Implementing date to a toggle button

Question

I want to apply the current date as title to a button once it is tapped by the user. I already have the button read "USED" once clicked, but I want it to include the date too. For example, the button is clicked on January 1st 2018, how would I get it to read "USED 01/01/18"? And on the contrary, if it was used the second of january it would need to read "USED 01/02/18" My code for the toggle button is included below, my particular button only toggles once.

var didClick: Bool = false

@IBAction func special1BTNpressed(_ sender: UIButton) {
    if !didClick {
        didClick = true
        sender.setTitle("USED", for: .normal)
    }
}

This sounds like you want to store this date when your app gets terminated? You can see how to get the current date here: https://stackoverflow.com/questions/24070450/how-to-get-the-current-time-as-datetime — Teetz, Aug 06 '18 at 17:58

Combining your question and zulutime's answer you could use the following:

import UIKit

class MyViewController: UIViewController {

    var didClick: Bool = false

    @IBAction func special1BTNpressed(_ sender: UIButton) {

        if !didClick {
            didClick = true

            let date = Date()
            let formatter = DateFormatter()
            formatter.dateFormat = "MM/dd/yyyy"
            let result = formatter.string(from: date)

            sender.setTitle("USED " + result, for: .normal)
        }
    }
}

@JimHalpert Glad i could help. If it's working i would appreciate it if you accept my answer. — Teetz, Aug 07 '18 at 18:18

You can use a DateFormatter to get the current date and format it

import Foundation

class MyViewController: UIViewController {
    var didClick: Bool = false
    @IBAction func special1BTNpressed(_ sender: UIButton) {
        if !didClick {
            didClick = true

            let date = Date()
            let formatter = DateFormatter()
            formatter.dateFormat = "MM/dd/yyyy"
            let result = formatter.string(from: date)

            sender.setTitle("USED " + result, for: .normal)
        }
    }
}

Thanks for your answer, but code only answers are rarely helpful to others and are usually deleted. Please update your answer with an explanation of your code. – divibisan Aug 06 '18 at 18:54
do i have to declare something in the ViewController? @zulutime – Jim Halpert Aug 06 '18 at 22:23
im getting an error in the line that reads formatter.dateFormat = "MM/dd/yyyy" @zulutime – Jim Halpert Aug 06 '18 at 22:23
it says expected declaration error in that line @zulutime – Jim Halpert Aug 06 '18 at 22:30
I think you need to "import Foundation" – zulutime Aug 07 '18 at 02:03
try it on an online playground this snippet first without the UIView and subclasses – zulutime Aug 07 '18 at 02:05
didn't work, i don't know how to use online playground i just need a solution that can be incorporated into my code @zulutime – Jim Halpert Aug 07 '18 at 04:48
did you put it inside the button action function? I just edited the code – zulutime Aug 07 '18 at 06:46
