How to close a View Controller after Performing segue in Xcode? - ios

Question

My storyboard looks something like this:-
Main View Controller -> Game View Controller -> Game Result View Controller
I have performed a modal segue from Main V.C to the Game V.C. Now when I perform a modal segue from Game V.C. to Game Result V.C., the Game V.C. is not closing and since the Game V.C. detects if touches began, it crashes when it detects touch outside the Game V.C. after performing a modal segue to the Game Result V.C. I am not using a navigation View Controller. Could anyone please help me on how shall I close the Game V.C after performing a modal segue to the Game Result V.C.? Would appreciate your help! Thanks:)
**Game V.C.**
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
// First touch to start the game
if gameState == .ready {
startGame()
}
if let touchLocation = event?.allTouches?.first?.location(in: self.view) {
// Move the player to the new position
movePlayer(to: touchLocation)
// Move all enemies to the new position to trace the player
moveEnemies(to: touchLocation)
}
}
func gameOver() {
stopGame()
performSegue(withIdentifier: "2to3segue", sender: self)
}

Answer 1

Some tips:
Method 1
You can use Tap controller, let storyboard works as following
Main View Controller -> (tab-1) Game View Controller
\
-> (tab-2) Game Result View Controller
Hide tab bar, and change tab by program.
I suggest to use method 1.
Method 2
Dismiss Game View Controller, WITHOUT animation. And then present Game Result View Controller WITH animation.
But, I remember method 2 has some problems. I used it before, and finally I use method 1 now.
// Example:
// Two or more animations will produce problem.
v2.dismiss(animated: false, completion: nil);
v.present(v3, animated: true, completion: nil);

Answer 2

First dismiss the "v2" view controller and in completion block present "v3" view controller
v2.dismiss(animated: false, completion: {
v.present(v3, animated: true, completion: nil)
})
or
if v2 is your presented view controller then :
self.presentedViewController.dismiss(animated: false, completion: {
v.present(v3, animated: true, completion: nil)
})
