图片在Swift上从Firebase上通过URL下载时横向加载
问题描述：
我目前正在上传和下载Firebase图片。我将URL作为字符串存储在变量profilePicture中，然后使用URL会话来下载图像。但是，每次照片都会横向加载。但是，当我最初从相机胶卷中选取照片时，会显示正确的方式。任何想法可能发生什么？图片在Swift上从Firebase上通过URL下载时横向加载
上传图片： 当我上传图片，一旦它完全保存，我将URL设置为变量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
}
}
}
下载图片：
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()
}
}
