Loading PDF From Documents URL - ios

Question

I seem to be having issues while loading a PDF to my WebView in Swift.
Printing out all the files in the Documents directory results in:
file:///Users/adriandavidsmith/Library/Developer/CoreSimulator/Devices/B537EBE4-14AE-439A-B84B-31342E233367/data/Containers/Data/Application/E791BF20-CC53-4FBB-B34A-F73CED74EB5D/Documents/DOCUMENT.pdf
However, when I attempt to load that file into a WebView nothing gets shown. As if it is unable to find the file.
if let pdf = NSBundle.mainBundle().URLForResource("DOCUMENT", withExtension: "pdf", subdirectory: "Documents", localization: nil){
let req = NSURLRequest(URL: pdf)
webView.loadRequest(req)
Any thoughts/ideas?

Answer 1

Swift 3 compatible
var pdfURL = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)).last! as URL
pdfURL = pdfURL.appendingPathComponent( "example.pdf") as URL
let data = try! Data(contentsOf: pdfURL)
let webView = WKWebView(frame: CGRect(x:20,y:20,width:view.frame.size.width-40, height:view.frame.size.height-40))
webView.load(data, mimeType: "application/pdf", characterEncodingName:"", baseURL: pdfURL.deletingLastPathComponent())
view.addSubview(webView)

The E791BF20-CC53-4FBB-B34A-F73CED74EB5D is application folder in which you have Documents folder containing the pdf file which you want to view.
This will give path of Documents folder.
let fileManager = NSFileManager.defaultManager()
let documentsUrl = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as NSURL
print(documentsUrl)
You need to change code
let pdf = documentsUrl + "/<your pdf file name>"
let req = NSURLRequest(URL: pdf)
webView.loadRequest(req)
Hope this works for you.

You are fetching it from bundle not from document directory.
Try this....
var pdf = (NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)).last as? NSURL
pdf = pdf?.URLByAppendingPathComponent( "ST_Business%20Times_07022016.pdf")
let req = NSURLRequest(URL: pdf)
webView.loadRequest(req)

Please check you path has valid file exist or not before loading the file.
let webView : UIWebView!
webView = UIWebView()
webView.frame = self.view.bounds
self.view.addSubview(webView)
let PDF_FILE_PATH = NSBundle.mainBundle().pathForResource("ST_Business%20Times_07022016", ofType: "pdf")
let checkValidation = NSFileManager.defaultManager()
if (checkValidation.fileExistsAtPath(PDF_FILE_PATH!))
{
print("FILE AVAILABLE");
let req = NSURLRequest(URL: NSURL(string: PDF_FILE_PATH!)!)
webView.loadRequest(req)
}
else
{
print("FILE NOT AVAILABLE");
}
