I am struggling with uploading videos from iOS photo album to Azure blob storage. I am using AZSClient.
uploading images is straight forward, ie. I get the image 'Data' from PHAsset and then upload it to azure storage using AZSCloudBlockBlob.uploadFromData method
Can anyone guide me on how to upload a video to azure blob preferably in swift
There was a similar thread for this they used the bellow code, and they used the IOS library found here:
//Upload to Azure Blob Storage with help of SAS
func uploadBlobSAS(container: String, sas: String, blockname: String, fromfile: String ){
// If using a SAS token, fill it in here. If using Shared Key access, comment out the following line.
var containerURL = "https://yourblobstorage.blob.core.windows.net/\(container)\(sas)" //here we have to append sas string: + sas
print("containerURL with SAS: \(containerURL) ")
var container : AZSCloudBlobContainer
var error: NSError?
container = AZSCloudBlobContainer(url: NSURL(string: containerURL)! as URL, error: &error)
if ((error) != nil) {
print("Error in creating blob container object. Error code = %ld, error domain = %#, error userinfo = %#", error!.code, error!.domain, error!.userInfo);
}
else {
let blob = container.blockBlobReference(fromName: blockname)
blob.uploadFromFile(withPath: fromfile, completionHandler: {(NSError) -> Void in
NSLog("Ok, uploaded !")
})
}
}
I found the answer in this thread
let manager = PHImageManager.default()
manager.requestAVAsset(forVideo: asset, options: nil, resultHandler: { (avasset, audio, info) in
if let avassetURL = avasset as? AVURLAsset {
guard let video = try? Data(contentsOf: avassetURL.url) else {
return
}
videoData = video
}
})
once you get the Data object then you can use AZSCloudBlockBlob.uploadFromData to upload it to azure storage

I am trying to save an image to the user's photo library using PHPhotoLibrary and set the image file name at the time of saving suing the code below.
This is working the first time, but if I then try to save the same image again with a different file name, it saves with the same file name as before.
Is there something I need to add to let the system know to save a new version of the image with a new file name?
Thank you
PHPhotoLibrary.shared().performChanges ({
let assetType:PHAssetResourceType = .photo
let request:PHAssetCreationRequest = .forAsset()
let createOptions:PHAssetResourceCreationOptions = PHAssetResourceCreationOptions()
createOptions.originalFilename = "\(fileName)"
request.addResource(with: assetType, data: image.jpegData(compressionQuality: 1)!, options: createOptions)
}, completionHandler: { success, error in
if success == true && error == nil {
print("Success saving image")
} else {
print("Error saving image: \(error!.localizedDescription)")
}
})

The code to upload image and save download URL: (Which works fine, because I can see images uploaded to storage and their respective download URLs stored to real-time database.)
let storageRef = Storage.storage().reference()
//Let's upload all workout pictures
let uploadPicsRef =
storageRef.child("WORKOUTDATA/USERS/"+self.UID!).child("WHITEBOARDWORKOUTS")
let uploadNumberRef = uploadPicsRef.child("\(String(describing: workoutNum))")
let workoutPicturesRef = uploadNumberRef.child("WORKOUTPICTURES")
let workoutPicURLRef = workoutRef.child("WORKOUTPICTURESURL")
var count = 0
var picNumber = 0
//workoutPictures list/array contains images selected from iPhone Gallery, using
//UIImagePickerController
for workoutPic in self.workoutPictures
{
let workoutPicData = workoutPic.jpegData(compressionQuality: 1.0)!
count = count + 1
let pictureName = "Picture\(count).jpg"
// Upload the file to the path in pictureRef
let pictureRef = workoutPicturesRef.child("\(pictureName)")
let metaData = StorageMetadata()
metaData.contentType = "image/jpg"
pictureRef.putData(workoutPicData, metadata: metaData) { (metadata, error) in
if error != nil {
print("Error while uploading image")
}
else
{
pictureRef.downloadURL { (url, err) in
picNumber = picNumber + 1
workoutPicURLRef.child("Picture\(picNumber)").setValue(url?.absoluteString)
}
}
}
}
The code to download image:
let myGroup = DispatchGroup()
let workoutPicUrls = snapshot.childSnapshot(forPath: "WORKOUTPICTURESURL")
for url in workoutPicUrls.children
{
myGroup.enter()
let snap = url as! DataSnapshot
let link = snap.value as? String
let storageRef = Storage.storage().reference()
let pictureRef = storageRef.root().child(link!)
DispatchQueue.main.async {
pictureRef.getData(maxSize: 1*2000000*2000000) { (data, err) in
if (err != nil) {
print(err!)
print(err!.localizedDescription)
} else {
let pic = UIImage(data: data!)
workoutPicsArray.append(pic!)
myGroup.leave()
}
}
}
}

Set the maxSize to a ridiculously high number 1*2000000*2000000.
Thank you!
Is it possible that you are storing the full https URL in the database and are trying to create a reference by adding the full https url as a child to the storage reference?
I think you should try to either store just the path and name in your database or you change your download code to use the https URL.
// Create a reference from an HTTPS URL
// Note that in the URL, characters are URL escaped!
let httpsReference = storage.reference(forURL: "https://firebasestorage.googleapis.com/b/bucket/o/images%20stars.jpg")
httpsReference.getData(maxSize: ...
Also you're running your getData method inside DispatchQueue.main.async. getData has itself a completion handler and might take some time, when you run that inside of DispatchQueue.main.async it will block your code until the download is done. Only put code that update the UI inside DispatchQueue.main.async. In your case as soon as you do something with your workoutPicsArray or the UIImage to update your view.
Have a look here to see if you can figure out how you are actually trying to get the data. It might be helpful to put a print() after each line to see what you are creating and using at what point.
Download Files on iOS
I’m using AWS to upload videos from my App.
I can able to upload up to 5 GB single video without any problem with AWSS3TransferUtilityTask.
My requirement is I want to upload more than 5 gb video file.(e.g 7GB, 10GB , 13GB)
I’ve tried with AWSS3TransferUtilityMultiPartUploadTask to upload more then 5 gb files. After completing more then 60% of upload I'm getting an error (NSURLErrorDomain error -1001).
// Completion Handler
let completionHandler : AWSS3TransferUtilityMultiPartUploadCompletionHandlerBlock? =
{ (task, error) -> Void in
if ((error) != nil)
{
print("------------------>",error?.localizedDescription ?? "")
}
else
{
print("File uploaded successfully")
}
}
//Expression
let expression = AWSS3TransferUtilityMultiPartUploadExpression()
expression.progressBlock = progress
//Content Type
let contentType = "video/mp4"
let transferUtility = AWSS3TransferUtility.default()
transferUtility.uploadUsingMultiPart(fileURL: uploadingFileURL, bucket: bucket, key: path + filename, contentType: contentType, expression: expression, completionHandler: completionHandler)
}
else {
print(" session out----->",jsonData)
}
Thanks in advance.
I'm searching for an useful Swift 3 Azure Blob Storage example which I could use to upload some data(image, video). For now, I can insert records into my Mobile Service database and there I generate a SAS and I get it back to my iOS application. Now I need to know how to upload to Azure Blob Storage with help of that SAS. I successfully implemented the same for Android and it works, but somehow I have troubles to find any useful information for "SWIFT" and how to use the "SAS"!
Any code examples how to upload with SAS in Swift are much appreciated.
Regards,
Adam
For those who have the same problem as I had: This is a working example in Xcode 8 and Swift 3. You have to include the "Azure Storage Client Library" into your project.
//Upload to Azure Blob Storage with help of SAS
func uploadBlobSAS(container: String, sas: String, blockname: String, fromfile: String ){
// If using a SAS token, fill it in here. If using Shared Key access, comment out the following line.
var containerURL = "https://yourblobstorage.blob.core.windows.net/\(container)\(sas)" //here we have to append sas string: + sas
print("containerURL with SAS: \(containerURL) ")
var container : AZSCloudBlobContainer
var error: NSError?
container = AZSCloudBlobContainer(url: NSURL(string: containerURL)! as URL, error: &error)
if ((error) != nil) {
print("Error in creating blob container object. Error code = %ld, error domain = %#, error userinfo = %#", error!.code, error!.domain, error!.userInfo);
}
else {
let blob = container.blockBlobReference(fromName: blockname)
blob.uploadFromFile(withPath: fromfile, completionHandler: {(NSError) -> Void in
NSLog("Ok, uploaded !")
})
}
}
I'm using Firebase Storage to store images in FB, I'm saving download URL in Realtime DB and to retrieve some photos from the storage, I'm using this code:
let storage = FIRStorage.storage()
imageRefInDB.observeEventType(.Value, withBlock: { (snapshot) in
// Get download URL from snapshot
let downloadURL = snapshot.value as! String
// Create a storage reference from the URL
let storageRef = storage.referenceForURL(downloadURL)
storageRef.dataWithMaxSize(1 * 1024 * 1024) { (data, error) -> Void in
if (error != nil) {
print(error.debugDescription)
} else {
let downloadedImage = UIImage(data: data!)
}
}
})
My problem is I wanna use some of my photo that are inside another Firebase project. For example, the download URLs will be:
https://firebasestorage.googleapis.com/v0/b/PROJECT1.appspot.com/o/someMedia&token
When in my current project, the bucket is different like :
https://firebasestorage.googleapis.com/v0/b/PROJECT2.appspot.com/o/someMedia&Token
When I try to using the PROJECT1 files in my current PROJECT2, I'm getting the following error:
reason: 'Provided bucket: PROJECT1.appspot.com does not match bucket specified in FIRApp configuration: PROJECT2.appspot.com
Is there a way to enable downloading theses files from other projects like a setting in Firebase without retrieving them with regular URL downloads?
Thanks for your help!
I tried that once and it lead to an unhappy time. In my case I had two different buckets for my images, so I had to find an alternate solution.
If you have only a single bucket, you can try configuring that bucket in your FIRApp:
let firOptions = FIROptions(googleAppID: googleAppID, bundleID: bundleID, GCMSenderID: GCMSenderID, APIKey: nil, clientID: nil, trackingID: nil, androidClientID: nil, databaseURL: databaseURL, storageBucket: storageBucket, deepLinkURLScheme: nil)
FIRApp.configureWithName("anotherClient", options: options)
let app = FIRApp(named: "anotherClient")
let storageRef = FIRStorage.storage(app: app!).reference()
Taken from this answer, so you may need to modify it to suit your needs
With that app, you can then use the Firebase Storage API as you're already doing to download the image data.
If you have multiple buckets (as I had), you either have to configure multiple apps or (as I did) handle downloading the image from the downloadURL yourself (without using the Firebase Storage API):
dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0)) {
let data = NSData(contentsOfURL: downloadURL) //make sure your image in this url does exist, otherwise unwrap in a if let check
dispatch_async(dispatch_get_main_queue(), {
let downloadedImage = UIImage(data: data!)
});
}
