macOS 计算机中的 SwiftUI Catalyst App - 我应该使用哪个路径将图像保存在我的 Mac 本地磁盘中? [英] SwiftUI Catalyst App in macOS computer - Which path should I use to save an image in my Mac local disk?

问题描述

我有这个简单的代码，我在 macOS 中使用 Catalyst 运行:

I have this simply code, that I run with Catalyst in macOS:

struct ContentView: View {

    @State private var pathURL = "/Users/cesare/Desktop/Test"

    var body: some View {
        VStack {
            TextField("/Users/cesare/Desktop/Test", text: $pathURL)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()
            Button(action: {
                let fileUrl = URL(fileURLWithPath: self.pathURL, isDirectory: true)

                let nameImage = "ImageTest" + ".jpg"
                let fileUrlWithName = fileUrl.appendingPathComponent(nameImage)

                let imageData = UIImage(named: "2020-03-05_11-19-22_5")?.jpegData(compressionQuality: 1)
                do {
                    try imageData!.write(to: fileUrlWithName)
                } catch {
                    print("** saveImageData error: \(error.localizedDescription)")
                }
            }) {
                Text("Save Image")
            }
        }
    }
}

在 Assets.xcassets 中，我放了 2020-03-05_11-19-22_5 图像.当我按下 Save Image 按钮时，出现此错误:您无权将文件ImageTest.jpg"保存在文件夹Test"中.为什么我没有在桌面上保存图像的权限?我试图导出产品中包含的应用程序，但没有得到任何结果.我应该使用哪个路径在 Mac 本地磁盘中保存图像?

In Assets.xcassets I put 2020-03-05_11-19-22_5 image. When I press Save Image button, I have this error: You don’t have permission to save the file "ImageTest.jpg" in the folder "Test". Why I don't have permission for save image in my Desktop? I tried to export the app contained in Products, without getting any results. Which path should I use to save an image in my Mac local disk?

推荐答案

要将文档保存在任意文件夹中，需要将 App Sandbox 设置为 NO.

To save the document in any folder, you need to set the App Sandbox to NO.
