更改texttextcolor为UITextField

我想改变textColor.Though我正确地输入到文本字段中的数字，它只适用于“其他”条件，但不适用于'如果'。这是我的代码。更改texttextcolor为UITextField

任何人都可以解决此问题。由于

class ViewController: UIViewController, UITextFieldDelegate { 

@IBOutlet weak var questionOne: UILabel! 
@IBOutlet weak var fieldOne: UITextField! // textFields should be set as labels 

@IBOutlet weak var questionTwo: UILabel! 
@IBOutlet weak var fieldTwo: UITextField! 

@IBOutlet weak var questionThree: UILabel! 
@IBOutlet weak var fieldThree: UITextField! 


@IBOutlet weak var questionFour: UILabel! 
@IBOutlet weak var fieldFour: UITextField! 


@IBAction func submitButton(sender: UIButton) { 
    fieldOneColorChange() 
    fieldTwoColorChange() 
    fieldThreeColorChange() 
    fieldFourColorChange() 
} 

@IBAction func resetButton(sender: UIButton) { 
} 

// Text color changes 

func fieldOneColorChange() { 
    if fieldOne == 1 { 
     questionOne.textColor = UIColor.redColor() 
    } else { 
     questionOne.textColor = UIColor.blueColor() 

    } 
} 

func fieldTwoColorChange() { 
    if fieldTwo == 2 { 
     questionTwo.textColor = UIColor.brownColor() 
    } else { 
     questionTwo.textColor = UIColor.redColor() 

    } 
} 

func fieldThreeColorChange(){ 
    if fieldThree == 3 { 
     questionThree.textColor = UIColor.blueColor() 
    } else { 
     questionThree.textColor = UIColor.purpleColor() 
    } 
} 

func fieldFourColorChange(){ 
    if fieldFour == 4 { 
     questionFour.textColor = UIColor.blueColor() 
    } else { 
     questionFour.textColor = UIColor.redColor() 

    } 
}

'如果fieldOne.text == “1”' –

@Pyro他有一个出口每个领域为什么他需要标记他们？正如OP所述“当我在文本框中正确输入数字时” –

@LeoDabus非常感谢。有效。 – Terril320

等方式更改if语句，这样

if fieldOne.text=="1"

分别为每if语句
