title: iOS 8 Remove today extension
body: <p>I created a today extension coded in Objective c and I have decided that I do not want it in my app. I removed the scheme, the target and all the files that were associated with it, yet it remained in my notification center. I deleted the app and it was no longer in the notification center, then when I ran the app again it was back. Im afraid that when I submit the app there will be an empty widget as an option to add to notification center. Does anybody know how I can completely delete the extension from the app? Thanks! </p>
