Custom URL Schemes on iOS and PDFpen

This is not an explanation of custom URL schemes, it is simply a resource on how to use  PDFpen in iOS with them. This applies to PDFpen for iPad and PDFpen for iPhone.

Open the PDFpen app
pdfpen://

• When used with an invalid file name this will just open the app.

Open a document, named "Panther", stored locally in the main Documents view.
pdfpen:///Panther.pdf

• Three slashes /// are used for local files in the Documents view.
• The file name is case sensitive.
• A file extension is needed along with the file name. This will usually be ".pdf".

Open a document, named "Panther," to a specific page, page 3.
pdfpen:///Panther.pdf?pg=3

• Append "?pg=" and the page number

Open a document, named "Leopard", stored locally in a folder named "Big Cats." 
pdfpen:///Big%20Cats/Leopard.pdf

Open a document, named "Grey Wolf," in the Dropbox folder named "Wolves."
pdfpen://Dropbox/Wolves/Grey%20Wolf.pdf

• Use two slashes // with files not stored locally.

For sub-folders, extend the file path to include them.
pdfpen://Dropbox/Wolves/Habitat/Tundra.pdf
