I would like to share a file (gpx) via the Gmail client app on the iPhone.
The problem is that the created mail does not contain the "shared" .gpx file.
Code for creating the share request:
let itemProver = GPXItemProvider(itemInformation) // Subclass of UIActivityItemProvider
let shareController = UIActivityViewController(activityItems:[itemProver], applicationActivities: nil)
present(controller: shareController)
The code itself does work nevertheless because if I try to export the gpx file into the default mail client on the device, everything works fine.
Do I miss something which requires the GMail app to contain the file as the attachement?
This topic covers a similar problem. A third-party library is used there though, which is not an option in my case:
Send an iphone attachment through email programmatically
Thank you.
You can write the GPX file to a temporary directory and share the URL instead of your custom item.
let data = ...
let url = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent("test.gpx")
try data.write(to: url)
let shareController = UIActivityViewController(activityItems:[url], applicationActivities: nil)

My app uses remote notifications with a NotificationService Extension in which I edit the notification before displaying it.
I would like to let the user upload a custom sound file which should be played instead of the default sound. For this I use an shared AppGroup, which the app and the extension have access to.
The uploaded sound files are stored in the "Library/Sounds" directory as follows (my code for testing, without much error handling):
.....
let containerURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.com.xxx.xxx")
let soundsURL = containerURL!.appendingPathComponent("Library/Sounds/", isDirectory: true)
if !FileManager.default.fileExists(atPath: soundsURL.path) {
try! FileManager.default.createDirectory(atPath: soundsURL.path, withIntermediateDirectories: true)
}
if FileManager.default.fileExists(atPath: soundsURL.path) {
do {
try FileManager.default.copyItem(at: sourceURL, to: soundsURL.appendingPathComponent(sourceURL.lastPathComponent))
} catch {
// Exception
}
}
In the Notification Extension I change the sound of the notification to the name of the uploaded file:
bestAttemptContent.sound = UNNotificationSound(named: UNNotificationSoundName(rawValue: "test.wav"))
This is working fine as long as the iPhone is not locked. But if the iPhone is locked, there is no vibration and no sound is played (also no default sound). But I don't know why - according to apples documentation UNNotificationSound looks in "Library/Sounds" of the app shared group container directories. If I store the file directly in the main bundle, it works.
Does anyone have any idea what could be causing this?
Ok, now i figured out what the problem is.
My files were created with "NSFileProtectionComplete" data protection by default.
"NSFileProtectionComplete — The file is only accessible while the device is unlocked."
After changing the data protection of my sound files to "NSFileProtectionNone", it finally works!
I am very new to this IOS swift programming. So need some suggestion and help. I am creating an app in which I have to show different file coming from the server. Below is the kind of link from which my file data is coming.
http://demo.xxxx.com/dctm-rest/repositories/iol_ref2/objects/0900a18480383d14/content-media?format=pdf&modifier=&page=0
This above link is for pdf or it can be of any type (txt, doc, img etc) so I have tried so many things but I was unable to get a result.
Solutions What I have tried:-
With basic auth, I am requesting URL and getting contents from the file, so I was getting data from server and printing on console but when I tried to copy that contents to one file it says unable to copy says no such file or folder exist but I have properly defined the path location. Below is my code link which I have asked earlier.

Someone suggested using Alamofire lib that also I have used but no luck. Below is the code which I have referred.
Alamofire: finished with error - code: -1001
So let me know what I am doing is correct or not or is there any new method or way I can try. I have tried web view too. So please help me with this.
Thanks in advance
I use code like this to download a file and store it locally.
let destination: DownloadRequest.DownloadFileDestination = { _, _ in
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let fileURL = documentsURL.appendingPathComponent(documentFilename)
return (fileURL, [.removePreviousFile])
}
Alamofire.download(url, to: destination).response { [unowned self] response in
// check download and call completion handler
}
What code did you use to download the file?
Is it possible to share a video on Instagram without saving it to the user's Camera Roll?
this is what i tried so far:
let instagramURL = URL(string: "instagram://app")!
if (UIApplication.shared.canOpenURL(instagramURL)) {
self.documentController = UIDocumentInteractionController(url: videoURL)
self.documentController.delegate = self
self.documentController.uti = "com.instagram.exlusivegram"
self.documentController.presentOpenInMenu(from: self.view.frame, in: self.view, animated: true)
} else {
print(" Instagram isn't installed ")
}
videoURL is the URL of the video i saves in the Documents folder.
if I save the URL with Instagram.igo at the end, then when i choose Instagram to share it opens like this:
if I save the video with .mov at the end, it seems that Instagram share opens with a photo (like video thumbnail) and not a video.
What exactly you did wrong is difficult to determine, but I'll try to address where you might have been wrong.
First of all make sure that the videoURL is defined locally. When I wrote an app posting to Instagram, I first defined the path with file manager, like:
let tempDirectory = FileManager().temporaryDirectory
var postingPath = tempDirectory.appendingPathComponent("postingVideo")
postingPath = postingPath.appendingPathExtension("igo")
I then wrote the movie into this directory and almost have the same code as you.
Do take into consideration that you need to create the igo folder and then save the movie into this folder. If you try to refer to the folder you have the movie in, your app will not read the movie file and nothing will be posted. When it is a movie file from the photo library, use an AVExportSession and export it to the postingPath.
self.instagramController = UIDocumentInteractionController.init(url: postingPath)
self.instagramController.uti = "com.instagram.exclusivegram"
self.instagramController.delegate = self
self.instagramController.presentOpenInMenu(from:
self.navigationItem.rightBarButtonItem!, animated: true)
However, you do need to make your class posting to instagram adhere to the UIDocumentInteractionControllerDelegate, otherwise you need cast self. You also need to include Social. I don't think you have done anything wrong in the second part of this post, because you would have gotten xcode errors and warnings.
I hope the first part can help you further, since I don't think the second part has given you problems.
I have a url document url list in a TableViewController` like this one
https://lists.w3.org/Archives/Public/uri/2004Nov/att-0015/App-Note-UseOfTheFileURLInJDF-031111.doc
and on TableViewCell selection this doc file should open in any default viewer that is not part my app, So I can do achieve this ? Is this possible or any suggestion.
Working with QuickLook Framework should satisfied your requirement.
As mentioned at "Using the Quick Look Framework":
A Quick Look preview controller can display previews for the following
items:
iWork documents
Microsoft Office documents (Office ‘97 and newer)
Rich Text Format (RTF) documents
PDF files
Images
Text files whose uniform type identifier (UTI) conforms to the public.text type
Comma-separated value (csv) files
You can find many of articles about working with QuickLook Framework; You might want to check the following one:
Using Quick Look Framework for Previewing Documents.
Also, checking this repo (GitHub) might be useful.
Hope this helped.
Use UIWebView class to open the given URL.
Method 1:
let webView = UIWebView(frame: self.view.frame)
webView.scalesPageToFit = true
view.addSubview(webView)
let urlS = "https://lists.w3.org/Archives/Public/uri/2004Nov/att-0015/App-Note-UseOfTheFileURLInJDF-031111.doc"
let url = URL(string: urlS)
let request = URLRequest(url: url!)
webView.loadRequest(request)
Method 2:
With this method, you'll get nice ToolBar items, which you can customize based on your requirement.
Using UIWebView library for Swift, SwiftWebView:

I want to use an action extension to transfer a PDF file from Safari to my host application.
If the user opens a PDF file in Safari, the extension should copy the local file to my app.
Somehow the NSItemProvider only has Items conforming to the type 'public.url'.
This is the web-URL to the file, but not the local filepath that I want.
Can someone point me in the right direction here?
I came across the same scenario yesterday. What I did was
let url: URL = (result as? URL)!
let path: String = url.path
if path.hasSuffix(".pdf") {
//download the data from url and write to a pdf file
}
