Hi,

This is great! I'd like to write an app that lists my reminders by sorting them (and even filter them) in different ways. Also, I'd like to be able to set certain reminders to completed.

How can I do this?

Thanks,
Daniel

Do you have any way to handle if the user denies the request? For me once they select cancel I can't change the status and resubmit the request.

Its much faster in a background thread.

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
    // code here
}

thanks

I noticed you saved the event with the notes. I was able to do this successfully as well as it shows up in my Calendar. However, if I'm trying to retrieve the data and display it on a UITableView. The only thing that isn't accessible is the notes. Is there a trick to gain access to the notes? I noticed you didn't show how to do it either even though you saved it.

Thanks
