我希望有人可以幫助,我在我的智慧結束試圖弄清楚這一點!需要重新加載/重新計算NSArray
基本上我有一個JSON feed將數據拖入一個NSDictionary
,並帶有一個額外的文件(.h和.m)添加一些與當前時間相關的條件字段。我需要每隔x分鐘更新/刷新條件字段,而無需從JSON訂閱源重新加載/提取數據。相反,我想重新運行條件測試並用最初創建的數據庫更新數據庫。
有沒有人有任何線索如何做到這一點,我到處研究,找不到答案!
僅供參考這裏是有條件的參數設置額外的字段/實體數據庫:

「代碼格式化」用於代碼,而不是強調。此外,您的問題是您希望其他人爲您修改的代碼轉儲,這使得它的質量很低。此外,僅僅說明你研究了你的問題並不符合研究的要求。 – dandan78
嗨丹,感謝您的意見,但我擔心你完全錯了,我正試圖在這裏學習。再一次感謝你們低質量的批評,並且自負地假設/傲慢的輸入(!) – user1419810
