在滾動檢視上新增子檢視（UIScrollView）
阿新 • • 發佈：2019-01-04
在我做一個學習APP的時候，遇到讓我很頭疼的問題，頭疼的原因是因為我自己太菜了吧！
APP的大部分功能都是在一個滾動檢視上完成的，幾乎所有頁面都加在滾動檢視上的，因為每一頁都是一道題目，而且題目非常多，每個年級每一單元這樣來分類的。
題目型別也比較多，我不可能一道題都設計一個頁面吧，這樣肯定是不可能的，所以我就每個型別的題目設計了一個介面。
後來問題來了，我該怎麼從json檔案中取出每道題然後一道一道，一中型別一種型別地載入頁面呢？
因為每種型別的題目有多項，而且是一種型別完了之後才會有另一型別的題目。
後來糾結鬱悶思考之後解決了，部分程式碼如下((⊙o⊙)…，還是貼一個類算了吧，嘟嘟嘟嘟嘟...)：
