ボタン機能付きタイマー？

Question

誰かがこの機能を自分のコードに追加できますか？

タップされているボタンに関連するビューコントローラの上部にタイマーが必要です。このタイマーは、ボタンを1日に1回だけ押すことができます。どうすればこのことができますか？

ここに私のView Controllerコードがあります。

サンプルコードは

import UIKit 

class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource { 

    @IBOutlet var emojiPickerView: UIPickerView! 
    @IBOutlet var spinButton: UIButton! 


    var emojiArray = ["", "", "", "", "", "", "", "", "", ""] 
    var reelArray0 = [Int]() 
    var reelArray1 = [Int]() 
    var reelArray2 = [Int]() 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     emojiPickerView.delegate = self 
     emojiPickerView.dataSource = self 

     setUpUI() 
     addRandomNumbersToReelArrays() 

     // Set reels to middle positions 
     for i in 0...2 { 
      selectEmojiPickerComponentRow(50, component: i) 
     } 
    } 

    func setUpUI() { 
     spinButton.layer.cornerRadius = 15 
     spinButton.layer.shadowColor = UIColor.black.cgColor 
     spinButton.layer.shadowOffset = CGSize(width: 0.0, height: 4.0) 
     spinButton.layer.shadowOpacity = 0.5 
     spinButton.layer.shadowRadius = 5.0 



    } 

    @IBAction func spinButtonTapped() { 

     animateSpinButton() 

     // Pick 3 random emojis 
     for i in 0...2 { 
      selectEmojiPickerComponentRow(Int(arc4random_uniform(99)), component: i) 
     } 
     showFeedbackForWinningSpin() 
    } 

    func showFeedbackForWinningSpin() { 
     if(reelArray0[emojiPickerView.selectedRow(inComponent: 0)] == reelArray1[emojiPickerView.selectedRow(inComponent: 1)] && reelArray1[emojiPickerView.selectedRow(inComponent: 1)] == reelArray2[emojiPickerView.selectedRow(inComponent: 2)]) { 
      // JACKPOT 
      spinButton.isEnabled = false 
      delay(0.8) { 
       self.showAlertForJackpot() 
       self.spinButton.isEnabled = true 
      } 
     } else if ((reelArray0[emojiPickerView.selectedRow(inComponent: 0)] == reelArray1[emojiPickerView.selectedRow(inComponent: 1)] 
      || reelArray1[emojiPickerView.selectedRow(inComponent: 1)] == reelArray2[emojiPickerView.selectedRow(inComponent: 2)]) 
      || (reelArray0[emojiPickerView.selectedRow(inComponent: 0)] == reelArray2[emojiPickerView.selectedRow(inComponent: 2)])) { 
      // Two emojis matched 
      spinButton.isEnabled = false 
      delay(0.8) { 
       self.showAlertForWin() 
       self.spinButton.isEnabled = true 
      } 
     } 
    } 

    func showAlertForJackpot() {

私はあなたの要件に、周りの仕事で来ています。それは最良の回避策ではありませんが、それは仕事の種類です。

1. ボタンを1日の変更に合わせて設定します。ここでは便利な機能です：Dateオブジェクトからあなたの日付部分（2017年6月14日）を与える

   func configureButtonForShowingOnceInADay() { 
   
       spinButton.tintColor = #colorLiteral(red: 0, green: 0.4784313725, blue: 1, alpha: 1) 
       let now = Date() 
       var savedDay: Date? 
       /* Check if the app launched for first time or not */ 
       let appLanuchedBefore = UserDefaults.standard.bool(forKey: "ApplicationDidLaunchPreviously") 
       if !appLanuchedBefore { 
        // App launched for first time, so Mark the app as launched in the UserDefaults 
        UserDefaults.standard.set(true, forKey: "ApplicationDidLaunchPreviously") 
        // When App launched for first time, it is must to have a date before today's date. 
        // A previous date is required for the button to be enabled for the first time 
        savedDay = Calendar.current.date(byAdding: .day, value: -1, to: now) 
       } else { 
        // App launched multiple times. So read the date from UserDefaults 
        savedDay = UserDefaults.standard.object(forKey: "date") as? Date 
       } 
   
       // get only the Date portion from now, not with Time 
       let today = todaysDate(date: now) 
   
       if let savedDate = savedDay { 
        if todaysDate(date: savedDate) == today { 
         // Saved date in UserDefaults matches with today. So the button should not be enabled 
         spinButton.isUserInteractionEnabled = false 
         spinButton.tintColor = #colorLiteral(red: 0.501960814, green: 0.501960814, blue: 0.501960814, alpha: 1) 
        } else { 
         // Saved date in UserDefaults doesn't match with today. So the button should be enabled 
         spinButton.isUserInteractionEnabled = true 
         spinButton.tintColor = #colorLiteral(red: 0, green: 0.4784313725, blue: 1, alpha: 1) 
         UserDefaults.standard.set(now, forKey: "date") 
        } 
       } 
   } 
   

2. 機能（2017年6月16日午前4時57分21秒0000）は

   /* A method for converting Date-with-Time to Date-only String */ 
   func todaysDate(date: Date)-> String { 
       let dateFormatter = DateFormatter() 
       dateFormatter.timeStyle = .none 
       dateFormatter.dateStyle = .long 
       return dateFormatter.string(from: date) 
   } 
   

3. ボタンの動作方法で余分な作業をしてください。ボタンを1回タップすると、残りの日は無効にする必要があるためです。

   @IBAction func spinButtonTapped() { 
       animateSpinButton() 
       // Pick 3 random emojis 
       for i in 0...2 { 
        selectEmojiPickerComponentRow(Int(arc4random_uniform(99)), component: i) 
       } 
       showFeedbackForWinningSpin() 
   
   
       // If the button is Tapped then toggle the button's user interaction property 
       sender.isUserInteractionEnabled = !sender.isUserInteractionEnabled 
       if sender.isUserInteractionEnabled { 
        sender.tintColor = #colorLiteral(red: 0, green: 0.4784313725, blue: 1, alpha: 1) 
       } else { 
        sender.tintColor = #colorLiteral(red: 0.501960814, green: 0.501960814, blue: 0.501960814, alpha: 1) 
       } 
   } 
   

4. 最後にviewWillAppear(_:)方法からconfigureButtonForShowingOnceInADay()を呼び出す：私はタイマーはそのための良いフィットだとは思わない

   override func viewWillAppear(_ animated: Bool) { 
       super.viewWillAppear(animated) 
       configureButtonForShowingOnceInADay() 
   }
