How to loop NSTimer in SWIFT with a specific number of counting - swift

Question

I am trying to loop a timer with a specific number of counting...
eg... 1, 2, 3, 4, 5
then loop again, the same counting, 10 times, then stop.
I was able to do the counting, but I can't do the looping of the counting.
What am I doing wrong?
var times = 0
var stopCounting = 10
#IBAction func buttonPressed(sender: UIButton) {
self.startTimer()
}
func startTimer(){
self.timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: Selector("startCounting"), userInfo: nil, repeats: true)
}
func startCounting (){
times += 1
if times < stopCounting + 1{
if counter > -1 && counter < 6 {
counting.text = String(counter++)
} else if counter == Int(counting.text) {
counting.text = "0"
}
}

import UIKit
class ViewController: UIViewController {
#IBOutlet weak var strTime: UILabel!
var timer = NSTimer()
var endTime: NSTimeInterval = 0
var now: NSTimeInterval { return NSDate().timeIntervalSinceReferenceDate }
var times = 0
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func updateText(){
let time = Int(ceil(endTime - now))
if time == 0 {
times++
if times == 10 {
strTime.text = "end"
timer.invalidate()
}
endTime = NSDate().timeIntervalSinceReferenceDate + 5
} else {
strTime.text = time.description
}
}
#IBAction func buttonPressed(sender: UIButton) {
timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: "updateText", userInfo: nil, repeats: true)
endTime = NSDate().timeIntervalSinceReferenceDate + 5
sender.hidden = true
}
}
to make it count from 1 to 5 you need to change from ceil to floor, abs() and add +1
func updateText(){
let time = Int(floor(abs(endTime - now - 5)))
if time == 5 {
times++
if times == 10 {
strTime.text = "10" + " " + "0"
timer.invalidate()
}
endTime = NSDate().timeIntervalSinceReferenceDate + 5
} else {
strTime.text = times.description + " " + (time+1).description
}
}

Never done swift, but took a stab in the dark, why not.
var loops = 5 // Number of times to loop the counting
var countTo = 10 // Number to count to
var loopCount = 0 // Number of loops
#IBAction func buttonPressed(sender: UIButton) {
self.timer = NSTimer.scheduledTimerWithTimeInterval(1.0,
target: self,
selector: Selector("startCounting"),
userInfo: nil,
repeats: true)
}
func startCounting (){
// Loop from 1 to countTo, setting the text for each number
for i in 1..countTo {
counting.text = String(i)
}
// Done counting, reset to zero
counting.text = "0"
// Update the number of times the counting has run
loopCount++
// If have completed all the loops, invalidate the timer
if (loopCounter >= loops) {
self.timer.invalidate()
}
}
