我想在我的视图中添加一个按钮来加载更多数据。在我的环境对象中,数据是通过 API 随机生成的。如何重新加载我的 Environment 对象以获取新项目。下面的代码应该清楚。提前致谢
class observer : ObservableObject{
@Published var shows = [stacks]()
@Published var last = -1
var results = [Result1]()
init(){
let number = Int.random(in: 1...35)
print("das ist dier etste radodm nube: \(number)")
let endnumber = number + 8
print("das ist dier etste radodm nube: \(endnumber)")
for n in number...endnumber{
guard let url = URL(string:"https://api.themoviedb.org/3/discover/tv?api_key=3ed2bd15f916d0e3fbb77c193bf33b61&language=de-DE®ion=DE&with_networks=213&page=\(n)" ) else {
print("Invalid URL")
return
}
let request = URLRequest(url: url)
URLSession.shared.dataTask(with: request) { data, response, error in
if let data = data {
if let decodedResponse = try? JSONDecoder().decode(Response.self, from: data) {
DispatchQueue.main.async {
self.results = decodedResponse.results
for i in self.results{
self.shows.append(stacks(id: "\(i.id)", name: i.name, typ: "Serie", status: "",overview: i.overview, vote: "\(i.vote_average)", image: i.poster_path, swipe: 0, degree: 0, commercal: "no"))
}
self.shows.shuffle()
}
return
}
}
print("Fetch failed: \(error?.localizedDescription ?? "Unknown error")")
}.resume()
}
}
}
struct View: View {
@EnvironmentObject var cards : observer
var body: some View {
VStack{
Button(action: {
//reload
}){
Text("reload")
}
}
