Perform push segue after an unwind segue

Question

I am working on a camera app where the camera views are shown modally. After I am done with cropping. I perform an unwind segue to the MainPageViewController. (

Answer 1

I'm guessing the performSegue is not firing because the unwind segue has not yet finished. The only thing I can think of at the moment, is to delay calling the performSegue using dispatch_after. This seems very "hacky" to me though.

@IBAction func unwindToMainMenu(segue: UIStoryboardSegue) {
    dispatch_after(1, dispatch_get_main_queue()) { () -> Void in
        self.performSegueWithIdentifier("Categories", sender: self)
    }
}
