Creates and returns an instance of a scriptable class, setting its contents and properties, for insertion into the relationship identified by the key.
- macOS 10.5+
The class of the scriptable object to be created.
A key that identifies the relationship into which the new class object will be inserted.
Specifies the contents of the object to be created. This may be
nil. (See also the Discussion section.)
The properties to be set in the new object. (See also the Discussion section.)
The new object. Returns
nil if an error occurs.
You can override the
new method to take more control when your application is sent a
make command. This method is invoked on the prospective container of the new object. The
properties are derived from the
with contents and
with properties parameters of the
make command. The returned objects or objects are then inserted into the container using key-value coding.
When this method is invoked by Cocoa, neither the contents value nor the properties will have yet been coerced using the
coerce. For sdef-declared scriptability, however, the types of the passed-in objects reliably match the relevant sdef declarations.
The default implementation of this method creates new scripting objects by sending
alloc to a class and
init to the resulting object. You override this method for situations where this is not sufficient, such as in Core Data applications, in which new objects must be initialized with
