Question

私は現在、別の機能のセルから引き続き問題を抱えています。以下は私のコードです。どんな助けでも大歓迎です！

private func datePickerCell(tableView: UITableView, indexPath: IndexPath, property: Property, with value: String, with name: String, changeHandler: @escaping((String) -> Bool)) -> FUISimplePropertyFormCell { 
    let cell = tableView.dequeueReusableCell(withIdentifier: FUISimplePropertyFormCell.reuseIdentifier, for: indexPath) as! FUISimplePropertyFormCell 

    // toolbar 
    let toolbar = UIToolbar() 
    toolbar.sizeToFit() 

    // bar button item 
    let doneButton = UIBarButtonItem(barButtonSystemItem: .done, target: nil, action: #selector(donePressed)) //<-- calls the outside function 
    toolbar.setItems([doneButton], animated: false) 
    cell.valueTextField.inputAccessoryView = toolbar 

    //assigning date picker to text field 
    cell.valueTextField.inputView = datePicker 

    cell.isEditable = true 
    cell.keyName = name 
    cell.value = value 

    return cell 


} 

func donePressed(){ //<-- function that gets called by the done button 
    cell.valueTextField.text = "\(datePicker.date)" // <-- ERROR 
    // i'd like to continue editing the cell here 

}

私のコード自体で説明しましょう。これは私のアプリのために作ったアラーム画面です。この画面では、タイムピッカーを入力フィールドに設定するためのコードの一部があります。あなたの場合、その細胞になること。

これはあなたのやり方です。以下のビューロード機能を確認してください： 以下のコードはフィールド名に変更する必要があり、日付フォーマッタは表示するスタイルを書式設定することです。

私はこれに関する助けが必要かどうかお知らせください。

timeInput.layer.addSublayer(bottomLineTimePicker) 
      dateFormatter.timeZone = TimeZone.current 
      dateFormatter.dateStyle = .none 
      dateFormatter.timeStyle = .short 
      // This is the code you need // 
      timeInput.text = dateFormatter.string(from: timePicker.date) 

これは完全なコードです。

import UIKit 

class Reminder: UIViewController { 

    @IBOutlet weak var timePickerStack: UIStackView! 
    @IBOutlet weak var timeInput: UITextField! 
    @IBOutlet weak var setReminderSwitch: UISwitch! 
    @IBOutlet weak var setReminderButton: UIButton! 

    let timePicker = UIDatePicker() 
    let bottomLineTimePicker = CALayer() 
    let dateFormatter = DateFormatter() 

    @IBAction func setReminder(_ sender: UIButton) { 

     let nextDate = NotificationManager.shared.schedule(time: self.timePicker.date, repeats: true) 

     if nextDate != nil { 

      print("\(nextDate!.timeIntervalSinceNow.formattedTime)") 

     } 
     setReminderStatus(reminderStatus: true,reminderTime:self.timePicker.date) 

    } 

    func createTimePicker(){ 

     timePicker.datePickerMode = .time 

     let toolBar = UIToolbar() 
     toolBar.sizeToFit() 

     let doneButton = UIBarButtonItem(barButtonSystemItem: .done, target: nil, action: #selector(donePressed)) 
     toolBar.setItems([doneButton], animated: true) 

     timeInput.inputAccessoryView = toolBar 
     timeInput.inputView = timePicker 

    } 

    func donePressed(){ 

     dateFormatter.dateStyle = .none 
     dateFormatter.timeStyle = .short 
     timeInput.text = dateFormatter.string(from: timePicker.date) 
     self.view.endEditing(true) 
    } 

    @IBAction func reminderSwitch(_ sender: UISwitch) { 

     if(sender.isOn == true){ 
      timePickerStack.isHidden = false 
     }else{ 
      NotificationManager.shared.cancelAllNotifications() 
      timePickerStack.isHidden = true 
      unsetReminder() 
     } 

    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 


     if(issetReminder()){ 
      setReminderSwitch.setOn(true, animated: true) 
      timePickerStack.isHidden = false 
     }else{ 
      setReminderSwitch.setOn(false, animated: true) 
      timePickerStack.isHidden = true 
     } 

     createTimePicker() 

     bottomLineTimePicker.frame = CGRect(x: 0.0, y: timeInput.frame.height - 1, width: timeInput.frame.width, height: 1.0) 
     bottomLineTimePicker.backgroundColor = UIColor.init(red: 23/255.5, green: 155/255.5, blue: 167/255.5, alpha: 1.0).cgColor 

     timeInput.layer.addSublayer(bottomLineTimePicker) 
     dateFormatter.timeZone = TimeZone.current 
     dateFormatter.dateStyle = .none 
     dateFormatter.timeStyle = .short 
     // This is the code you need // 
     timeInput.text = dateFormatter.string(from: timePicker.date) 

     setReminderButton.layer.cornerRadius = 20.0 
     // Do any additional setup after loading the view. 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 

    @IBAction func backButtonPressed(_ sender: UIButton) { 

     let backButtonPressed = self.storyboard?.instantiateViewController(withIdentifier: "navController") as! IndexNavController 
     self.present(backButtonPressed, animated: true, completion: nil) 

    } 

} 

extension TimeInterval{ 
    var formattedTime:String{ 

     let formatter = DateComponentsFormatter() 
     formatter.unitsStyle = .brief 
     formatter.includesApproximationPhrase = false 
     formatter.includesTimeRemainingPhrase = false 
     formatter.allowedUnits = [.hour, .minute, .second] 
     formatter.calendar = Calendar.current 

     return formatter.string(from: self) ?? "" 

    } 
}
