Using x-apple-reminder:// to launch the Reminders app in iOS

Question

Seems simple but I can't make this work.. I want to launch the native Reminders app from my native app.

From what I've read I need to use x-apple-reminder:// URL scheme but it does not launch the Reminders app.

Here's my code:

NSString* reminderUrl = @"x-apple-reminder://";
NSURL *url = [NSURL URLWithString:reminderUrl];
BOOL ok = [[UIApplication sharedApplication] openURL:url];

ok is always NO and nothing happens.

I also tried passing in the Reminder's id (my app created it), but that didn't work. (as in x-apple-reminder://REMINDER_GUID)

I suspect that my problem is with the openURL call.. is there some other option?

By the way, apparently, Apple is against using undocumented URL schemes, take a look:

Available schemes are documented here:
