ios - use an array to pass values into a TIMER IN SWIFT -


i have working countdown can increase pushing add button , thats time counts down (so user can set countdown)

i display starting time 00:00 in label.

when click button increase countdown begins @ 1 because @ moment int

can create array , increase individual indexes, display them within label?

can or point me in write code direction have below thanks

var timearray: [double : double] =  [00, 00]   var timer = nstimer() var countdown = 0  func runtimer() {   timer = nstimer.scheduledtimerwithtimeinterval(1, target: self,      selector:selector("updatetimer"), userinfo: nil, repeats: true)  }   func updatetimer() {    if countdown > 0 {       countdown--       timerlabel.text = string(countdown)      } else {         countdown = 0          timerlabel.text = string(countdown)    }  }  @iboutlet weak var timerlabel: uilabel!   @ibaction func increasecountdown(sender: anyobject) {  countdown++ timerlabel.text = string(countdown)   }   @ibaction func startcountdown(sender: anyobject) {   runtimer()  }   @ibaction func stopcountdown(sender: anyobject) {      timer.invalidate()  }     override func viewdidload() { super.viewdidload() // additional setup after loading view, typically nib. }  override func didreceivememorywarning() {    super.didreceivememorywarning()      // dispose of resources can recreated.    }   } 

your syntax timearray creating dictionary , not array. suggest use int instead of double:

var timearray:[int] = [0, 0] 

to create label text field:

// format create string 2 digits minute , second // leading 0 each if needed "00:00" timerlabel.text = string(format: "%02d:%02d", timearray[0], timearray[1]) 

when create timer, convert time array simple countdown:

let countdown = timearray[0] * 60 + timearray[1] 

an entirely different approach work store time integer seconds internally , display minutes , seconds.

let countdown = 100 // 1 minute, 40 seconds timerlabel.text = string(format: "%02d:%02d", countdown/60, countdown%60)
