How to open the iPhone calendar from within my app?

Question

I want to be able to implement a button in my app, that quits my app, and takes the user to the iPhone's calendar. I'm not interested in sending the user to a specific event. Just opening up the calendar would do the trick. Any suggestions?

Answer 1

Hey might be a late answer but you can do it now like this

 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"calshow://"]];

Answer 2

According to the comments on this blog post, there is currently no way to launch the calendar app.
