Something went wrong")
}
}
Then in your IBAction, you should upload everything to firebase. Here is a simple function that will upload your image to the database it:
func uploadImage(){
if let fileData = UIImageJPEGRepresentation(myImageView.image!, 0.8){
let storageRef = storage.reference().child("images").child("testImage.jpg")
storageRef.put(fileData, metadata: nil, completion: { (metadata, error) in
if error != nil{
print(error?.localizedDescription ?? "error")
return
}
let downloadURL = metadata?.downloadURL()?.absoluteString
// Write the download URL to your Database
self.ref?.child("images").setValue(downloadURL)
})
}else{
print("error")
}
}
