Writes a document placeholder with the provided metadata.
- iOS 8.0–11.0Deprecated
The placeholder URL for the document. You can generate a placeholder URL from a document URL by calling
The metadata for this document.
If an error occurs while writing the placeholder, the error parameter is set to an
NSErrorobject that describes the problem. If you are not interested in the error details, you may pass in
YES, if the placeholder is written successfully; otherwise
Call this method whenever you need to create a placeholder for a document. The metadata that you provide depends largely on the needs of your document picker’s user interface; however, the common options include file size, filename, and thumbnails.
You must not override this method.
