我想知道是否有人可以帮我回答以下问题。此代码的情况一将询问名称，您可以单击四个选项之一来选择正确的答案。我想知道如何才能输入问题的答案，例如:
What is my name?
My name is "Type answer here"
"Cesar"
"Karlos"
"William"
"Chiqui"
这是我现有的代码:
import UIKit
class ViewController: UIViewController {
@IBOutlet weak var QuestionLabel: UILabel!
@IBOutlet weak var Button1: UIButton!
@IBOutlet weak var Button2: UIButton!
@IBOutlet weak var Button3: UIButton!
@IBOutlet weak var Button4: UIButton!
@IBOutlet weak var Next: UIButton!
@IBOutlet weak var LabelEnd: UILabel!
var CorrectAnswer = String()
var randomQuestionArray: [Int] = [1, 2, 3, 4]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
RamdomQuestions()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func RamdomQuestions () {
let randomIndex = Int(arc4random_uniform(UInt32(randomQuestionArray.count)))
switch (randomQuestionArray[randomIndex]) {
case 1:
QuestionLabel.text = "What is my name? "
Button1.setTitle ("Cesar", forState: UIControlState.Normal)
Button2.setTitle ("Karlos", forState: UIControlState.Normal)
Button3.setTitle ("William", forState: UIControlState.Normal)
Button4.setTitle ("Chiqui", forState: UIControlState.Normal)
CorrectAnswer = "2"
break
case 2:
QuestionLabel.text = "What is my last name? "
Button1.setTitle ("Perez", forState: UIControlState.Normal)
Button2.setTitle ("Carvajal", forState: UIControlState.Normal)
Button3.setTitle ("Garcia", forState: UIControlState.Normal)
Button4.setTitle ("Sanchez", forState: UIControlState.Normal)
CorrectAnswer = "1"
break
case 3:
QuestionLabel.text = "What is my favorite dish? "
Button1.setTitle ("Pasta", forState: UIControlState.Normal)
Button2.setTitle ("Fish", forState: UIControlState.Normal)
Button3.setTitle ("Vegetables", forState: UIControlState.Normal)
Button4.setTitle ("McMc", forState: UIControlState.Normal)
CorrectAnswer = "1"
break
case 4:
QuestionLabel.text = "What is my favorite color"
Button1.setTitle ("Red", forState: UIControlState.Normal)
Button2.setTitle ("Blue", forState: UIControlState.Normal)
Button3.setTitle ("Orange", forState: UIControlState.Normal)
Button4.setTitle ("Black", forState: UIControlState.Normal)
CorrectAnswer = "4"
break
default:
break
}
randomQuestionArray.removeAtIndex(randomIndex)
}
func Hide (){
LabelEnd.hidden = true
Next.hidden = true
}
func UnHide () {
LabelEnd.hidden = false
Next.hidden = false
}
@IBAction func Button1Action(sender: AnyObject) {
UnHide()
if (CorrectAnswer == "1") {
LabelEnd.text = "Correcto"
}
else{
LabelEnd.text = "Falso"
}
}
func Button2Action(sender: AnyObject) {
UnHide()
if (CorrectAnswer == "2") {
LabelEnd.text = "Correcto"
}
else{
LabelEnd.text = "Falso"
}
}
func Button3Action(sender: AnyObject) {
UnHide()
if (CorrectAnswer == "3") {
LabelEnd.text = "Correcto"
}
else{
LabelEnd.text = "Falso"
}
}
func Button4Action(sender: AnyObject) {
UnHide()
if (CorrectAnswer == "4") {
LabelEnd.text = "Correcto"
}
else{
LabelEnd.text = "Falso"
}
}
@IBAction func Next(sender: AnyObject) {
RamdomQuestions()
}
}
最佳答案
您可以使用 UITextField 输入问题的答案。但是，这不是一个好方法，因为您必须处理所有大写/小写字母场景。
例如-用户可以通过以下方式输入名称:
"Cesar", "cesar", "CESAR"
为了避免所有这些处理，最好使用 UIButton。
