打印按钮集合中的整数数组，Swift
打印按钮集合中的整数数组，Swift
提问于 2016-09-26 04:14:47
我正在用Xcode创建一个问答游戏，在问答完成后，我有一个屏幕，其中显示了所问的5个问题(来自70+数组)，以及相应的正确答案(答案)和用户选择的答案(UserAnswer)。
我目前有一个正确答案(CorrectAnswer)的标签集合和一个单独的user answers YourAnswer标签集合。我希望连续打印为5个标签(QuestionName、YourAnswer、CorrectAnswer)集合中的每个数组存储的所有5个值。
我是编程新手，所以任何在循环中使用数组的帮助都将不胜感激。
First View Controller：
struct Question {
var Question : String
var Answers : [String]!
var Answer : Int!
var UserAnswer : Int!
}
var Questions = [Question]()第二个视图控制器：
class ScoreViewController: UIViewController {
var Questions = [Question]()
var CorrectAnswerTotal = Int()
var QuestionNumberTotal = Int()
let TOTAL_QUESTIONS = 0
var AnswerNumber = Int()
@IBOutlet var QuestionName: [UILabel]!
@IBOutlet var YourAnswer: [UILabel]!
@IBOutlet var CorrectAnswer: [UILabel]!
for i in 0..<Questions.count {
var q = Questions[i].Question
var ai = Questions[i].Answer
var a = Questions[i].Answers[ai]
var uai = Questions[i].UserAnswer
var ua = Questions[i].Answers[uai]
//This is where the error is
if QuestionNumberTotal < TOTAL_QUESTIONS {
if (ai != uai){
QuestionName.text = Questions[i].Question
YourAnswer.text = Questions[i].UserAnswer
CorrectAnswer.text = Questions[i].Answer
}回答 1
