ios - 核心数据: Select entities matching certain criteria

Question

有人可以给出一段 Swift 代码如何实现以下场景:

有一个核心日期员工有两个属性名字和姓氏，你将如何排序所有姓氏以字母“K”结尾的员工

Answer 1

基本上，您希望将 NSPredicate 与 ENDSWITH 比较一起使用

let term = "K"
let request = NSFetchRequest(entityName: "Employee")
let namePred = NSPredicate(format: "last_name ENDSWITH[cd] %@", term)

let people = (try context.executeFetchRequest(request) as? [Employee]) ?? []
