Cancel button instead of a back button in Navigation Controller

ios, storyboard, swift, uibarbuttonitem, xcode

Solution

You just have to select your UIBarButtonItem, click at show Attributes Inspector, click at Identifier and select "Cancel" from the drop-down menu.

@IBAction func cancelDownload(sender: AnyObject) {
    dismissViewControllerAnimated(true, completion: nil)

}

Problem

I have a general question concerning the navigation between views. I have a view controller 1 embeded in a navigation controller. In the nav bar, I have a button to do add data, when pushed, it goes to view controller 2 through segue Show (in Storyboard). In view controller 2, I return to view controller 1 after collecting data when I click the button save in nav bar on the right. I collect data with: ``` override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {...} ``` I would prefer instead of a back button to have a cancel button in the view controller 2 to return to view controller 1. I feel something is wrong in my design but I dont know what. In fact I am looking for something very similar to app clock. Do you have any idea? Edit: Here is the story board. you will notice the loop beween the two controller. how to do when I click save to not have a back button automatically on the first controller?
