Moves the document’s file to the given URL.
- macOS 10.8+
The location where the file will ultimately end up, if the move is successful.
The completion handler block object passed in to be invoked at some point in the future, perhaps after the method invocation has returned. The completion handler must be invoked on the main thread. On output, a
nilerror is passed if the move is successful; otherwise an
NSErrorobject is passed that encapsulates the reason for failure.
The default implementation of this method replaces any file that may currently exist at the given URL with the one being moved, as necessary.
