I know how to implement inter-app communication. I did it with some examples.

Now I need to send/share a doc/xls file with other application in my iPad/iPhone that have url schemes to open in such files.

Questions

  1. How Can I find the list of application that has url schemes to open such files.
  2. How can I limit the open-in in some specified application with in the above list.

Important

  1. How can I prevent the shared document from further sharing (such as email/print).
  2. And if the shared file is modified by that application how can I know it.
  3. How can I get back the shared file after modification.
  4. While sharing is there is any option to make it as read-only,read-write privilege.

  • In general, it is impossible to prevent a document from being shared. You can only make it more frustrating.

  • Everything else depends on the URL scheme you are using. For example, if it is the file:// scheme then access is controlled by the OS and filesystem. If it is the http:// scheme then access is controlled by the HTTP server, etc.

  • Hi Dietrich thanks, But I am thinking in case of inter-app communication using openURL: – Naveen Shan Aug 30 '11 at 09:06
  • That is what I am talking about. Just because an API uses URLs does not make it any easier to prevent it from being shared. And the access control / modification notifications are all done through the URL's protocol. – Dietrich Epp Aug 30 '11 at 09:11
  • Dietrich, I saw some apps can define url scheme that can accept files(pdf, doc) How can I do this?. with such privillages any idea? see this : http://wiki.akosma.com/IPhone_URL_Schemes – Naveen Shan Aug 30 '11 at 09:14
  • If you create a URL scheme for your app it is so other applications can control your app, not the other way around. – Dietrich Epp Aug 30 '11 at 09:16
