NSMutableDictionary category

Each method in the NSMutableDictionary category corresponds to a method in the NSMutableDictionary class, but provides a secure version of the functionality. For more information about the functionality and usage, see NSMutableDictionary in developer.apple.com.

Note the following:

•The url parameter in the category methods must be a file URL, and point to a regular file.

•The category methods return an NSError object. The methods set the properties on the object as described in NSError objects that secure Objective-C methods return.

The following table shows each added method and its corresponding method in NSMutableDictionary.
