I need to share/open some different files under iOS e.g. an image to iCloud or an pdf to iBooks. There are several examples around for text and images but nothing for somewhat else...
I created my own UIActivityItemProvider
; simplified version here:
class MyItemProvider: UIActivityItemProvider {
override func item() -> AnyObject {
self.placeholderItem
}
override func activityViewController(activityViewController: UIActivityViewController, dataTypeIdentifierForActivityType activityType: String?) -> String {
return kUTTypePDF as String
}
func activityViewControllerPlaceholderItem(activityViewController: UIActivityViewController) -> AnyObject {
return self.placeholderItem
}
}
And start sharing with something like:
let myPDF = NSData(contentsOfURL: NSBundle.mainBundle().URLForResource("testpdf", withExtension: "pdf")) {
let activityVC = UIActivityViewController(activityItems: [MyItemProvider(placeHolder: myPDF)], applicationActivities: nil)
self.presentViewController(activityVC, animated: true, completion: nil)
I expect a sharedialog like:
But all I get is:
Any suggestions?

I've spent a lot of time thinking ways to share a PDF file within UIWebView loaded from a URL, like "http://youPdfFile.pdf"
After a coupe of days, I've found what I think it's the most suitable way:
1) The PDF must first be saved in the file system. For example, this can be done after loading the UIWebView:
class yourViewController: UIViewController{
var documentPathToLoad = "http://youPdfFile.pdf"
...
func webViewDidFinishLoad(_ webView: UIWebView) {
if yourWebView.isLoading {
// still loading
return
}
//Save the pdf document to file system
savePdf()
}
func savePdf(){
let fileManager = FileManager.default
let paths = (NSSearchPathForDirectoriesInDomain((.documentDirectory, .userDomainMask, true)[0] as NSString).appendingPathComponent("documento.pdf")
let pdfDoc = NSData(contentsOf:URL(string: documentPathToLoad)!)
fileManager.createFile(atPath: paths as String, contents: pdfDoc as Data?, attributes: nil)
}
}
2) Read the saved file and then share it. This method works for me in Swift 3.0.1:
func loadPDFAndShare(){
let fileManager = FileManager.default
let documentoPath = (self.getDirectoryPath() as NSString).appendingPathComponent("documento.pdf")
if fileManager.fileExists(atPath: documentoPath){
let documento = NSData(contentsOfFile: documentoPath)
let activityViewController: UIActivityViewController = UIActivityViewController(activityItems: [documento!], applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView=self.view
present(activityViewController, animated: true, completion: nil)
}
else {
print("document was not found")
}
}
The existing answers demonstrate how to share a PDF using a local file's URL. However you don't have to create a file if you don't want to. The alternative is to use Data
representation of your PDF file.
Let's say your're using PDFKit
to display PDFs in UI. It means that you would deal with PDFKit.PDFDocument
class which has dataRepresentation()
method. This method returns Data
which can be passed to UIActivityViewController
initialiser.
You have to pass pdf file url for pdf supported applications' options in UIActivityViewController.
func btnTapped() {
if let pdf = Bundle.main.url(forResource: "yourPdfFileName", withExtension: "pdf", subdirectory: nil, localization: nil) {
self.sharePdf(path: pdf)
}
}
func sharePdf(path:URL) {
let fileManager = FileManager.default
if fileManager.fileExists(atPath: path.path) {
let activityViewController: UIActivityViewController = UIActivityViewController(activityItems: [path], applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView = self.view
self.present(activityViewController, animated: true, completion: nil)
} else {
print("document was not found")
let alertController = UIAlertController(title: "Error", message: "Document was not found!", preferredStyle: .alert)
let defaultAction = UIAlertAction.init(title: "ok", style: UIAlertAction.Style.default, handler: nil)
alertController.addAction(defaultAction)
UIViewController.hk_currentViewController()?.present(alertController, animated: true, completion: nil)
}
}
