How can I pause and resume NSTimer.scheduledTimerWithTimeInterval in swift?

Question

I\'m developing a game and I want to create a pause menu. Here is my code:

self.view?.paused = true

but NSTimer.scheduledTimerWithT

Answer 1

To start

timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(ViewController.action), userInfo: nil, repeats: true)

To pause

timer.invalidate()

To reset

time += 1
label.text = String(time)

'label' is the timer on output.
