如何在Struct中调用Struct？

Question

这是一个基本的问题，我是swift的新手，这是一个关于Struct数组的具体问题( Struct is struct)

我正在尝试获得如下输出(TableView结构，标题为部分)：

我可以使用Dictionary来实现，我正在尝试在struct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错误：

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

如何在结构StructSections中调用结构JakartaChannels和MedanChannels？

Answer 1

在此语句中，您传递的是StructChannels数组，但应该只传递StructChannels引用。

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

因此，创建到StructChannels数组的StructSections属性通道。

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
}

}
