«„ViewController.Type“не имеет член с именем...»

Question

я создал две переменные, поплавки:

var yourWeight = (yourWeightTextField.text as NSString).floatValue 
var calorieNumber = (calorieNumberTextField.text as NSString).floatValue 

я получил следующие ошибки:

// 'ViewController' does not have a member named 'yourWeightTextField' 
// 'ViewController' does not have a member named 'yourWeightTextField' 

У меня есть установить мои IBOutlets:

class ViewController: UIViewController, UITextFieldDelegate, UIPickerViewDelegate, UIPickerViewDataSource { 

@IBOutlet weak var calculatorButton: UIButton! 
@IBOutlet weak var inspirationLabel: UILabel! 
@IBOutlet weak var beginningLabel: UILabel! 
@IBOutlet weak var calculatorContainer: UIView! 
@IBOutlet weak var answer1Label: UILabel! 
@IBOutlet weak var doneButton: UIButton! 
@IBOutlet weak var yourWeightTextField: UITextField! 
@IBOutlet weak var exerciseListPickerView: UIPickerView! 
@IBOutlet weak var calorieNumberTextField: UITextField! 
@IBOutlet weak var menuExampleButton: UIButton! 
@IBOutlet weak var aboutButton: UIButton! 
@IBOutlet weak var calculateButton: UIButton! 

Вот мой ViewDidLoad Метод:

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib 
    yourWeightTextField.delegate = self 
    calorieNumberTextField.delegate = self 
    exerciseListPickerView.delegate = self 
    exerciseListPickerView.dataSource = self 
    calculateButton.enabled = false 
    // Calling the textfield valueChanged Methods 
    yourWeightTextField.addTarget(self, action:"yourWeightEditingChanged:", forControlEvents:.EditingChanged); 
    calorieNumberTextField.addTarget(self, action:"calorieNumberEditingChanged:", forControlEvents:.EditingChanged); 
} 

Вот остальная часть кода:

var yourWeight = (yourWeightTextField.text as NSString).floatValue 
var calorieNumber = (calorieNumberTextField.text as NSString).floatValue 
var exerciseCurrentValue:Float = 0.009 
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) { 
    switch (row) { 
    case (0): 
     exerciseCurrentValue = 0.009 
    case (1): 
     exerciseCurrentValue = 0.019 
    case (2): 
     exerciseCurrentValue = 0.023 
    case (3): 
     exerciseCurrentValue = 0.029 
    case (4): 
     exerciseCurrentValue = 0.045 
    case (5): 
     exerciseCurrentValue = 0.033 
    case (6): 
     exerciseCurrentValue = 0.038 
    case (7): 
     exerciseCurrentValue = 0.038 
    case (8): 
     exerciseCurrentValue = 0.039 
    case (9): 
     exerciseCurrentValue = 0.053 
    case (10): 
     exerciseCurrentValue = 0.061 
    case (11): 
     exerciseCurrentValue = 0.063 
    case (12): 
     exerciseCurrentValue = 0.063 
    case (13): 
     exerciseCurrentValue = 0.064 
    case (14): 
     exerciseCurrentValue = 0.076 
    case (15): 
     exerciseCurrentValue = 0.083 
    default: 
     exerciseCurrentValue = 0.009 
    } 
} 

@IBAction func calculateButtonTapped(sender: AnyObject) { 
    answer1Label.text = "It will take you \((exerciseCurrentValue)/((yourWeight) * (calorieNumber))) minutes to burn off those calories by performing that exercise." 
} 

Я также получил другую ошибку на

, но я предполагаю, что это будет исправлено:

// 'ViewController' does not have a member named 'yourWeight' 

Просьба так много кода возможно, потому что я новичок в программировании. Спасибо!

Answer 1

Вы не можете назначать свойства с значениями экземпляра.

Необходимо определить ваши свойства следующим образом.

var yourWeight:Float = 0 // Or whatever default value you want 
var calorieNumber:Float = 0 // Or whatever default value you want 

Тогда в viewDidLoad и везде, где вам нужно, чтобы получить значения, сделайте следующее:

self.yourWeight = (self.yourWeightTextField.text as NSString).floatValue 
self.calorieNumber = (self.calorieNumberTextField.text as NSString).floatValue
