swiftui Swift 问题 顺便求推荐 ios 开发的讨论群

emmm

由于没啥人解答 我动了动脑子 试出了这个办法

刚学 swift 和 swiftui 3 天 代码水平一言难尽 希望大家多提意见

pwnedInfo:
{
data = "Passwords, Email addresses";
date = "2017-04-15";
title = Youku;
url = "https://monitor.firefox.com/breach-details/Youku";
},
{
data = "Email addresses";
date = "2016-06-30";
title = Tianya;
url = "https://monitor.firefox.com/breach-details/Tianya";
},
{
data = "Passwords, IP addresses";
date = "2015-10-26";
title = 000webhost;
url = "https://monitor.firefox.com/breach-details/000webhost";
}

var pwnedInfo: NSMutableArray = []
var pwnedInfoDict: [String: [String: String]] = [:]

var id: Int = 0
for i in pwnedInfo {
pwnedInfoDict[String(id)] = (i as? [String: String])
id = id + 1
}

swiftUI 相关代码：

struct showInfo: View {
@Binding var popoverIsShown: Bool
var body: some View {
let keys = pwnedInfoDict.map { $0.key }
let values = pwnedInfoDict.map { $0.value }

List {
ForEach(keys.indices) { index in
// var x = print((values[index]))
let title = (values[index]["title"]!)

if values[index]["date"] != nil {
let date = (values[index]["date"]!)
}
if values[index]["data"] != nil {
let data = (values[index]["data"]!)
}
let url = (values[index]["url"]!)
}
}
}
}

···· json 转模型呀···· swift 原生的或者三方的，很多成熟的框架

@xtinput 刚开始学 模型都没接触呢。。。

```json
{
"userData": "xxx@xxx.com",
"pwnedCount": "3",
"pwnedInfo": [
{"title": "Youku",
"url": "https://monitor.firefox.com/breach-details/Youku",
"date": "2017-04-15",
"data": "Passwords, Email addresses"
},
{"title": "Tianya",
"url": "https://monitor.firefox.com/breach-details/Tianya",
"date": "2016-06-30",
"data": "Email addresses"
},
{"title": "000webhost",
"url": "https://monitor.firefox.com/breach-details/000webhost",
"date": "2015-10-26",
"data": "Passwords, IP addresses"}
],
"returnCode": 200
}
```



```swift
//Model 解析 JSON 数据
struct Ccdjh: Codable,Hashable {
var userData : String?
var pwnedCount : String?
var returnCode:String?
var pwnedInfo:[CcdjhPwnedInfo]?
}

struct CcdjhPwnedInfo: Codable,Hashable {
var title : String?
var url : String?
var date:String?
var data:String?
}

//Test 数据

let p1 = CcdjhPwnedInfo(
title: "Youku",
url: "https://monitor.firefox.com/breach-details/Youku",
date: "2017-04-15",
data: "Passwords, Email addresses"
)

let p2 = CcdjhPwnedInfo(
title: "Tianya",
url: "https://monitor.firefox.com/breach-details/Tianya",
date: "2016-06-30",
data: "Email addresses"
)

let p3 = CcdjhPwnedInfo(
title: "000webhost",
url: "https://monitor.firefox.com/breach-details/000webhost",
date: "2015-10-26",
data: "Passwords, IP addresses"
)

let Cc = Ccdjh(
userData: "xxx@xxx.com",
pwnedCount: "3",
returnCode: 200,
pwnedInfo: [p1,p2,p3]
)

//使用数据
Text("\(Cc.userData!)")

```
