您好我有一个使用自己的文档格式(.hvgg)的应用程序。 UTI在Info.plist中声明(屏幕截图)。我做错了吗?因为当我使用“共享”菜单时,它显示“复制到HvGG”而不是“导入到HvGG”,它与所有其他应用程序一起显示。
无论如何,我的实际问题是我找不到导入的文件。我试图使用文档目录找到它并添加“收件箱”,但这不起作用。是否有保存文件的新路径?
这是我的代码:
var opened: String?
var path: String?
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
if String(describing: url)[0..<4] == "file" {
opened = "stundenplan"
let filemanager = FileManager.default
let paths: NSArray = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) as NSArray
let documentsDirectory: String = paths.object(at: 0) as! String
path = documentsDirectory.appending("/Inbox")
let dirFiles = try! filemanager.contentsOfDirectory(atPath: path!) <-- throws error
print (dirFiles)
}
return true
}
它返回的错误:
fatal error: 'try!' expression unexpectedly raised an error: Error Domain=NSCocoaErrorDomain Code=260 "The folder “Inbox” doesn’t exist." UserInfo={NSFilePath=/var/mobile/Containers/Data/Application/9C0586AF-C0B8-440A-9151-13C6A061B3FB/Documents/Inbox, NSUserStringVariant=(
