open iBooks from my app

Question

I have some PDF in my app. I want to provide an option to open those PDF in other third party e-readers app that might be installed on the device, like Stanza and iBooks.

Answer 1

You don't need to detect the other apps, you need to know the url that can open them.

A call like this:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.apple.com"]];

Tells the phone to open the page in whatever app handles http/html requests which is safari. iBooks has their own url format which hopefully you can track down.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"ebook://iRobot.pdf"]];

NOTE: that's not correct, just meant to illustrate a different url scheme.
