    if ( urlData )
    {
        NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString  *documentsDirectory = [paths objectAtIndex:0];

        NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"filename.pdf"];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSDirectoryEnumerator *direnum = [[NSFileManager defaultManager] enumeratorAtPath:documentsDirectory];

    NSString *documentsSubpath;
    while (documentsSubpath = [direnum nextObject])
    {
        if (![documentsSubpath.lastPathComponent isEqual:searchFilename]) {

        }

        NSLog(@"found %@", documentsSubpath);
    }


}

You can browse only .pdf present IN YOUR APP. You know yourself where are the .pdf, so what's your issue? — Larme, Sep 07 '16 at 10:11
You can't. It's called sandboxing, and iOS doesn't have a "Finder.app"/Explorer equivalent. See there: http://stackoverflow.com/questions/38873128/how-to-choose-pdf-file-in-ios — Larme, Sep 07 '16 at 10:14
If you want you can choose your .pdf file in mail using UIDocumentInteractionController. — Kamlesh Shingarakhiya, Sep 07 '16 at 10:20

Add this delegate method: UIDocumentInteractionControllerDelegate
Use it like this:

UIDocumentInteractionController *viewer = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path_of_doc]]; viewer.delegate = self; [viewer presentPreviewAnimated:YES];

Hope this helps you. Let me know if you want to download the file from app itself and store it in doc dir.

1. Try fetching all the files from doc dir/ fetch only pdf files from do dir. 2. filter for pdf, then show it in collection view. 3. when user will tap on one of those you can get the link from collection view delegate method, then upload the file as metadata to the server. – Abhi Sep 07 '16 at 12:41
4. Try this, use your ext i.e. pdf to filter the array of doc you get: -(NSArray *)findFiles:(NSString *)extension{ NSMutableArray *matches = [[NSMutableArray alloc]init]; NSFileManager *fManager = [NSFileManager defaultManager]; NSString *item; NSArray *contents = [fManager contentsOfDirectoryAtPath:[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] error:nil]; // >>> this section here adds all files with the chosen extension to an array for (item in contents){ if ([[item pathExtension] isEqualToString:extension]) { [matches addObject:item]; } } return matches; } – Abhi Sep 07 '16 at 12:44

First of all you need to fetch list of available files in directory,

This method helps you to find files on given path.

-(NSArray *)listAllFileAtPath:(NSString *)path{

//----LIST OF AVAILABLE FILES----//
int count;

NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:NULL];

return directoryContent;}

Now you can filter pdf files from it then you can use below link to attach file and send the email.

For that you need to design a separate view in that can use UICollectionView which can shows thumb image of first page of pdf and on click you can send email with attachment of it. – Samkit Shah Sep 07 '16 at 12:06
