ICloud Container(IOS)

Before​

You maybe be frustrated if used wrong path format: passing file schema or not, relative or absolute path:

  • localPath: means you should pass a full file path with or without schema, for example:
    • file:///path/to/app/documents/my/file.txt ok
    • /path/to/app/documents/my/file.txt ok
    • /my/file.txt not ok
  • icloudPath: means you can pass a full icloud path or relative icloud file path(ends or starts with '/' not matter), for example:
    • /path/to/icloud-container/my/file.txt ok
    • my/file.txt ok
    • /my/file.txt ok
