恐龍問題app：實作segue傳遞資料

原本的app只能在同一頁上顯示，現在透過segue讓app可以在不同分頁中傳遞資料。

連線示意圖

跑完十題後不靠按鈕直接跳到下一頁的方法：從初始頁的上面最左邊那顆按鈕連線到要呈現的畫面！

參考同學詳細的說明！

台羅小測驗app：實作segue傳送資料、Auto Layout等功能

restart按鍵拉回第一頁就可以重新開始了！

程式碼

總共分成四頁

一頁存放Qnas，另外三頁就是起始頁、問題頁、結尾頁

//設定一個Swift File取名File.swift
import Foundation
struct Qnas {
var question: String
var option: [String]
var answer: String
}

起始頁的部分只有連結button到下一頁

問題頁
