How can I make a countdown with an NSTimer using Swift?
451
Underneath the timerLabel outlet create the following variables: var seconds = 60 //This variable will hold a starting value of seconds. It could be any amount above 0. var timer = Timer() var isTimerRunning = false //This will be used to make sure only one timer is created at a time.
Creating a non-repeating timerlet timer1 = Timer. scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(fireTimer), userInfo: nil, repeats: false) let timer2 = Timer. scheduledTimer(withTimeInterval: 1.0, repeats: false) { timer in print("Timer fired!") }
Question 1:
@IBOutlet var countDownLabel: UILabel! var count = 10 override func viewDidLoad() { super.viewDidLoad() var timer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(UIMenuController.update), userInfo: nil, repeats: true) } func update() { if(count > 0) { countDownLabel.text = String(count--) } } Question 2:
You can do both. SpriteKit is the SDK you use for scene, motion, etc. Simple View Application is the project template. They should not conflict
