Realm-更新對象數組中的所有項目而不是僅添加新項目

Question

我試圖在JournalEntryVC.swift中添加與患者相關的不同日記條目。

我的病人類有軸頸的陣列條目即let journalEntries = List<Journal>()我的期刊類具有表示日記條目即屬性entryType，entryDate和entryCaption性質。

但是，當我在JournalEntryVC.swift中循環JSON時，我的附加日記帳分錄的屬性也被最近的日記帳分錄屬性替換，而不是僅將新日記帳分錄對象追加到日記帳分錄newPatient.journalEntries.append(myJournal)的數組中。

例如，newPatient.journalEntries[0]與entryCaption和entryType具有相同的字符串值，如newPatient.journalEntries[1]等。

主要問題：關於如何添加新日記條目及其屬性但不更改之前附加日記條目的日記條目屬性的任何想法？

謝謝！

你實例化一個實例Journal for循環外的Journal，更改該Journal的值，然後將其附加到患者的JournalEntries。嘗試在for循環中移動let myJournal = Journal()。
