UITapGestureRecognizer Add Coordinates to an Array - ios

Question

I have an ImageView inside of a ScrollView.
Each time the user clicks on a point on the image a pin is set and the coordinates are printed out.
However, I'm trying to store multiple coordinates inside of an array.
The first 3 times the user clicks on the image, I need the coordinates to store inside refs1. The next 14-20 times inside spots1.
// MARK: - Outlets
#IBOutlet weak var scrollView: UIScrollView!
#IBOutlet weak var sharkImage: UIImageView!
// MARK: - Properties
var refs1 :[Double] = []
var spots1 :[Double] = []
// MARK: - View Did Load
override func viewDidLoad() {
super.viewDidLoad()
scrollView.minimumZoomScale = 1.0
scrollView.maximumZoomScale = 6.0
scrollView.delegate = self
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(tapAction))
self.sharkImage.isUserInteractionEnabled = true
self.sharkImage.addGestureRecognizer(tapGestureRecognizer)
}
// MARK: - Scroll View
func viewForZooming(in scrollView: UIScrollView) -> UIView? {
return sharkImage
}
// MARK: - Functions
func tapAction(sender: UITapGestureRecognizer) {
// Get points for the UIImageView
let touchPoint = sender.location(in: self.sharkImage)
print(touchPoint)
// Add pin to tap
let pin = UIImageView(frame: CGRect(x: touchPoint.x - 5, y: touchPoint.y - 5, width:10, height:10))
pin.image = UIImage(named: "photo-pin-red")
sharkImage.addSubview(pin)
}

Answer 1

Well first of all you could store the coordinates in a 2D array if you want to:
var refs1 :[[Double]] = []
var spots1 :[[Double]] = []
Then store a global variable called counter to keep track of the click count:
var counter = 0
And then in your tapAction do the following (see comments for descriptions):
func tapAction(sender: UITapGestureRecognizer) {
// increase counter with +1 for each click
counter += 1
if counter <= 3 { // first 3
refs1.append([Double(touchPoint.x), Double(touchPoint.y)])
} else if counter <= 23 { // next 14 - 20 clicks
counter = 0 // reset counter to start over again
spots1.append([Double(touchPoint.x), Double(touchPoint.y)])
}
}

Answer 2

Use a counter variable:
var count = 0
func tapAction(sender: UITapGestureRecognizer) {
count = conut + 1
// Check for count
if (count >= 14) {
// Do stuff
}
// Get points for the UIImageView
let touchPoint = sender.location(in: self.sharkImage)
print(touchPoint)
// Add pin to tap
let pin = UIImageView(frame: CGRect(x: touchPoint.x - 5, y: touchPoint.y - 5, width:10, height:10))
pin.image = UIImage(named: "photo-pin-red")
sharkImage.addSubview(pin)
}
