Download PDF and Save to the "Files" in Iphone, Not to the App Data, Swift

Download PDF and save to the Files in iPhone, not to the app data, Swift

Here's how to download any files and save to Photos(if image file) or Files (if pdf)

let urlString = "your file url"
let url = URL(string: urlString)
let fileName = String((url!.lastPathComponent)) as NSString
// Create destination URL
let documentsUrl:URL =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
let destinationFileUrl = documentsUrl.appendingPathComponent("\(fileName)")
//Create URL to the source file you want to download
let fileURL = URL(string: urlString)
let sessionConfig = URLSessionConfiguration.default
let session = URLSession(configuration: sessionConfig)
let request = URLRequest(url:fileURL!)
let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
    if let tempLocalUrl = tempLocalUrl, error == nil {
        // Success
        if let statusCode = (response as? HTTPURLResponse)?.statusCode {
            print("Successfully downloaded. Status code: \(statusCode)")
        }
        do {
            try FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl)
            do {
                //Show UIActivityViewController to save the downloaded file
                let contents  = try FileManager.default.contentsOfDirectory(at: documentsUrl, includingPropertiesForKeys: nil, options: .skipsHiddenFiles)
                for indexx in 0..<contents.count {
                    if contents[indexx].lastPathComponent == destinationFileUrl.lastPathComponent {
                        let activityViewController = UIActivityViewController(activityItems: [contents[indexx]], applicationActivities: nil)
                        self.present(activityViewController, animated: true, completion: nil)
                    }
                }
            }
            catch (let err) {
                print("error: \(err)")
            }
        } catch (let writeError) {
            print("Error creating a file \(destinationFileUrl) : \(writeError)")
        }
    } else {
        print("Error took place while downloading a file. Error description: \(error?.localizedDescription ?? "")")
    }
}
task.resume()

Saving PDF Files with Swift in iOS and display them

Since several people requested this, here is the equivalent to the first answer in Swift:

//The URL to Save
let yourURL = NSURL(string: "http://somewebsite.com/somefile.pdf")
//Create a URL request
let urlRequest = NSURLRequest(URL: yourURL!)
//get the data
let theData = NSURLConnection.sendSynchronousRequest(urlRequest, returningResponse: nil, error: nil)

//Get the local docs directory and append your local filename.
var docURL = (NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)).last as? NSURL

docURL = docURL?.URLByAppendingPathComponent( "myFileName.pdf")

//Lastly, write your file to the disk.
theData?.writeToURL(docURL!, atomically: true)

Also, since this code uses a synchronous network request, I highly recommend dispatching it to a background queue:

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), { () -> Void in
    //The URL to Save
    let yourURL = NSURL(string: "http://somewebsite.com/somefile.pdf")
    //Create a URL request
    let urlRequest = NSURLRequest(URL: yourURL!)
    //get the data
    let theData = NSURLConnection.sendSynchronousRequest(urlRequest, returningResponse: nil, error: nil)

    //Get the local docs directory and append your local filename.
    var docURL = (NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)).last as? NSURL

    docURL = docURL?.URLByAppendingPathComponent( "myFileName.pdf")

    //Lastly, write your file to the disk.
    theData?.writeToURL(docURL!, atomically: true)
})

And the answer to second question in Swift:

//Getting a list of the docs directory
let docURL = (NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).last) as? NSURL

//put the contents in an array.
var contents = (NSFileManager.defaultManager().contentsOfDirectoryAtURL(docURL!, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions.SkipsHiddenFiles, error: nil))
//print the file listing to the console
println(contents)

    let fileName = String((url!.lastPathComponent)) as NSString
    //Mark:  Create destination URL
    let documentsUrl:URL =  (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL?)!
    let destinationFileUrl = documentsUrl.appendingPathComponent("\(fileName)")
    //Mark: Create URL to the source file you want to download
    let fileURL = URL(string: urlString)
    let sessionConfig = URLSessionConfiguration.default
    let session = URLSession(configuration: sessionConfig)

    let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
        if let tempLocalUrl = tempLocalUrl, error == nil {
            //Mark: Success
            if let statusCode = (response as? HTTPURLResponse)?.statusCode {
                print("Successfully downloaded. Status code: \(statusCode)")
            }
            do {

                    for indexx in 0..<contents.count {
                        if contents[indexx].lastPathComponent == destinationFileUrl.lastPathComponent {
                            let activityViewController = UIActivityViewController(activityItems: [contents[indexx]], applicationActivities: nil)
                            self.present(activityViewController, animated: true, completion: nil)
                        }

                }
            } catch (let writeError) {
                print("Error creating a file \(destinationFileUrl) : \(writeError)")
            }
        } else {
            print("Error took place while downloading a file. Error description: \(error?.localizedDescription ?? "")")
        }
    }
    task.resume()

Download PDF file and save in document directory

You need to move the file to your custom location after the download. Implement URLSessionDownloadDelegate and you will receive the location of your downloaded file.

Delegate method:

func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL)

Code to move the file:

do {
    let documentsURL = try
        FileManager.default.url(for: .documentDirectory,
                                in: .userDomainMask,
                                appropriateFor: nil,
                                create: false)

    let savedURL = documentsURL.appendingPathComponent("yourCustomName.pdf")
    try FileManager.default.moveItem(at: location, to: savedURL)
} catch {
    print ("file error: \(error)")
}

How to download PDF and store it locally on iPhone?

I have found one method which I tried myself:

// Get the PDF Data from the url in a NSData Object
NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[
    NSURL URLWithString:@"http://www.example.com/info.pdf"]];

// Store the Data locally as PDF File
NSString *resourceDocPath = [[NSString alloc] initWithString:[
    [[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent]
        stringByAppendingPathComponent:@"Documents"
]];

NSString *filePath = [resourceDocPath 
    stringByAppendingPathComponent:@"myPDF.pdf"];
[pdfData writeToFile:filePath atomically:YES];

// Now create Request for the file that was saved in your documents folder
NSURL *url = [NSURL fileURLWithPath:filePath];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

[webView setUserInteractionEnabled:YES];
[webView setDelegate:self];
[webView loadRequest:requestObj];

This will store your PDF locally and load it into your UIWebView.
