By default, UIKit obtains the value from the filename component of
file. You can override the getter accessor method of this property to provide a custom name for presentation to the user, such as in error strings. See “Subclassing Notes” in the class description for overriding advice.
UIKit sets this property before it calls the completion handlers of the
revert(to. If, outside of these methods or their completion handlers, you want to wait for any pending file operations to complete before you access this property, you can call
perform and access the property value in the block parameter.
