我有这个映射器:
import Foundation
import ObjectMapper
class Article: Mappable {
var id: Int!
var name: String!
var image: String!
var children: Article!
required init?(_ map: Map) {
mapping(map)
}
func mapping(map: Map) {
id <- map["id"]
name <- map["name"]
image <- map["image"]
children <- map["children"]
}
}
然后我需要循环并通过id找到文章:
func getArticleName(aid) {
for article in articleList {
if aid == article.id {
return article.name
}
for child in article.children {
if aid == child.id {
return child.name
}
}
}
return ""
}
articleList
是Article
可映射类的数组。
现在,当我循环播放儿童时,我收到此错误:
Value of type 'Article' has no member 'Generator'
我如何在子数组中循环?
答案 0 :(得分:1)
我不知道ObjectMapper是什么,但错误信息很简单。你在说:
class Article: Mappable {
var children: Article!
}
因此,文章的children
是一篇文章。那么当你说:
for child in article.children {
......编译器会阻止你;一篇文章,children
就是for ... in
,而不是你可以说GetProject
。
