UI构建

继 《自学IOS开发第2天·学习基础SwiftUI》 继续学习。

创建模型 BlogerData.swift

还是用那个项目，创建一个博主的模型，博主的信息有，头像、昵称和个人介绍，根据这些信息，创建一个模型 BlogerData.swift

创建步骤：File > New > File


BlogerData.swift:

import Foundationimport SwiftUIstruct BlogerData :Hashable,Codable{ var id:Int var nickName:String private var face:String var image: Image { Image(face) } } 创建 JSON文件

bolger_data.json：
由于这个文件太长了，放置文章末尾附稿

创建 Model.swift import Foundationvar bolgerData: [BlogerData] = load("bloger_data.json")func load<T: Decodable>(_ filename: String) -> T { let data: Data guard let file = Bundle.main.url(forResource: filename, withExtension: nil) else { fatalError("Couldn't find (filename) in main bundle.") } do { data = try Data(contentsOf: file) } catch { fatalError("Couldn't loaååd (filename) from main bundle:n(error)") } do { let decoder = JSONDecoder() return try decoder.decode(T.self, from: data) } catch { fatalError("Couldn't parse (filename) as (T.self):n(error)") }} 附稿
