如何从 macOS Swift 上的文档目录加载图像?

问题描述

我正在努力将图像加载到 Image.我正在制作一个与 iOS 略有不同的 MacOS 应用.

I am struggling with loading an image to Image. I am making an MacOS app which is slightly different than for iOS.

我搜索了互联网，但我只找到了几个如何在 iOS 中制作它的答案.

I searched Internet however I found only several responses how to make it in iOS.

请检查代码:

import SwiftUI
struct ContentView: View {
    let myUrl = URL(fileURLWithPath: "/Users/codegrinder/Documents/turtlerock.jpg")
    init() {
        //TODO Do something with the myUrl which is valid (not nil)
    }
    var body: some View {
        Image("turtlerock")
            .frame(maxWidth: .infinity, maxHeight: .infinity, alignment:.center)
       //I need to put the param to Image what I want to load an image from myUrl

    }
}

---

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

推荐答案

首先点击你的应用目标 >签署&并删除应用沙盒，如下图所示:

First click on your app target > signing & capabilities and remove the App Sandbox as shown in the following picture:

现在您可以访问不在您的应用程序包中的文件.

Now you can access files that are not located inside your app bundle.

struct ContentView: View {
    let image = NSImage(contentsOf: URL(fileURLWithPath: "/Users/codegrinder/Documents/turtlerock.jpg"))!
    var body: some View {
        Image(nsImage: image)
            .frame(maxWidth: .infinity, maxHeight: .infinity, alignment:.center)
    }
}
