ios - Realm -更新对象数组中的所有项目，而不是仅添加新项目

我试图在JournalEntryVC.swift中添加与患者相关的不同日记条目。
我的病人类有一个日记条目数组，即let journalEntries = List<Journal>()我的日记类有表示日记条目属性的属性，即entryType、entryDate和entryCaption。
但是，在JournalEntryVC.swift中循环json时，不仅向日记条目数组附加新的日记条目对象，而且以前附加的日记条目属性也被最新的日记条目属性替换。
例如，newPatient.journalEntries.append(myJournal)的newPatient.journalEntries[0]和entryCaption的字符串值与entryType相同，以此类推。
主要问题：对于如何添加新的日记账分录及其属性，但不更改以前附加日记账分录的日记账分录属性，有何想法？
谢谢您！

最佳答案

在for循环外实例化Journal的单个实例，更改该Journal的值，然后将其附加到患者的journalEntries。尝试在for循环中移动let myJournal = Journal()。
