Instance Method

replacementObjectForCoder:

Overridden by subclasses to substitute another object for itself during encoding.

Declaration

- (id)replacementObjectForCoder:(NSCoder *)coder;

Parameters

aCoder

The coder encoding the receiver.

Return Value

The object encode instead of the receiver (if different).

Discussion

An object might encode itself into an archive, but encode a proxy for itself if it’s being encoded for distribution. This method is invoked by NSCoder. NSObject’s implementation returns self.
