writeAsPlist


Object method


object.writeAsPlist(path);


Write the object to disk as a PropertyList.  It is used commonly in OS X to store data.  


This is an XML format that may be read from easily from Objective-C, Java or any language that uses the CoreFoundation(Cocoa) framework.  


Objective-C:


id rootObject = [NSKeyedUnarchiver  unarchiveObjectWithFile: path ];


The file may be double-clicked to open it in Property List Editor.


 

When opening the PropertyList:


your SC objects are converted to Foundation objects in this fashion:


SimpleNumber -> NSNumber.

SequenceableCollections -> NSArray with each item converted

Strings -> NSString

Symbols -> NSString

Char -> NSString

Nil -> NSNull

Boolean ->NSNumber (numberWithBool:) equivalent to a CFBoolean

Dictionary ->NSDictionary (each item converted)

Other objects  -> NSNull


Most commonly the root object is an NSDictionary or NSArray.
