可能通过可可协定获得核心数据关系最后要素的适当途径
原标题:Proper way to get possibly through Cocoa Bindings the last element of a relationship in Core Data

我有一个管理目标X,与[1:N]Y物体清单的关系(X和Y物体使用核心数据储存)

我想找到适当的(更方便)途径,以获得最新插入的Y物体。 这一Y物体的“名称”属性应在可能时通过Cocoa Biles显示。

我知道,所有的Ys都插入了国家安全局,因此没有定局。 然而,每名Y人都有“时间”的属性,因此,当我说“最新插入的Y物体”时,我实际上指的是“最晚的Y”。

任何帮助都将得到赞赏: 我搜查了所有文件,但没有发现任何东西可以帮助我。
