Question

我正在尝试显示swiftui coredata中仅有的今天或最近24小时输入数据的列表。我不知道语法或逻辑如何获取@FetchRequest谓词上的当日数据。有人可以帮忙，这是显示所有数据的代码

@FetchRequest(
    entity: ExpenseLog.entity(),
    sortDescriptors: [
        NSSortDescriptor(keyPath: \ExpenseLog.date, ascending: true)
    ]
    //,predicate: NSPredicate...
)
private var result: FetchedResults<ExpenseLog>

...

                                ForEach(self.result)
                                {
                                    (log: ExpenseLog) in


                                    ZStack{
                                    HStack(spacing: 16) {
                                                           CategoryImageView(category: log.categoryEnum)
                                                           VStack(alignment: .leading, spacing: 8) {
                                                               Text(log.nameText).font(.headline)
                                                               Text(log.dateText).font(.subheadline)
                                                           }
                                                           Spacer()
                                                           Text(log.amountText).font(.headline)

                                    } .padding(.vertical, 8) .padding(.horizontal,4)
                                      }

                                }

只需使用以下内容过滤列表

Calendar.current.isDateInToday(yourDate)
Calendar.current.isDateInYesterday(yourDate)

仅显示swiftui coredata最近24小时/今天输入的数据
