Question

我正在尝试实现查看屏幕截图。运行代码时，出现一些错误，捕获失败。

这是我的代码：

func saveSelfAsImage() {
    self.lockFocus()
    let image = NSImage(data: self.dataWithPDF(inside: self.bounds))
    self.unlockFocus()
    let imageData = image!.tiffRepresentation

    let fileManager = FileManager.default
    let path = "/Users/wudi/Documents/image.png"
    fileManager.createFile(atPath: path, contents: imageData, attributes: nil)

    let fileURL = URL(fileURLWithPath: path)
    NSWorkspace.shared.activateFileViewerSelecting([fileURL])
}

这是错误日志：

日志显示客户缺少权利。但是如何获得权利？我用关键字在日志中搜索了错误，但没有发现有用的东西。有人遇到过类似的问题吗？

问题已解决。感谢EI Tomato和Willeke的帮助。

关闭应用程序沙箱或增加文件访问权限可以解决此问题。
