I currently am uploading and downloading images off of Firebase. I store the URL as a string in the variable profilePicture and then use a URL session to download the image. However, every time the photo loads in sideways. However, when I initially pick the picture form the camera roll, it is shown the correct way. Any ideas of what might be happening?
Uploading Image: When I upload the image, once it is completely saved, I set the URL to the variable profilePicture.
var storageRef : FIRStorageReference = FIRStorageReference()
if let uid = currentUser?.uid {
storageRef = FIRStorage.storage().reference().child("\(uid).png")
}
if let uploadData = UIImagePNGRepresentation(profilePictureImageView.image!) {
let uploadTask = storageRef.put(uploadData, metadata: nil) { snapshot, error in
if let error = error {
print(error)
}
}
// Shows progress bar until saved
uploadTask.observe(.progress) { snapshot in
self.progressBar.observedProgress = snapshot.progress
self.progressBar.isHidden = false;
}
uploadTask.observe(.success) { snapshot in
if let profileImageURL = snapshot.metadata?.downloadURL()?.absoluteString {
self.user?.profilePicture = profileImageURL
self.progressBar.isHidden = true;
self.savedLabel.isHidden = false
}
}
}
Downloading Image:
if let profileImageURL = user?.profilePicture {
if let url = URL(string: profileImageURL) {
URLSession.shared.dataTask(with: url, completionHandler: { (data, response, error) in
if error != nil {
print(error!)
return
}
DispatchQueue.main.async {
self.profilePictureImageView.image = UIImage(data: data!)
self.activityIndicator.stopAnimating()
}
}).resume()
}
}
