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 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?
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)")
}
})

What I have tried so far:
Checked firebase storage rules.
When I paste the path https:/firebasestorage.googleapis.com/v0/b/trainer8cb52.appspot.com/o/WORKOUTDATA%2FUSERS%2F1K7WV1alYIeWPAsFC6YMoJKPFSj1%2FWHITEBOARDWORKOUTS%2F5%2FWORKOUTPICTURES%2FPicture1.jpg?alt=media&token=785ab8c7-1e08-4ad3-a542-c9e6313eb547 in chrome browser window, the expected image opens.
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 try to get metadata of files from Firebase Storage, in particular date of create (because I want to compare date of local file and date of Cloud file and change file, if needed). I use getMetadata { (metadata, error) in ...} method, but I don't get result in my completion. Control doesn't go to completion! My code is below
let metadataURL = Storage.storage().reference().child("tutorials/how_to/use_masking/cover.jpg")
metadataURL.getMetadata { (metadata, error) in
if let error = error {
print(error)
} else {
if let data = metadata {
let dict = data.dictionaryRepresentation()
print(dict)
}
}
}
And I want to say now, that image is really in this path, because I get this image with getData(...) method in the next step.
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 creating an iOS application through which users can print the files on their device. From my application, I can access the files on the device though the DocumentPicker provided by other apps such as iCloud Drive, Dropbox, etc.
Now, I want to add a functionality where user can share the file with my application through an other application. I created an Action Extension for that.
For example, if I select an Image in the Photos application and select Share I get my extension in the Share sheet and when I select it, I also get the URL of the file. Next, I am creating a zip file of this file to send it to my server. But the issue is, the zip file is always empty. The code I am using is as below:
In Action Extension's viewDidLoad()
if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage as String) {
itemProvider.loadItemForTypeIdentifier(kUTTypeImage as String, options: nil,
completionHandler: { (image, error) in
NSOperationQueue.mainQueue().addOperationWithBlock {
print("Image: \(image.debugDescription)")
//Image: Optional(file:///Users/guestUser/Library/Developer/CoreSimulator/Devices/00B81632-041E-47B1-BACD-2F15F114AA2D/data/Media/DCIM/100APPLE/IMG_0004.JPG)
print("Image class: \(image.dynamicType)")
//Image class: Optional<NSSecureCoding>
self.filePaths.append(image.debugDescription)
let zipPath = self.createZip(filePaths)
print("Zip: \(zipPath)")
}
})
}
And my createZip function is as follows:
func createZipWithFiles(filePaths: [AnyObject]) -> String {
let zipPath = createZipPath() //Creates an unique zip file name
let success = SSZipArchive.createZipFileAtPath(zipPath, withFilesAtPaths: filePaths)
if success {
return zipPath
}
else {
return "zip prepation failed"
}
}
Is there a way that I can create a zip of the shared files?
Your primary issue is that you are blindly adding image.debugDescription to an array that is expecting a file path. The output of image.debugDescription isn't at all a valid file path. You need to use a proper function on the image to obtain the actual file path.
But image is declared to have a type of NSSecureCoding. Based on the output of image.debugDescription, it seems that image is really of type NSURL. So you need to convert image to an NSURL using a line like:
if let photoURL = image as? NSURL {
}
Once you have the NSURL, you can use the path property to get the actual needed path.
So your code becomes:
if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage as String) {
itemProvider.loadItemForTypeIdentifier(kUTTypeImage as String, options: nil,
completionHandler: { (image, error) in
if let photoURL = image as? NSURL {
NSOperationQueue.mainQueue().addOperationWithBlock {
let photoPath = photoURL.path
print("photoPath: \(photoPath)")
self.filePaths.append(photoPath)
let zipPath = self.createZip(filePaths)
print("Zip: \(zipPath)")
}
}
})
}
Hint: Never use debugDescription for anything other than a print statement. Its output is just some string that could contain just about any information and that output can change from one iOS version to the next.
