Supporting Open In… menu item in my app for iOS Mail And Safari
I'm working on an application that will download files from the Internet, for further use.
How do I launch my own app when a link is pressed on Safari?
For example, when a .pdf file link is shown in safari the user clicks it and the file is downloaded. After that there is the suggestion to "Open in", followed by a list of possible applications, like iBooks. I want my app to be displayed among these options.
