我有一系列的友情ID&组ID。从这里我必须过滤匹配的朋友和具有来自我的其他数组的ID的组,其中包含朋友,组。
let friendIDS = ["DW548ADS456", "DSAD86465"]
let groupIDS = ["RQ13131"]
现在如何过滤我的项目,以便我将拥有Group&拥有以上匹配ID的朋友
我是通过这种方式尝试的,但不知道如何在该过滤器中搜索匹配的ID
var items = [Conversation]()
let friendIDS = ["DW548ADS456", "DSAD86465"]
let groupIDS = ["RQ13131"]
self.filtereditems = self.items.filter {
$0.groupDetails?.groupID == ""
$0.user?.userId == ""
}
会话课
class Conversation {
//MARK: Properties
let user: User?
let groupDetails: GroupDetails?
}
struct User: JSONDeserializable {
var userId: String = ""
init(userId: String)
self.userId = userId
}
class GroupDetails: NSObject {
//MARK: Properties
let groupID: String
init(groupID: String){
self.groupID = groupID
}
答案 0 :(得分:1)
如果我做对了,
struct user {
var groupID: String
var userID: String
}
let items = [
user.init(groupID: "RQ13131", userID: "DSAD86465"),
user.init(groupID: "1", userID: "DW548ADS456"),
user.init(groupID: "2", userID: "DW548ADS456")
]
let friendIDS = ["DW548ADS456", "DSAD86465"]
let groupIDS = ["RQ13131"]
let filtereditems = items.filter {
groupIDS.contains($0.groupID) ||
friendIDS.contains($0.userID)
}
print(filtereditems)
打印
[user(groupID:“RQ13131”,userID:“DSAD86465”)]
