ios - 如何在结构内部调用结构？

Question

这是一个基本问题，我是 swift 的新手，这是一个关于结构数组的特定问题(Struct inside struct)

我正在尝试像这样输出(以标题作为部分的 TableView 结构):

我可以用字典来做，我正在尝试在结构中创建数组

结构:

struct StructSections {
    var sectionName: String!
    var channels: StructChannels
    var collapsed: Bool!

    init(sectionName: String, channels: StructChannels, collapsed: Bool = false) {
        self.sectionName = sectionName
        self.channels = channels
        self.collapsed = collapsed
    }
}

struct StructChannels{
    var channelName: String!
    var streamURL: String!
    var imageURL: String!
}

然后我创建函数来加载数据

func CreateRadioData() {
    var JakartaChannels: [StructChannels] = []
    JakartaChannels = [
        StructChannels(channelName: "Prambors 102.2 FM Jakarta", streamURL: "http://masima.rastream.com/masima-pramborsjakarta", imageURL: "PramborsJakarta"),
        StructChannels(channelName: "I-Radio 89.6 FM Jakarta", streamURL: "http://mra.rastream.com/mra_iradio", imageURL: "IRadioJakarta")
    ]

    var MedanChannels: [StructChannels] = []
    MedanChannels = [
        StructChannels(channelName: "KISS 105 FM Medan", streamURL: "http://live.kissfm-medan.com:8080/kissfm.mp3", imageURL: "KissFMMedan")
    ]



    var Sections:[StructSections] = []
    Sections = [
        StructSections(sectionName: "Jakarta", channels: JakartaChannels),
        StructSections(sectionName: "Medan", channels: MedanChannels)
    ]
}

我在这些代码中遇到了错误:

 StructSections(sectionName: "Jakarta", channels: JakartaChannels),
 StructSections(sectionName: "Medan", channels: MedanChannels)

如何调用 StructSections 结构体中的 JakartaChannels 和 MedanChannels 结构体？

Answer 1

在此声明中，您传递的是 StructChannels 数组，但预计只有 StructChannels ref。

StructSections(sectionName: "Jakarta", channels: JakartaChannels)

因此，创建 StructSections 属性 channel 到 StructChannels 数组。

struct StructSections {
var sectionName: String!
var channels: [StructChannels]
var collapsed: Bool!

init(sectionName: String, channels: [StructChannels], collapsed: Bool = false) {
  self.sectionName = sectionName
  self.channels = channels
  self.collapsed = collapsed
}
