JSON 对象到字符串 Swift UI

Question



import SwiftUI

extension String{
    func load() ->UIImage {
        
        do{
            //string to URL
            guard let url = URL(string: self) else{
                //empty image if wrong url
                return UIImage()
            }
            //url to data
            let data : Data = try Data(contentsOf: url)
            
            //create uuimage obj from data
            return UIImage(data: data) ?? UIImage()
            
        }catch{
            
            
        }
        return UIImage()
        
    }
}



struct ContentView: View {
    @State private var quoteData : QuoteData?
    
        
    var body: some View {
       
        ZStack{
            VStack{

                
                Text(quoteData?.lat ?? "Latitude")
                Text(quoteData?.long ?? "Longitude")
                

                //------------------------HELP HERE
                Image(uiImage: "https://maps.googleapis.com/maps/api/staticmap?center=LATITUDE,LONGITUDE&zoom=16&size=400x400&key=AIzaSyClGOTMpV2kKF27bxAo6nm3pIq7zmW69Fw".load())

                
struct QuoteData: Decodable{
    
    //var id: Int
    var long: String
    var lat: String
    var apiURL: String

}

我想在 IMAGE(uimage

中使用的 url 字符串中插入 QuoteData 的 long 和 lat 变量

我找不到答案，找了好几个小时都没有运气

这只是代码的一部分，如果有人能帮助我就太好了。

Answer 1

尝试这样的事情，使用 \(lat),\(lon)“...在 url 字符串中插入 QuoteData 的 long 和 lat 变量...”：

struct ContentView: View {

    @State private var quoteData: QuoteData? = QuoteData(long: "139.7514", lat: "35.685", apiURL: "") // for testing, Tokyo
    
    var body: some View {
        VStack{
            Text(quoteData?.lat ?? "Latitude")
            Text(quoteData?.long ?? "Longitude")
            
            if let lat = quoteData?.lat, let lon = quoteData?.long {
                Image(uiImage: "https://maps.googleapis.com/maps/api/staticmap?center=\(lat),\(lon)&zoom=16&size=400x400&key=AIzaSyClGOTMpV2kKF27bxAo6nm3pIq7zmW69Fw".load())
            }
        }
    }
}

PS：这与 JSON object to String

无关
