I have a program that saves a file to the iCloud and this has worked great for iOS7, but now I get this error with iOS8 and cannot seem to find the answer on how to fix it. Anyone else had this problem? Any ideas would be greatly appreciated.
The Error:
CFURLCopyResourcePropertyForKey failed because it was passed this URL which has no scheme: /var/mobile/Containers/Data/Application/ASFHDDE3-B1BB-41D7-A47C-DCC328362W21/Documents/mypictostore.png
The Line of Code Throws Error:
[fileManager setUbiquitous:YES itemAtURL:backupUrl destinationURL:[[ubiq URLByAppendingPathComponent:#"Documents" isDirectory:true] URLByAppendingPathComponent:backupName] error:&theError];
URLS:
destinationURL: file:///private/var/mobile/Library/Mobile%20Documents/ABC23455~MY-Program/
backupUrl: /var/mobile/Containers/Data/Application/ASDFGEEW-B1BB—6FR6-A47C-DCCF21876D36/Documents/mypic.png
Thank you,
Jon
For me this problem was fixed by adding
file://
right before the file path address like this:
var filePath = "file://\(fileURLpath)"
Or maybe you can use NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("mypictostore", ofType: "png")!) instead of using NSURL(string: NSBundle.mainBundle().pathForResource("mypictostore", ofType: "png")!)
Look this link for Objective-c answer: CFURLSetResourcePropertyForKey failed when disable data backup on NSDocumentDirectory
Older Swift version answer:
var str:String = "/var/mobile/Containers/Data/Application/3039975A-5E05-4A4C-8000-55C681A7C35F/Documents/index.html"
var url:URL = URL.init(fileURLWithPath: str)
Swift 4 Answer:
var str:String = "/var/mobile/Containers/Data/Application/3039975A-5E05-4A4C-8000-55C681A7C35F/Documents/index.html"
var url:URL = URL(string: str)!
Depending on what you need to do with the path, you may need to prepend the scheme file://. See more at documentation/foundation/url
If you need the file path, use fileURLWithPath:
let imageURL = URL(fileURLWithPath: imagePath)
it will give you the path as
file:///var/mobile/Containers/Data/Application/7C1D854B-8A2E-4FF0-BD30-0652AEE10B6F/Documents/image_8ZMAM.jpg
If you need the path without the scheme, use string:
let imageURL = URL(string: imagePath)
it will give you the path as
/var/mobile/Containers/Data/Application/7C1D854B-8A2E-4FF0-BD30-0652AEE10B6F/Documents/image_8ZMAM.jpg
look, I find this,The url is The location to write the data into. we should tell the system a file path.
var filePath = "file://(fileURLpath)"
var url:URL = URL.init(fileURLWithPath: fileURLpath)
Data
You can also try this, I think the following code is great as if you are not sure any particular url is correct or not for the CFURLCopyResourcePropertyForKey
if testURL.isFileURL == false {
testURL = URL(fileURLWithPath: testURL.absoluteString)
}
var url = USL(fileUrlWithString: "/private/var/...")

I've got a file path /Users/alexandra/Downloads/folder%20with%20spaces/ and I want to remove the percent encoding and make it a file URL. Using the method stringByRemovingPercentEncoding makes the string null.
The documentation says "A new string with the percent-encoded sequences removed, or nil if the receiver contains an invalid percent-encoding sequence.", but I don't see %20 for a space being wrong?
You didn't show us your non-working code in Objective-C, but this works fine on my machine (in Swift):
if let path = "/Users/alexandra/Downloads/folder%20with%20spaces/".removingPercentEncoding {
let url = URL(fileURLWithPath: path)
print(url) // file:///Users/alexandra/Downloads/folder%20with%20spaces/
}
On the other hand, since you've already wrongly acquired percent encoding in a string pathname, why not just stick file:// in front of it and be done with it?
let path = "/Users/alexandra/Downloads/folder%20with%20spaces/"
if let url = URL(string: "file://" + path) {
print(url)
}
I tried to open a locally stored pdf with xamarin.
example code:
var files = Directory.GetFiles(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData));
var filepath = "file://" + files[0];
if (File.Exists(filepath))
{
await Launcher.OpenAsync(filepath);
}
But the file does not open. The only message I get is (android device):
what do I miss?
EDIT
the variable filepath contains:
file:///data/user/0/com.companyname.scgapp_pdfhandler/files/.config/test.pdf
also tried
file://data/user/0/com.companyname.scgapp_pdfhandler/files/.config/test.pdf
does not help
Figured I would add my comment as an answer for easier visibility in case others run into it in the future.
Pass a OpenFileRequest object instead, if you use a string it has to be the correct uri scheme for it. I suspect the uri scheme you are passing to it isn't something that is understood by the system
I am trying to upload images to Real time Firebase Database by creating two folders using Compressor library and need to display image like messenger with username but i am unable to display image due to url issue
var filePath = mStorageRef!!.child("chat_profile_images")
.child(userId + ".jpg")
//Create another directory for thumbimages ( smaller, compressed images)
var thumbFilePath = mStorageRef!!.child("chat_profile_images")
.child("thumbs")
.child(userId + ".jpg")
filePath.putFile(resultUri)
.addOnCompleteListener{
task: Task<UploadTask.TaskSnapshot> ->
if (task.isSuccessful) {
//Let's get the pic url
var donwloadUrl = task.result?.storage?.downloadUrl.toString()
Log.d(TAG, "Profilepic link: $donwloadUrl")
//Upload Task
var uploadTask: UploadTask = thumbFilePath
.putBytes(thumbByteArray)
uploadTask.addOnCompleteListener{
task: Task<UploadTask.TaskSnapshot> ->
var thumbUrl = task.getResult()?.storage?.downloadUrl.toString()
Log.d(TAG, "Profilepic link: $thumbUrl")
i tried to change downloadUrl
filepath.downloadUrl.toString
thumbFilePath.downloadUrl.toString
but both these values getting "com.google.android.gms.tasks.zzu"
i also tried to change
task.result.sessionurl.downloadUrl.toString
for this one i am getting downloadUrl but not a complete solution for my problem as still i cannot display image i need to get thumbUrl downloadUrl
You have the exact same and very common misunderstanding as in this question, except it's in java. You should follow the documentation here to understand get getDownloadUrl works. As you can see from the linked API documentation, it's not a property getter, it's actually a method that returns a Task<Uri> that tracks the asynchronous fetch of the URL you want, just like the upload task:
filePath.downloadUrl
.addOnSuccessListener { urlTask ->
// download URL is available here
val url = urlTask.result.toString()
}.addOnFailureListener { e ->
// Handle any errors
}
This will only work after the upload is fully complete.
Correct way of getting download link after uploading
here
Just putting out there, I also encounter the same problem,
but both these values getting "com.google.android.gms.tasks.zzu"
but it wasn't the same mistake from the OP
used addOnCompleteListener instead of addOnSuccesslistener
My Error code:
imageRef.downloadUrl.addOnCompleteListener { url ->
val imageURL = url.toString()
println("imageURL: $imageURL , url: $url")
addUserToDatabase(imageURL)
}
I am extremely new to swift so bear with me. I am trying to figure out how to search the PDF document for a particular string. I am assuming I need to use the findString function. I just do not know exactly how the parameters should be implemented. I am using Apple Docs. and couldn't see a description of this.
Thanks!=]
private func loadPDF(){
guard
let url = Bundle.main.url(forResource: pdfTitle, withExtension: "pdf"),
let document = PDFDocument(url:url)
else {fatalError()}
pdfView.document = document
}
func findString(_ string: String,
withOptions options: NSString.CompareOptions = []) -> [PDFSelection]
To get a list of matches you do something like this:
let matches = document.findString("foo", withOptions: .caseInsensitive)
I am new to SWIFT and I just started implementing my first application for OS X. I created a simple project and decided Ill look into different frameworks for using zip/rar files. I started with ZipArchive as recommended but couldn't make it work in my project - didn't even compile (probably something wrong with my setup), I had similar experience with Objective-Zip and SSZipArchive. Finally I stumbled on the framework zip zap which attached to my project perfectly.
I looked into the examples:
ZZArchive* oldArchive = [ZZArchive archiveWithURL:[NSURL fileURLWithPath:#"/tmp/old.zip"] error:nil];
ZZArchiveEntry* firstArchiveEntry = oldArchive.entries[0];
NSLog(#"The first entry's uncompressed size is %lu bytes.", (unsigned long)firstArchiveEntry.uncompressedSize);
NSLog(#"The first entry's data is: %#.", [firstArchiveEntry newDataWithError:nil]);
but I couldn't make it work with SWIFT. The problem I faced is that I couldn't create a NSURL that worked with the ZZArchive.
let zip:ZZArchive = ZZArchive(NSURL(fileURLWithPath:"/Users/../tesData/test.zip"))
led to
fatal error: unexpectedly found nil while unwrapping an Optional value
and everything else I tried either didn't compile with a unwrapping error or compiled but on execution led to this error.
Can someone please either help me solve my unzipping problem, or lead me to a solution of how to zip/unzip/read zip/rar/cbr files with swift.
This should fix it
var path = NSURL.fileURLWithPath("/Users/../tesData/test.zip")
var archive: ZZArchive = ZZArchive(URL:(fileURLWithPath:path!), error: &err)
Here is an implementation of zzzip in swift
//Declare
var err: NSError? = NSError()
var path = NSURL.fileURLWithPath("/PathToZipFile/file.zip")
var URL3 = NSURL.fileURLWithPath("/pathanywhereinsystemtosaveunzipedfolder/")
var URL2 = NSURL.fileURLWithPath("/PathToUnzippedFile/file.xxx")
var fileManager = NSFileManager.defaultManager() //1
let archive: ZZArchive = ZZArchive(URL:(fileURLWithPath:path!), error: &err)//2-3
//Create Folder
fileManager.createDirectoryAtURL(URL3!, withIntermediateDirectories: true, attributes: nil, error: &err)
//Write First entry of archive to file
var k = archive.entries[0].newDataWithError(nil)
k.writeToURL(URL2!, atomically: false)
This works for small text files and images. it does have its limitations due to no errorchecking and only writing the first archive entery to a file. If any paths are wrong you will end with errors as soon as you try and compile.
