Man this cancel button does nothing at all other than dismissing action sheet. If you want to get rid of mail composer you have to press cancel at upper left corner which shows you an action sheet at the bottom with options Delete Draft, Save Draft and cancel. Delete draft and save draft will dismiss the mail composer and the delegate function will be called. Cancel button will actually dismiss action sheet in order to save the mail composer from dismissing in case if user accidentally clicked that cancel button at the top
